France, 1915. Europe was tearing itself apart in the trenches. Millions of men had vanished at the front. Letters were slow. Military files piled up. And in that France where absence had become routine, a small, bald man with a neatly trimmed beard and correct manners was clipping matrimonial advertisements, writing letters under borrowed names and recording the expenses of his appointments in a small notebook. His name was Henri Désiré Landru. And his method was, in essence, hope turned into a trap.
Landru was tried in Versailles between 7 and 30 November 1921 and sentenced to death for eleven murders: ten women and the teenage son of one of them. He never confessed. And that refusal, maintained until the guillotine, made the case even more disturbing. Because Landru was not caught beside a body. He was caught beside a sum of absences. The Bluebeard was the nickname. The file was something else entirely.
Case File
To understand Landru, you need to understand wartime France. Between 1914 and 1918 the country endured a human devastation without modern precedent. Men went to the front and did not always return. Letters were slow, rumours grew and silence settled into homes. Women held together what remained: work, children, debts, uncertain grief.
Landru did not operate outside that context. He operated inside it with repugnant precision. His victims were not strangers chosen at random from a street. They were women who had been contacted, seduced and persuaded. He presented himself as a respectable widower, a solvent businessman, a reliable future husband. He used personal advertisements and matrimonial agencies. He adopted aliases. He promised an ordered life. And once he had gained trust, the women disappeared.
A knife kills once. A lie starts earlier and works more slowly. Landru exploited hope. He did not enter by force. He entered through the need to believe. That is what makes him especially repugnant.
Landru was born in Paris in 1869. Before becoming the Bluebeard of Gambais he was a criminal of fraud, false identities and shady deals. That detail is fundamental. As with H. H. Holmes, the murder does not stand apart from the fraud. It is an extension of it.
Landru was methodical to an extreme degree. He kept notebooks, notes, accounts, addresses, schedules, expenses and income. The Musée du Barreau de Paris highlights the importance of his carnet, described as a truly meticulous accountant's diary, with notes and dates that became essential pieces of evidence in the trial.
That notebook is the symbolic heart of the case. Other killers leave blood. Landru left bookkeeping. Names, initials, journeys, purchases, expenses, furniture sold, dates of meetings. His crime did not have the shape of an impulse. It had the shape of an administration. The banality of evil, but with a small notebook and neat handwriting.
Landru did not merely rob his victims. He absorbed them into a system. He turned them into a diary entry, an appointment, a journey, an income stream, a piece of furniture to be sold.
Landru's black notebook was the piece of evidence that carried most weight at trial. In it he had recorded the names of the women he had met, the train journeys, the expenses associated with each relationship. It was, in essence, the register of a business operation.
For several of the victims, the record showed something the prosecution was able to deploy with devastating precision: Landru had purchased return tickets to Gambais. But only one return. His. The return ticket for the woman accompanying him did not appear in the record. She simply did not come back on the train.
There is no clearer confession than an unused ticket. The notebook Landru kept to administer his crimes became the evidence the prosecution needed to build a truth without bodies.
Landru used more than ninety false names. The press called him "the man of ninety pseudonyms." An alias was his first weapon: it allowed him to make promises without carrying his past, to change identity was to change debt, history and responsibility.
For the women who responded to his advertisements, Landru could be a serious widower, a solvent businessman, a mature man in search of a home. For the police afterwards, he was a tangle of signatures, rental agreements, documents and contradictory testimony.
That is one reason why the case feels so modern. Landru understood that identity could be a criminal tool. He did not kill only with his hands. He killed with papers, names, contracts, train tickets and promises. The twentieth century had barely begun and it was already perfectly equipped for imposture.
The first was Jeanne Cuchet, forty-two years old. A widow who had been in a relationship with Landru for some time when she disappeared in January 1915 in Vernouillet. With her disappeared her son André, seventeen years old. André is the eleventh death in the conviction — the young teenager that most summaries of the case mention in passing and who deserves to be named: he was not an adult, he was a boy who was there with his mother.
Célestine Buisson disappeared in August 1917 in Gambais. She was fifty-two. Marie-Angélique Guillin, fifty-five, disappeared in August 1915. Anna Collomb, forty-four, in December 1916. Louise Jaume, thirty-six, in November 1917. Their names appear in the documented sources. Placing them here is not a formality. It is the minimum.
They were not "Landru's fiancées" as if they were romantic accessories to his legend. They were specific women — some widows, some with children, some with modest savings, some looking for a second life in a country broken by war. Responding to a matrimonial advertisement in that France was not necessarily naivety. It could be a form of emotional, economic or social survival.
Landru turned that humanity into exploitable vulnerability. The press afterwards often turned them into a list. We should do neither.
The disappearances linked to Landru centred particularly on two locations: Vernouillet and Gambais, villages close to Paris. In Gambais he rented a villa that the press turned into the central setting of the case.
The house at Gambais — known as the Villa Tric — became the French equivalent of the criminal stage set: the isolated property, the fireplace, the kitchen, the garden, the strange smells that neighbours noticed. Here, as at Road Hill House, as in the Red Barn, as in Holmes's building, the space became a character. Architecture always finds a way to collaborate with myth.
The Bibliothèque nationale de France holds press photographs of the searches conducted in April 1919 at the Gambais villa and at Landru's apartment on the rue Rochechouart in Paris. It also holds images from the 1921 trial where exhibits were shown, including the kitchen associated with the remains found there.
But the centre is not the villa. The centre is the women who entered Landru's orbit and did not return. The house matters as evidence. Not as protagonist.
One of the most disturbing aspects of the case is that no complete bodies were ever found. Calcined human remains were discovered, fragments, indications sufficient to build an accusation — but not identifiable corpses in the classical sense.
This gave Landru a constant line of defence: deny everything. He admitted fraud, theft and deception. But not the murders. He consistently acknowledged having robbed and swindled his alleged victims, but always denied having killed them.
That strategy had a technical logic. Without complete bodies, without direct witnesses to the moment of death, without a confession, the trial had to rely on accumulated circumstantial evidence: women who disappeared after contacting him, journeys documented in his notebook, belongings sold, false documents, calcined remains. The Landru case is in large part a trial of a chain of absences. Each link in isolation could be argued. Together they formed a pattern very difficult to ignore.
The trial opened in Versailles on 7 November 1921 and closed on the 30th. The public interest was enormous. It was not merely a criminal proceeding. It was a national spectacle. There were journalists, caricaturists, writers, curious onlookers, celebrities. The train that carried magistrates, police officers, witnesses and reporters from Paris to Versailles each morning became popularly known as the "train Landru."
The press found a perfect character: a cold, ironic, meticulous defendant, apparently unshakeable. The Bibliothèque nationale de France holds photographs of the public and journalists in the courtroom, as well as images of Landru answering questions, consulting notes and surrounded by exhibits.
One scene summarised the case better than any speech. When the prosecutor asked what he had done with the missing women, Landru took out his notebook, consulted it calmly and replied that he had nothing to declare on that matter. The man accused of eleven murders checking his appointments diary as if looking for a business meeting. If there is a single image that captures Landru, it is that one: the office criminal looking at his notes while the country looks at him.
Defence counsel Vincent de Moro Giafferri — already celebrated for other major trials — tried to dismantle the prosecution by insisting on the absence of complete bodies and of direct evidence of murder. As a technical line it was reasonable. A court cannot convict on the basis of revulsion alone. It must prove.
The defence tried to turn the absences into reasonable doubt. The prosecution tried to turn them into certainty. Landru forces you to think about how a series of crimes is judged when the criminal has made the elimination of bodies his principal method. The justice system had to read papers, objects, journeys, furnaces, minimal remains, false names and one-way train records. It was not pursuing a crime scene. It was pursuing an administration of death.
Landru was found guilty and sentenced to death on 30 November 1921. He was guillotined on 25 February 1922 at Saint-Pierre prison in Versailles. Until the end he maintained a defiant and ambiguous attitude. He never clearly confessed to the murders for which he was executed. He denied them to the last. And precisely for that reason his figure continued to grow after his death. Confession closes a case. Denial keeps it open. Landru died, but he left the door to the myth ajar.
The nickname Bluebeard of Gambais was a journalistic masterstroke and an interpretive trap. A masterstroke because it compressed the case into a recognisable image: the man who seduces women and makes them disappear. A trap because it turned a modern file into an ancient fairy tale.
Landru did not live in a castle but in an administrative, railway, postal and advertising France. He did not lock wives behind a forbidden door of legend — he contacted women through advertisements, took them by train, recorded expenses and sold their belongings. The fairy tale helped sell newspapers. But the file said something more modern and colder: crime had learned to use the ordinary instruments of contemporary life. Advertisements. Letters. Trains. Rental agreements. Notebooks. Furniture. Receipts. Landru was not a medieval relic. He was a criminal of the nascent twentieth century.
A fair reading of the case must always return to the victims and their context. The women who fell into Landru's net were not fairy-tale innocents. They were women living in a society torn by war, loneliness and economic uncertainty. Seeking marriage, protection, companionship or stability was not ridiculous. It was human.
Landru turned that humanity into exploitable weakness. The culpabilising tone must be avoided. Nothing of the kind of "how could they have believed him." That question is usually cowardly. The correct question is: what kind of world made a man like Landru look like a reasonable option? The answer includes war, widowhood, precarity, gender, reputation, economic dependence and loneliness.
Landru killed women. But first he read them. He read their needs. And that reading was part of the crime.
The digitisation of the Landru file by the Yvelines departmental archives encompasses some 17,000 documents linked to the judicial and police case. That is a reminder: beneath the myth there is an archive. And the archive is less spectacular but more serious.
The myth wants the Bluebeard: beard, villa, furnace, witty remarks, guillotine. The archive wants names, dates, letters, reports, testimony, receipts, records, photographs and contradictions. For Criminal Epochs this case exists on that boundary: not denying the force of the myth, because it exists and forms part of the case, but not being swept away by it either. The task is to show how it was constructed and what it conceals.
The myth makes Landru famous. The archive returns weight to the disappeared women. Jeanne Cuchet, forty-two. André Cuchet, seventeen. Marie-Angélique Guillin, fifty-five. Célestine Buisson, fifty-two. Anna Collomb, forty-four. Louise Jaume, thirty-six. Six of eleven. By name. Because the list is not a formality.
Landru still matters because he speaks to things that have not aged. He speaks of predators who use loneliness as a point of entry. Of false identities and calculated seduction. Of women made vulnerable by a society that judges before it protects. Of a press that turns a trial into theatre. Of how a war can create zones of shadow where disappearing becomes easier. Of a justice system that had to convict without complete bodies, relying on an accumulation of circumstantial evidence.
He also raises an uncomfortable question: why do certain criminals fascinate so much. Landru should not be charming. And yet his irony, his meticulousness, his refusals and his nickname turned him into a character. That transformation is dangerous. The charismatic criminal tends to occupy centre stage. The victims are left around the edges, as if summoned to explain his greatness. That narrative error must be avoided.
Landru was not great. He was efficient. And that difference matters.
The Bluebeard was the fairy tale. Landru was the file. And the file, as is usually the case, is the more frightening of the two.
