At the churchyard of Eccleston, a few minutes’ walk from the gates of Eaton Hall, a small stone memorial marks the grave of a boy who died at four years old. His name was Edward, and he was the only son the richest man in Britain would ever father, though his father did not know that yet when the stone was cut. He would spend the next four decades and four marriages trying to prove it wrong, and every attempt would fail. The boy lay under the stone, and the fortune that owned half of Mayfair and a house of fifty-four bedrooms and more acres than a man could walk across in a week rolled on through the century without him.

When his father died at last, the dukedom he had spent his whole life trying to keep in his own blood passed sideways to a cousin, as though the four weddings had never happened. The fortune found its heir. It simply refused to come from him. He was named after a racehorse, and he came into an empire of rent before he was old enough to understand what it meant.

His name was Hugh Richard Arthur Grosvenor, though almost no one ever used it. From boyhood he was called Bendor, after Bend Or, the chestnut colt his grandfather owned that won the Derby at Epsom in 1880, the year after the boy was born. The horse had its single golden afternoon; the name fixed itself to the child. For the rest of his long life, kings and prime ministers and every woman he married would call him by the name of an animal that ran fast once.

He was born on the nineteenth of March, 1879, into the very highest reach of the English aristocracy, and yet the great inheritance reached him by a crooked path. His father, Lord Henry Grosvenor, died before the dukedom could ever come to him, so the title skipped a generation. When the first Duke of Westminster died in December of 1899, the whole vast estate leapt clean over the dead father and landed on the twenty-year-old grandson. Overnight, without effort or achievement, Bendor became the second Duke of Westminster and one of the richest human beings then alive.

He inherited the entailed Grosvenor estates, more than a hundred and thirty thousand acres spread across Britain. He inherited the freehold of much of Mayfair and Belgravia, the most valuable ground in the country, streets where every house and shop and embassy paid the family for the privilege of standing there. He inherited Eaton Hall in Cheshire, a country palace counted in dozens of bedrooms and set in thousands of acres of its own park. He was a young man handed the keys to a kingdom of brick and rent, and he had done nothing to earn a single stone of it beyond being born to the right grandfather at the right hour.

The Grosvenors had held that ground for centuries. The family fortune had grown not by daring or invention, but by the slow accident of London swelling outward across land they happened to own, where their ancestors had held fields and marsh on the western edge of the old city. The capital spread and built and multiplied until the family found itself holding the freehold of the grandest addresses in the kingdom and drawing rent from them without lifting a hand. It was wealth of the oldest and safest kind, wealth that did not have to be won each morning, and by the time it descended to Bendor it had compounded into a fortune with almost no equal in the country.

From the age of twenty he was a landlord to embassies and dukes and millionaires, the man who owned the floor beneath the feet of fashionable London. There is one word that has to be understood before any of the rest of the story makes sense, and that word is entail. The Grosvenor estate was entailed, which is to say it was bound by law to descend down a single male line, from father to son to grandson, and it could not be freely given away or left as a man chose. A daughter could not inherit the dukedom.

A daughter could not hold the great estate. Without a son of his own body, everything Bendor now owned—the rent, the acres, the houses, the paintings on their walls—would one day slide off his line entirely and pass to whatever male cousin stood next in the succession. The fortune, in other words, did not truly belong to him. He was a caretaker of it, and the rent of the estate was, in the cold language of the law, a debt owed to a son he had not yet made.

The entail did not care whether a man loved his wife or hated her, whether he was happy or wretched, whether his daughters were clever and devoted or his cousins were strangers he had never met. It cared about one thing only: a male heir of the body. A man could own more of the country than almost anyone alive and still, if he failed to produce a son, watch the whole inheritance prepare to step around him. For a young duke of twenty, freshly rich and endlessly indulged, this was an abstract clause in a dusty settlement, easy to leave to the future.

It would not stay abstract. In time it would become the single fact that governed the rest of his life. The great English estates did not pass to the ablest child, or the kindest, or the one who loved the land the most. They passed under the old rule of primogeniture, to the eldest surviving son and to no one else.

And if there was no son at all, the whole edifice went to the nearest male relative in the line, however distant. A duke was in a sense married to that rule long before he was ever married to a woman. His first duty, ahead of happiness, ahead of love, ahead of everything, was to make the boy who would keep the name and the ground together for one more generation. Bendor had been born into that duty.

And for a long while he treated it as lightly as he treated everything else, because for a long while, like everything else, it seemed to be taking care of itself. The Grosvenors were not a family whose fortune could be carried off in a strong box. It was land, fixed and enormous and scattered across Britain, and it came with an entire world attached to it: the tenants and the farms, the gardeners and grooms and gamekeepers, the small standing army of servants it took to keep a house of fifty-four bedrooms alive, the agents who gathered the London rents street by street. To be the Duke of Westminster was to sit at the head of something closer to a small principality than a private fortune.

The entail existed precisely to make certain that principality was never broken up, but passed down whole from one male heir to the next. It was a magnificent machine for preserving wealth, and it had exactly one weakness. It could not manufacture the heir it required. It could only wait for him.

And when he did not come, it did not bend or adapt or make an exception for grief or wealth or good intentions. It simply reached past the man who had failed to produce him and found somebody else. For now, Bendor had every reason to believe the future would arrange itself as smoothly as everything else in his life had. He was tall and fair and physically fearless, charming in the careless way of men who have never once been told no.

He went to war in South Africa against the Boers and won a decoration for it, and there on the veldt he first fell into the company of a young officer and correspondent named Winston Churchill, beginning a friendship that would run through everything that followed and last until Bendor’s death. He would soldier again and harder in the Great War and collect his honors and his titles. In between, he hunted and raced and drove fast motorcars when a motorcar was still a rich man’s toy, and he moved through the world with the easy certainty of a man for whom the world had always made room. What he did not yet know was that the one thing his fortune most needed from him was the one thing his fortune could not command.

It could buy him a house on any street he fancied. It could buy him horses and yachts and the good opinion of half of London. It could not buy him a living son. And the estate, patient and indifferent, would go on waiting for that son through four marriages and more than forty years, and in the end it would wait in vain and take its heir from somewhere else entirely.

His money did not come from coal or cotton or conquest. It came from the oldest and quietest source of wealth in the world: owning the land that everyone else had to pay to stand upon. The size of the fortune has to be laid out plainly, because the size of it is not decoration in this story. It is the reason the missing son mattered so much.

The Grosvenor estate in the heart of London was, and remains today, one of the most valuable pieces of private property anywhere on earth. Bendor held the ground beneath Belgravia, the cream-colored terraces around Belgrave Square and Eaton Square, addresses so grand that to live there was itself a statement of rank. He held much of Mayfair, the streets between Hyde Park and Bond Street where the embassies stood and the great hotels rose. He held broad stretches of Pimlico.

The rent from that ground came in without labor, without risk, without a single hour of his attention. He owned the floor of the richest square mile in the country, and the world paid him for the use of it day after day, decade upon decade, the sums swelling as London itself swelled around his holdings. A factory can burn down. A ship can sink.

A business can be undone by a clever rival or a bad season or a shift in fashion. Ground rent in the center of London did none of those things. It simply accrued, lease upon lease, tenant upon tenant, the great families and the embassies and the shopkeepers all paying year after year for the right to occupy land the Grosvenors had held since before any of them arrived. Bendor did not have to be shrewd to stay rich.

He had to do nothing at all. It is a strange soil to grow a character in, and it grew in him exactly the character one might expect: a man who assumed the world would provide. The scale of that provision is hard to hold in the mind, so it is worth gathering the numbers into one place. The freehold of much of Mayfair, Belgravia, and Pimlico.

More than a hundred and thirty thousand acres across Britain. A country palace of fifty-four bedrooms, with eleven thousand acres of park around it. A deer forest in the far north of Scotland. A great hunting estate in the south of France.

Two oceangoing yachts, one of them among the largest afloat in the world, the Cutty Sark and the Flying Cloud, a black-hulled schooner of some eighty-six meters, among the largest private sailing vessels in the world. Old masters by Rembrandt and Goya and Velázquez and Rubens hung on the walls of a single house. Put beside the wage of a working man of the time, a few pounds a week if he was fortunate, the wealth becomes almost impossible to picture. Bendor never had to think about the cost of anything.

And a man who never thinks about cost slowly loses the ability to think about limits at all. He kept a mansion called Grosvenor House on Park Lane in London, one of the grandest private residences in the capital. He kept the deer forest at Lochmore in the far north of Scotland, thousands of acres of deer country in Sutherland. He kept a château in France near Rouen, and in the pine forests of the Landes between Bordeaux and Biarritz, the great hunting estate of Mimizan, where he chased wild boar with his friends across a vast sporting ground.

By almost every reckoning of the age, Hugh Grosvenor was the richest man in Britain and stood among the richest in the world. There was quite literally no comfort he could be told he could not afford. He could be strikingly generous, and often was. On his Pimlico ground, he granted long leases to build homes for working families at rents so small they were almost a joke: a single pound a year in one case, a shilling in another, so that hundreds of ordinary people had somewhere to live.

Giving on that scale cost him nothing he could feel, because the rest of the river of rent kept flowing regardless. Generosity was easy. It asked nothing of him. The hard thing, the thing that costs a person something real, is to be refused and to bear it.

And that lesson the rent never taught him, because the rent never refused him anything. Every want he had ever formed had been met almost before he finished forming it. He had never in his life been made to wait for a thing he desired, never been told that a door was closed to him, never once run up against a limit that money and rank could not dissolve. It made him charming, the ease of a man who has never had to fight for anything.

It also left him without the one muscle that ordinary life builds in everyone else: the muscle that lets a person survive being told no. And that missing muscle would matter enormously when the great refusals of his life finally came. Yet at the dead center of all this abundance sat a single absence that no amount of money could fill. It was a son.

The entail wanted an heir of his body, and for all the acres and all the rent and all the paintings on all the walls, the one thing the estate most required was the one thing he would spend his life failing to produce. He did not think about that often. Not yet. He was too busy having everything.

But the clause was there in the settlement, waiting, patient as stone. And the first attempt to answer it was already close at hand, in the person of a celebrated young beauty he was about to marry. On the sixteenth of February, 1901, Bendor married Constance Edwina Cornwallis-West, known to everyone as Sheila. She was one of the celebrated beauties of the age, born in May of 1877 at Ruthin Castle in Denbighshire, Wales, the youngest child of Colonel William Cornwallis-West, a member of Parliament and lord lieutenant of his county, and his wife, an Irish woman of famous beauty known to all of fashionable London simply as Patsy.

The Cornwallis-West daughters were bred for brilliant marriages and they made them. Sheila’s sister became Daisy, Princess of Pless, mistress of one of the great houses of Imperial Germany. Her brother, George Cornwallis-West, married the widowed mother of Winston Churchill, the famous Jennie, so that the young officer Bendor had befriended on the veldt was now bound to him by marriage as well as by war. It was a small, glittering, tightly interlaced world, in which the same few dozen families married and remarried one another across a single generation, and Bendor and Sheila stood near the very middle of it, young and rich and admired.

In the arithmetic of the aristocracy, a marriage was not only a matter of love, and often not chiefly a matter of love. It was an alliance and a transaction, and above all a means of continuation: the mechanism by which one great family produced the heir who would carry its name and its lands into the next generation. On every count, Sheila was the ideal bride. She was beautiful, superbly connected, of the right rank and the right world.

And above all, she promised an heir. Within a few years, she had given him one, though a daughter came first. Lady Ursula Mary Olivia Grosvenor was born in 1902, and she was loved and welcomed. But by the pitiless law of the entail, she could inherit nothing at all.

A daughter could not carry the dukedom. A daughter could not hold the ground beneath Mayfair. The whole enormous hope of the family narrowed again to a single point: the birth of a boy. On the sixteenth of November, 1904, that boy arrived.

He was christened Edward George Hugh Grosvenor, and from the cradle he carried the courtesy title of Earl Grosvenor, the mark of the heir apparent, the name that said plainly to all the world that here was the future of the house. It is difficult across the distance of more than a century to feel how much weight rested on that one small child. Edward was not merely a beloved son, though he was that. He was the future of the greatest private fortune in the country made flesh, the guarantee that the rent and the acres and the paintings would pass in an unbroken line.

Every great house in England understood exactly what a boy in that cradle meant. It meant the dynasty was safe. It meant the low, constant dread of the line running dry could be set aside for a generation. The richest man in Britain had done the one thing his fortune could not do for him.

He had made an heir. For those few years the picture was complete: the fortune vast beyond ordinary imagining, the beautiful well-connected wife, the little Earl Grosvenor growing in the nurseries of Eaton Hall, and behind him a sister. Photographs of the period show a golden family at the top of a golden age, the last long Edwardian summer before the Great War came to break it apart. Bendor was young, decorated, immensely rich, a husband and a father, the master of a line that would clearly continue.

But the marriage was already carrying its own quiet strains beneath the golden surface. Bendor was restless by nature, a man who consumed pleasures and experiences and moved on. Sheila was spirited and admired, and not inclined to sit quietly at Eaton while her husband ranged across his acres and his amusements. In a marriage between two such people, held together in its early years chiefly by rank and by the child, there were pressures that a single grief could crack wide open.

For a handful of years at the start of the century, the greatest private fortune in England had a small boy at the center of it, and the whole vast structure of the estate seemed entirely secure. Little Edward, Earl Grosvenor, running in the nurseries and gardens of Eaton Hall, was the sole male heir to more than a hundred and thirty thousand acres, to the freehold of half of Mayfair and Belgravia, to a house of fifty-four bedrooms hung with the work of Rembrandt and Goya, to yachts and hunting forests and a river of London rent that flowed without end. Everything the eye could see across the Cheshire park, and a great deal it could not see in London and Scotland and France, was one day meant to be his. He was perhaps the most richly promised child in the country.

The wiser families of that world knew never to rest on a single son. In the years before modern medicine, childhood was a dangerous passage even for the richest. Fevers, infections, the sudden illnesses that no fortune could turn aside—all of them took the young without regard to rank. That is why the old families spoke half grimly and half practically of an heir and a spare, because they had learned across generations that one boy was a thread and two were a rope.

Bendor had a thread and no rope. He had exactly one son, and behind him only daughters, and daughters could not inherit. The whole vast future of the house hung on the continued health of a single small boy, with nothing held in reserve. In the early spring of 1909, the heir to the greatest fortune in Britain fell ill in a nursery at Eaton Hall, and within a few days he was dead.

It was appendicitis, sudden and savage, in an age before such a thing could be reliably treated, before the drugs and the surgery that would later make it a routine trouble of childhood. In that winter, it was still a killer: the inflamed appendix, the operation attempted against it, the infection that could follow, all of it lay at the very edge of what the medicine of the time could manage. And for a small boy, the odds were cruel. On the thirteenth of February, 1909, Edward George Hugh Grosvenor, Earl Grosvenor, died.

He was four years old. There is a particular cruelty in the manner of it, because appendicitis is exactly the kind of death that money was supposed to prevent. It was a sudden, treatable, survivable thing, and only a few years later it would be survived routinely. Edward had the finest doctors in the country, the best that limitless wealth could summon, and it made no difference at all, because in that particular winter the surgery and the care that could have saved him were still just out of reach.

A poor child and the richest child in England died of the same thing that year. The heir to more than a hundred and thirty thousand acres, to half of Mayfair and Belgravia, to Eaton Hall and its Rembrandts and its yachts and its rivers of rent, was carried out of a nursery in a coffin small enough for one man to bear. There was no second son, no spare heir waiting in another cradle, no cushion of any kind. There was one child, and death had taken him.

And in a few February days, the future that had looked so complete simply collapsed inward on itself. For Bendor, it was not only the grief that any father knows, though it was certainly that. It was the failure of his entire purpose as the holder of the estate. A duke exists, in the brutal logic of the entail, to pass the line on, to be the living bridge between the generation that came before and the generation that comes after.

He had built that bridge once, in the person of his son, and death had torn it down. Now he was back exactly where he had started at the age of twenty: a man with an enormous fortune and no one of his own body to leave it to. The difference was that he was no longer twenty. The clock that governs every man’s fertility had begun quietly to run against him.

What happened around the deathbed poisoned everything that came after it. By the accounts that survive, Sheila was away when the child sickened and died, absent from Eaton at the crucial hour. And in his grief and his fury, Bendor turned on his wife. He accused her, it is said, of neglecting their son, of being off in the company of other men while the boy lay dying.

Whether that accusation was fair is impossible to know at this distance, and it should be treated as what it was: the bitter charge of a devastated man against a wife he was already half estranged from, not a settled fact of history. What is documented is that Sheila did not attend the boy’s funeral. Mother and father, already drifting apart, were driven by the death of their only son violently apart, each blaming the other or unable to bear the sight of the other. There is a detail that fixes the loss in stone, quite literally, and it is the most eloquent thing Bendor ever did.

He could not bring his son back, but he could do the thing that great wealth does with grief: he could build. He commissioned a memorial to the boy. He set the young architect Detmar Blow to design it, with the sculptor Emil Meline to carve it, and the finished monument was completed in 1910 and placed at the grave in the churchyard of the little church at Eccleston, close to the gates of Eaton Hall. It stands there still, a stone memorial to a four-year-old boy on ground within sight of the great house he would have inherited.

Of all the things the richest man in Britain ever built, that small memorial to Edward is the one that says the most, because it marks the exact place where his fortune met the limit of its power. After the death of the boy, there was one more child. Lady Mary Constance Grosvenor was born in the summer of 1910, a little over a year after her brother died. She lived a long life and became in time a spirited woman who drove fast cars and rally cars.

But she was a daughter, and a daughter could carry nothing forward. Two daughters now survived, Ursula and Mary. The son did not. The parents separated in 1913.

Sheila’s name was linked with the Duke of Alba, a Spanish grandee of the highest rank, and Bendor pursued his own restless, nocturnal life. Then the Great War came in 1914, and it gave Sheila her finest hour. She threw herself into the war effort with real energy and organization, sponsoring and running a military hospital at Le Touquet on the French coast, housed in a requisitioned casino, tending the wounded of the Western Front within sound of the guns. In 1918, she was appointed a Commander of the Order of the British Empire for her service.

The wife Bendor would blame and cast off had run a hospital through the greatest war the world had yet seen and been decorated by her country for it. The formal end of the marriage came after the war, on the nineteenth of December, 1919. In the convention of the time, it was the husband who took the public blame for the breakdown, and Bendor followed the convention. The divorce was granted on the grounds of his own adultery and desertion.

He took the blame so that his wife need not carry it. Then he sealed the arrangement with the largest settlement English law had ever recorded: an income for Sheila of thirteen thousand pounds a year, a sum worth well over half a million in the money of today, reported at the time as the largest such settlement in the whole history of English law. The money simply was not the point, because the money never ran out and never could. There is a strange grace note to the ending.

Having blamed her, separated from her, divorced her, and paid her that record sum, Bendor then settled into something almost like friendship with the woman he had cast off. In the years that followed, he and Sheila were on cordial terms again, seen together at the great occasions of their daughters’ lives, jointly hosting the coming-out balls by which Ursula and Mary were launched into society. Sheila herself lived on for another half century after their marriage ended, dying at last in 1970 at the age of ninety-two, long after the man who had married her and blamed her and paid her that record sum was in his own grave. But in 1919, freshly and expensively single, Bendor was a man in his early forties with the same hole at the center of his life.

The entail was exactly as hungry as it had been on the day he came into the estate, and every year that passed was a year gone from the span in which he might still make another son. Within the year, he would marry again. Her name was Violet Mary Nelson. She had been born in 1891 in Liverpool, the daughter of a baronet, Sir William Nelson, and she came to Bendor with a first marriage already behind her, to a man named George Rowley, whom she had married in the spring of 1914 and divorced in 1920.

Freshly free, she married Bendor on the twenty-sixth of November, 1920, only months after her own divorce was finalized and only months after his. On paper, it answered the requirement. In practice, it answered nothing at all. The marriage gave him no children, no son, no heir.

It drifted and foundered, and by 1926, after some six years, it was quietly dissolved. Violet was the second name on a list that would run to four, and of the four, she is the faintest. Within a year of her divorce from Bendor, she had married again, taking as her third husband a naval officer, Lieutenant Commander Frederick Cripps, and passing out of the Grosvenor story into a life of her own. She lived on until 1983.

But the timing of that second marriage matters far more than its emptiness, because of what was happening in Bendor’s life in the very years it was falling apart. While Violet was still in law his wife, Bendor met and fell for a French woman who had built her own fortune from nothing and had not the smallest intention of dissolving it into his. Her name was Gabrielle Chanel, and the world knew her as Coco. She was introduced to him in Monte Carlo over the winter of 1923 and into 1924: a small, sharp-eyed, plainly dressed French woman who had come up from nothing and built an empire on her own name.

He was in his middle forties. She was near forty. She was the opposite of him in every way that mattered. He had been handed a fortune at birth and had built nothing.

She had been born poor and had built everything she owned with her own two hands. By the time Bendor met her, she commanded her own house of couture, her own perfume that sold around the world, her own money and her own bank, her own name above her own door. In an age that expected a woman of her low birth to end as a servant or as some rich man’s kept mistress, she had made herself a genuine power. Bendor courted her on the only scale he knew, the scale of pure abundance.

He swept her aboard the black-hulled schooner, the Flying Cloud, and they cruised the Mediterranean and the Atlantic together. He brought her north to the salmon rivers of Scotland and south to the boar hunts of Mimizan, where even Winston Churchill, staying with his old friend, met the famous dressmaker and sent home warm reports of her, calling her impressive company. Bendor gave her ropes of natural pearls and loose emeralds and a painting by a French master. In 1927, he gave her a parcel of land on the hills above the Riviera at Roquebrune, and on it she built a white villa she called La Pausa, designing it herself down to the last detail.

Across the years of the affair, the biographers reckon his total outlay on her ran into the modern equivalent of tens of millions of pounds. He asked her to marry him, and he proposed more than once across the years of the affair, and each time she refused. He was not asking only for love. He was asking her to solve the great problem of his existence.

He had buried his only son. Two marriages had given him no other. Here was a woman he adored, and if she would marry him and give him a boy, the long anxiety of the entail would be answered at last. The friend who had introduced them, Vera Bate Lombardi, is said to have pressed exactly that point on him: that Chanel was nearing the end of her childbearing years, and that if he wanted a son from her, he could not afford to wait.

Still she said no. Not in a single dramatic scene, but steadily, finally, across years. To marry him, she would have had to become his: ranked by his rank, housed in his houses, named by his name. And she had spent her whole life making certain she would never again be defined by anyone.

To become the Duchess of Westminster, she would have had to stop being Coco Chanel, and being Coco Chanel was the only thing she had ever truly owned. Her refusal is remembered fittingly in a single perfect sentence that she may never actually have spoken. “There have been several Duchesses of Westminster,” she is supposed to have said, “but there is only one Chanel. ” It is too good a line, and in her old age she is reported to have denied ever saying it, and her careful biographers have suggested it more likely grew out of a compliment paid to her across a lunch table by a diplomat in Paris.

And it does not matter in the least, because it is true whoever first said it. There were several duchesses. Bendor married four women across his life, and not one of them was Chanel. There is a century on, still only one Chanel.

The affair wound down around 1930 after roughly six years, ending not in a rupture, but in the slow recognition that the answer would always be no. It left Bendor past fifty now, having loved the one woman he could not have, and in loving her, having passed the years in which he might most easily have made an heir with someone else. Barely five months after Coco Chanel refused him for the last time, the Duke of Westminster married a duchess of the proper English kind, with Winston Churchill standing at his shoulder as best man. On the twentieth of February, 1930, Bendor took as his third wife Loelia Mary Ponsonby, and the wedding was the society event of the season.

Loelia had been born in February of 1902, the only daughter of Sir Frederick Ponsonby, a courtier so close to the crown that he served three sovereigns in turn and was raised in time to the peerage as Baron Sysonby. She had grown up inside the royal household world, at the very center of English court society. She knew how to move through a palace, how to manage a great house, how to be a duchess in a way that a self-made French woman from a convent orphanage never would have consented to learn. She was, in that sense, the anti-Chanel: the woman built by her upbringing to be exactly what the French woman had refused to become.

When she married Bendor, she was twenty-eight years old. He was fifty-one, twice divorced, immensely rich, and freshly wounded by the greatest refusal of his life. The wedding itself was a spectacle worthy of the fortune behind it, and that Churchill agreed to stand as best man tells you how deep the friendship between the two men ran. The man who had watched the great love affair at close quarters now stood witness to its hurried public replacement.

The marriage, in its bones, was a papering over. Bendor had asked the one woman he truly wanted, and she had refused him. Rather than sit with that refusal, he reached at once for the nearest acceptable thing. Loelia could be had.

She was young, well-born, suitable in every way that Chanel had refused to be. The new Duchess of Westminster stepped into a role that had been, in the Duke’s own heart, offered first to a French woman who turned it down flat. She was living inside an absence. It is a difficult foundation to build a marriage on.

By the account of the woman who lived it, life as the third Duchess of Westminster was a gilded restlessness beside a man who could not be still and could not be pleased. Loelia left a record, which is more than the other wives did. Her memoir, published in 1961 under the title Grace and Favor, with a foreword by Noël Coward, is the voice of a woman looking back on the union across thirty years. It must be read as exactly that, the partial, wounded retrospective account of an unhappy wife, and not as a neutral history.

With that caution held firmly in place, it remains a remarkable document. The life was one of ceaseless movement, a restless circuit between the great houses and the yachts and the continental estates that never settled anywhere long enough to become a home. There was Eaton Hall in Cheshire, and the Scottish lodge in the far north, and the places in France, and the vessels on the sea. The household moved among them at the Duke’s restless will, packing and unpacking, arriving and departing, forever in motion, and forever somehow arriving nowhere.

By her account, it was a kind of luxurious imprisonment, a life with no fixed center of its own, ruled entirely by the moods and the whims of a man who was himself always looking for the next place. Bendor was by this stage of his life a difficult man, and growing steadily more difficult. The easy golden charm of his youth had begun to thicken into something heavier and darker, a restlessness that curdled into suspicion, a temper that could turn without warning and leave a whole household walking on eggshells. Others saw it from outside and put it more harshly than she ever allowed herself to in print.

The diarist James Lees-Milne, who moved through the same aristocratic world and observed its marriages with a cold, clear eye, described the union of Bendor and Loelia as “a definition of unadulterated hell. ” It is a phrase that has clung to the marriage ever since, and nothing in Loelia’s own memoir works to contradict it. And through it all ran the same failure that had shadowed every marriage before it. Loelia and Bendor had no children.

By her own account, they were unable to have them. And so the third marriage, like the second, gave the estate nothing. Bendor and Loelia drifted into separation, living apart for years, while the marriage remained in law unbroken. The formal divorce, when it finally came, would not arrive until 1947, seventeen long years after that glittering wedding, and by then the marriage had been a dead thing in all but law for the better part of two decades.

It was in exactly those years, as the third marriage curdled and the estate stayed heirless, that the darkness in Bendor stopped being merely a matter of temper and moods, and turned into something uglier. The easy charm that had carried him through the first half of his life thickened in the second half into something heavier, more suspicious, and at last genuinely ugly. He drank. He grew suspicious and difficult, prone to dark moods and long grudges that he nursed for years.

The brilliant friends of his youth fell away, or were driven off by his temper and his suspicion, and the glittering circle that had once revolved around him thinned year by year. And in these years, his decline took a turn that no honest account of his life can pass over or excuse. Bendor drifted into open sympathy with Nazi Germany. He moved in the circles that argued for friendship with Hitler’s regime and against another war with it, and his private views carried a real and documented streak of anti-Semitism.

This is not a matter of interpretation or rumor or a single unguarded remark. It is part of the settled record of the man, and it is indefensible. In the 1930s, a strand of the British aristocracy looked across at Germany and saw not a gathering horror, but a bulwark against communism and a partner Britain might do business with. Bendor moved among them and shared their views, and carried besides a personal anti-Semitism that the record does not let us pretend away.

None of that belongs to the story of the marriages, and it should not be allowed to bleed into it. A man can fail at fatherhood and fail at decency both, and the two failures are separate. But the darkening politics and the darkening private man ran side by side through the same lonely years. Through the whole of this long darkening, the estate stayed heirless.

Bendor was in his fifties now, and then approaching sixty, and the boy the entail demanded had never been born to any of his marriages. His third marriage was dead in all but law. His politics had carried him into disgrace among decent people. His friends had thinned to a handful.

And still, incredibly, he had not finished marrying. In 1947, the long-dead union with Loelia was at last dissolved by divorce, seventeen years after that glittering wedding of the season. And in the very same year, on the seventh of February, 1947, the Duke of Westminster, now sixty-seven years old, married again. His fourth and final wife was Anne Winifred Sullivan, known to those close to her as Nancy, and she was thirty-one years old.

She was younger than his own surviving children. His daughter Ursula had been born in 1902, and his daughter Mary in 1910, which made both of them older than the woman their father was now taking as his wife and duchess. He was marrying a woman five years younger than his own youngest child, a woman who might have been his granddaughter, and he was doing it in his sixty-eighth year. Anne had been born in April of 1915 at Glanmire in County Cork, Ireland, the daughter of a brigadier general, and she had brothers, one of whom, Adam, was killed in the fighting in Norway in 1940 during the war.

She was young, and by all accounts a fine and spirited woman with a great love of horses and the country. She married a man who was near the end of a long and complicated and increasingly lonely life. What the record says plainly and without exception is the one thing that matters most to this story: the fourth marriage, like the third, and like the second before it, produced no children. There was no son.

There was no heir. Set the four marriages side by side and the pattern is complete and merciless. The first had given him a son, and then taken the boy away, and ended in the largest divorce England had ever seen. The second had given him nothing at all, and ended quietly after six empty years.

The third had given him nothing but a great deal of misery, and ended in a long separation and a late divorce. The fourth, made to a woman younger than his own daughters, gave him nothing, and would end only with his death. When he died at last on a Scottish moor in the summer of 1953, the taxman came for his estate on a scale that had never been seen before in England. Hugh Grosvenor, second Duke of Westminster, the boy named after a racehorse, the richest man in Britain, died on the nineteenth of July, 1953, at Lochmore, his shooting lodge in the deer country of Sutherland in the far north of Scotland.

His heart gave out, a coronary thrombosis, quick and final. He was seventy-four years old. He died not in a London mansion or the great state apartments of Eaton, but in a shooting lodge on a remote Scottish moor in the deer forest that had been one of his favorite retreats. Winston Churchill, the young officer he had met on the veldt more than half a century before, outlived him, still at the center of the nation’s affairs.

The death duties levied on his estate came to around eighteen million pounds, an almost unimaginable figure for the time, the largest such bill the country had yet seen fall on a single estate. It was so vast that the family could not simply pay it out of hand. The settling of it stretched on for eleven years, the final installment handed over to the revenue in 1964, more than a decade after Bendor was in his grave. The Grosvenor estate was rich enough to survive the blow and go on.

But the very size of the duty is a measure of how the age had turned. The wealth had been a river all his life, and it was a river still, only now it ran the other way. When the accountants had finished their sums, there remained the one question that had ruled Bendor’s whole life, and that no sum of money could answer. Who would inherit the title?

With no surviving son of his body, the dukedom that Bendor had married four times to keep in his own blood slid sideways at his death and passed to a cousin. William Grosvenor became the third Duke of Westminster. The title, the entailed estate, the great inheritance that Bendor had spent his whole life trying to pass to a son of his own, went to a man who was not his son, not his grandson, not of his direct line at all, but a relative from a side branch of the family who happened to stand next in the male succession. Think for a moment of what that sideways step erased.

The whole point of an entail was to keep the great inheritance running down through a man’s own children, the blood and the fortune traveling together through the generations in an unbroken line. Bendor’s blood did not travel with the fortune. The second Duke had two living daughters, and the very law he lived under would not let a daughter carry the name or hold the ground. Ursula and Mary were Bendor’s own children, of his own blood, alive and grown at his death, and under the rule that governed the great estate, they might as well, for the purposes of the succession, never have existed at all.

The title could not come to them. The entailed lands could not come to them. A cousin they may barely have known stepped past them to take the dukedom and the heart of the fortune. What could be left to them privately was left, and it was not nothing: his fourth wife Anne would come to hold, alongside his daughter Lady Mary, some hundred and twenty thousand Scottish acres that lay outside the strict entail.

But the name, the title, the great inheritance at the center of it all, passed clean over his own daughters to a man of the male line, exactly as the rule required. And so the small grave at Eccleston takes on its final and heaviest meaning. Edward, Earl Grosvenor, dead at four years old in 1909, turned out to be not merely the first heir Bendor lost, but the last direct heir he would ever have. Everything that came after, all four decades of it, all four marriages, and the great refusal in between, was an attempt to replace that one small boy.

And none of it worked. The child under the stone remained to the very end, and beyond it, the only son the second Duke of Westminster would ever make. When Bendor’s life ended, the title simply stepped over the empty nursery and went to a cousin, exactly as it would have done if he had never fathered a son at all. The Grosvenor fortune remains to this day one of the great private land holdings in Britain, and the dukedom of Westminster continues still, carried down the years from that cousin who inherited it when Bendor died.

The rent of Mayfair and Belgravia still flows, as it has for centuries. The name still stands among the grandest in the country. But it flows and it stands along a line that stepped around Bendor rather than through him. The estate got its future and its long continuation.

Bendor did not get to be the road it traveled. Of the four women he married in his long chase after an heir, three outlived him, and every one of them proved to have a full and separate life that the second Duke of Westminster was only ever one chapter of. Sheila, the first wife, the one who had given him the son and then been blamed for the boy’s death, lived the longest of them all. She remarried within weeks of the decree, went on, cordial in the end, even with the man who had cast her off, to see her two daughters launched into society at balls she and Bendor hosted together.

She lived until 1970, dying at the great age of ninety-two, seventeen years after Bendor himself was in his grave. Violet, the second wife, did not linger in the wreckage either. Within a year of her divorce from Bendor, she had married again, her third husband, a naval officer, and she passed clean out of the Grosvenor story into a long life of her own. She died in 1983.

Loelia, the third wife, the witness to the unadulterated hell, made perhaps the fullest second life of them all. After the long-dead marriage was finally dissolved in 1947, she went on for decades more. In 1969, she married again, becoming the wife of the explorer Sir Martin Lindsay. She wrote her memoir, Grace and Favor, that preserved forever the inside of those unhappy years.

She lived until 1993, more than sixty years after that glittering wedding of the season, and forty years after the death of the man whose moods and restlessness had once ruled the ceaseless circuit of houses she had been trapped inside. And Anne, the fourth and last wife, was widowed at the age of thirty-eight when Bendor died in 1953, and she went on to live another half century entirely without him. She retired to a house on the Eaton estate and stayed there for fifty years. She became a celebrated figure in the world of horse racing, the owner in time of the great steeplechaser Arkle, one of the most beloved and famous racehorses in the entire history of the sport.

She died in 2003, fifty years a widow, remembered in her own right for the horses she owned and loved. The two daughters too lived on beyond him. Ursula, the elder, born in the first years of the marriage that had begun it all, lived until 1978. Mary, the younger, born in the shadow of her brother’s death, grew into a spirited woman with a passion for fast cars and the racing life, and she lived until the year 2000, dying at the very edge of a new century, ninety years after she was born into the old one.

Gather the whole company of them together—the four wives and the two daughters—and the shape of the story shifts one final time. Six women stood in the orbit of the second Duke of Westminster across his life, and every one of them in her own way outlived the thing he cared about most. The wives walked out of their marriages into full lives of their own. The daughters, barred from the succession by the accident of their sex, lived long and well regardless.

It was the man himself, and the fixed idea at the center of him, that came to nothing. The women lived. The line did not. He could buy a castle of fifty-four bedrooms, two oceangoing yachts, a hunting forest in France, and a parcel of the Riviera for a woman who would not marry him.

And he could not buy or marry or inherit his way to the single thing his own title demanded of him, which was a living son. That is the whole story, compressed into one hard fact. So return at the last to where the story began: to the churchyard at Eccleston, a short walk from the gates of the great house, where a small stone memorial stands over the grave of a boy who died at four years old. His father commissioned it in the first raw year of his grief, and set the finest hands he could hire to design and carve it.

And it has stood there now for more than a century, on ground within sight of the palace the boy would one day have inherited. Around it, the whole Grosvenor fortune rolled on into the hands of a cousin and down the years to dukes who came after. The rent still flowing, the name still grand, the estate still one of the greatest in the land. But the child under the stone never moved from where his father laid him, and he never stopped being what he had been from the moment he died: the only son the second Duke of Westminster would ever have.

The richest man in Britain could buy anything the world had for sale, and there was almost nothing the world would not sell him. He went to his own grave at Eccleston, close by the small stone he had raised, having learned the one lesson his fortune had spared him all his life until the end: that the thing he wanted most had never, for a single moment, been for sale at all.
