The Papin Sisters

Christine and Léa Papin; the Le Mans murders

1933 · Le Mans, France

XVII. SHARED PSYCHOSIS AND THE MANDATE TO KILL

None.

Who led it

CHRISTINE PAPIN (1905–1937) was the elder and dominant sister; LÉA PAPIN (born 1911) the younger and dependent one.

What it worshipped and taught

No doctrine. Two live-in maids, raised in institutions, almost entirely without social contact outside the household they served, who killed their employer and her daughter with extreme violence during a dispute over a domestic trifle. THE CASE IS THE CLASSIC CITATION FOR FOLIE À DEUX IN THE CRIMINAL LITERATURE, and whether it truly was one is still argued.

Who was in it

Christine and Léa Papin; MADAME LANCELIN and her daughter GENEVIÈVE, the victims; JACQUES LACAN, who wrote about the case in 1933; JEAN GENET, whose play THE MAIDS was informed by it.

How it ended, or where it stands

CHRISTINE DIED IN CONFINEMENT IN 1937. LÉA was released early, in the 1940s, and lived quietly under another name.

The dead

Two: Madame Lancelin and her daughter Geneviève.

Of note

THE MOST INSTRUCTIVE FACT IN THIS FILE IS WHAT HAPPENED WHEN THEY WERE SEPARATED, AND IT CUTS BOTH WAYS.

Christine, the primary, collapsed. She deteriorated in custody away from Léa and was dead within four years. Léa, the secondary, was released early in the 1940s and lived an unremarkable life for decades afterwards. THAT IS EXACTLY THE PATTERN ENTRY 171 DESCRIBES, and it is the reason this case became the standard example.

BUT THE DIAGNOSIS IS NOT SETTLED AND THIS FILE WILL NOT PRETEND OTHERWISE. Contemporary court psychiatrists found both women sane and responsible. Later writers have variously read the case as folie à deux, as Christine's psychosis with Léa merely dominated, as class violence, and as a story the French intelligentsia found useful. THE EVIDENCE SUPPORTS THE PRIMARY-SECONDARY STRUCTURE. It does not settle whether Léa shared a delusion or simply obeyed her sister, AND THOSE ARE DIFFERENT THINGS with different moral weight.

ONE CAUTION ABOUT THE LITERATURE. This case has been written about by more famous people than almost any other crime of its century, and a great deal of what is repeated about the sisters' inner lives is inference by novelists and theorists rather than record. THE DOCUMENTED FACTS ARE THE KILLINGS, THE SENTENCES, THE SEPARATION AND CHRISTINE'S DECLINE. Most of the rest is interpretation, and it should be read as such.

Its timeline

Before 1933 The sisters, from a poor and institutional background, work together as live-in maids for the Lancelin family. They keep almost exclusively to each other's company.
2 FEBRUARY 1933 AFTER A DISPUTE OVER A MINOR DOMESTIC ACCIDENT, THEY KILL MADAME LANCELIN AND HER DAUGHTER GENEVIÈVE. The violence was extreme and included mutilation of the victims' eyes. The sisters were found together afterwards, in one bed, and admitted what they had done immediately.
1933 The case becomes a national sensation and is read politically — as class violence, as the revenge of servants — as much as psychiatrically. Court-appointed psychiatrists find them sane; the defence disagrees.
28–29 SEPTEMBER 1933 The trial at Le Mans lasts a single day. The jury deliberates for about FORTY MINUTES. CHRISTINE IS SENTENCED TO DEATH BY GUILLOTINE. LÉA RECEIVES TEN YEARS' HARD LABOUR as an accomplice — the sentencing itself encodes the primary and secondary structure.
1933 JACQUES LACAN publishes MOTIFS DU CRIME PARANOÏAQUE: LE CRIME DES SŒURS PAPIN in the review MINOTAURE, treating it as paranoid crime; it enters French intellectual life permanently.
22 JANUARY 1934 PRESIDENT ALBERT LEBRUN commutes Christine's death sentence to life with hard labour. She had refused to sign her own appeal for clemency.
25 MAY 1934 Christine is moved from prison in Rennes to the SAINT-MÉEN asylum.
18 MAY 1937 CHRISTINE DIES IN THE SAINT-MÉEN ASYLUM AT RENNES, AGED 32. She had deteriorated severely after being separated from her sister and had refused food; the cause recorded is a lung illness brought on by malnutrition. She is buried in a common grave.
1941 or 1943 LÉA IS RELEASED EARLY. English and French sources disagree on the year and this file does not pick one.

Its people

Christine Papin

—

Maid; the primary in the Le Mans killings · 8 March 1905 – 18 May 1937 · active 1933–1937

The elder Papin sister and, on the evidence of the sentencing and of what happened afterwards, the dominant one. Raised largely in institutions and in domestic service, she and her sister worked as live-in maids for the Lancelin household in Le Mans and kept almost exclusively to each other. On 2 FEBRUARY 1933 the two of them killed MADAME LANCELIN and her daughter GENEVIÈVE with extreme violence during a dispute over a household trifle. Christine admitted it at once. Court-appointed psychiatrists found her sane and responsible; the defence disagreed; the argument has never closed.

Before the law. Convicted of murder 29 September 1933; death sentence commuted to life; died in confinement 1937.

Where things stand. Deceased. HER COLLAPSE AFTER SEPARATION IS WHY THIS CASE BECAME THE STANDARD EXAMPLE, AND IT IS ALSO WHY THE STANDARD READING IS UNCOMFORTABLE. Entry 171 predicts that the SECONDARY tends to improve when separated and the PRIMARY does not. Léa served her time and lived quietly for decades; Christine was dead within four years. THE PREDICTION HELD. What it does not settle is whether Léa shared a delusion or simply obeyed her sister, and those are different things carrying different moral weight.

1905 Born in Le Mans.
2 FEBRUARY 1933 The killings. The sisters are found together afterwards in one bed and confess immediately.
29 SEPTEMBER 1933 SENTENCED TO DEATH BY GUILLOTINE.
22 JANUARY 1934 The sentence is commuted to life with hard labour by PRESIDENT ALBERT LEBRUN.
1933–1937 DETERIORATES SEVERELY IN CONFINEMENT AFTER BEING SEPARATED FROM LÉA.
18 MAY 1937 Dies in an asylum, probably as a result of refusing food.

Léa Papin

—

Maid; the secondary in the Le Mans killings · 15 September 1911 – 24 July 2001 (contested; see status) · active 1933–2001

The younger sister, sentenced as an accomplice rather than as a principal. She served her term, was released, and lived under another name working as a domestic servant. SHE NEVER SPOKE PUBLICLY ABOUT THE CASE.

Before the law. Convicted as an accomplice 30 September 1933; ten years' hard labour; served and released.

Where things stand. DECEASED, BUT THE DATE IS GENUINELY DISPUTED AND THIS FILE WILL NOT PICK ONE. The long-standing account gives 1982. Ventura's 2000 documentary asserts she was alive until 24 July 2001. THE WOMAN IN THE FILM COULD NOT SPEAK, which is precisely why the identification cannot be settled from the outside. What the dispute demonstrates is the thing entry 172 warns about: this case has been written about by more famous people than almost any crime of its century, AND EVEN THE DEATH DATE OF ONE OF ITS TWO PRINCIPALS IS AN ARTEFACT OF SOMEBODY'S BOOK OR FILM RATHER THAN OF A RECORD.

1911 Born in Le Mans.
2 FEBRUARY 1933 Takes part in the killings.
29 SEPTEMBER 1933 SENTENCED TO TEN YEARS OF HARD LABOUR AS AN ACCOMPLICE — the sentencing itself encodes the primary-and-secondary structure the psychiatrists were arguing about.
1940s onward Released; lives quietly under another name.
1982 Widely reported to have died.
2000 THE FRENCH FILM-MAKER CLAUDE VENTURA, MAKING EN QUÊTE DES SOEURS PAPIN, SAYS HE HAS FOUND HER ALIVE IN A HOSPICE — partly paralysed by a stroke and unable to speak, and therefore unable to confirm or deny who she was.
24 JULY 2001 The woman in the film dies and is buried beside the Papin sisters' mother.
