Blanche Monnier: The Woman Who was Locked Away for 25 Years

In May 1901, the Paris Attorney General received an anonymous letter describing the ghoulish events of a house in Poitiers, France. According to the scribbled text, a woman had been held captive under horrific conditions at 21 rue de la Visitation for a quarter of a century.

The letter read:

Monsieur Attorney General: I have the honor to inform you of an exceptionally serious occurrence. I speak of a spinster who is locked up in Madame Monnier’s house, half starved, and living on a putrid litter for the past twenty-five years–in a word, in her own filth.

This “Madame Monnier” was a 75-year-old widow named Madame Louise Monnier Demarconnay. To many, she was an upstanding citizen. She lived in an affluent neighborhood along with her son, Marcel. Her late husband Emile had been the head of a local arts faculty. Marcel was a law school graduate and a former administrative official with the Puget-Théniers commune.

Authorities were skeptical of the letter’s allegations. Still, they recalled the public heartbreak of 25 years prior, when the Monniers’ daughter Blanche vanished without a trace. Blanche was known as a “joyous and playful” woman with a “wealth of beautiful hair and big, brilliant eyes.” Perhaps the letter was a twisted hoax—then again, what if it was true? Police decided to investigate.

The door was locked when authorities arrived at 21 rue de la Visitation. When no one answered, they forced it open—and were hit with a wretched smell. They followed the stench upstairs to the attic. When they entered the room, they found a casement window covered by heavy curtains and coated in a layer of dust. Police could not open the shutters until they removed the hinges.

And when daylight finally spilled into the musty chamber, a shocking sight came into focus.

In the back corner, covered by a filthy blanket, was a skeletal, but still living Blanche Monnier. She was completely naked and lying on a rotten straw mattress, which had been soaked through by urine, feces. Fragments of meat, vegetables, fish, and bread formed a foul crust around her body. Now 49 years old, Blanche had withered down to 55 pounds.

Through bouts of gagging, police wrapped Blanche in a blanket and rushed her to Hôtel-Dieu Hospital in Paris. Madame Louise, meanwhile, was discovered sitting calmly in the living room of her home, wearing a dressing gown decorated with black and white squares. Son Marcel was found in an adjacent room. Police sat down the pair and began their questioning.

And it was then that the disturbing tale of Blanche Monnier came to light. When she was approximately 25 years old, Blanche had fallen for an older man—an attorney with few prospects and little wealth to his name. Rumors that the relationship produced an illegitimate child were abundant, and Madame Louise forbade Blanche from seeing the man. Blanche refused, at which point her mother begged her daughter to end to the affair. Blanche once more refused. Realizing that she would never persuade Blanche away from the penniless lawyer, Madame Louise hatched a plan with her son to force the change she desired.

One evening, Madame Louise lured Blanche into an upstairs room and locked her inside. She told her daughter that the door would remain locked until Blanche agreed to break off the courtship. Madame Louise felt she had found the perfect solution to her problem. Certainly, Blanche would relent.

But Blanche did not relent.

And so, Madame Louise kept her daughter prisoner, feeding her scraps and ignoring the growing number of rats that congregated in the attic to feed on Blanche’s vomited food. As Blanche withered away, her lawyer lover died in 1885.

Madame Louise was arrested on the evening of the Blanche’s rescue. She was soon transferred to the prison infirmary when it was discovered that she suffered from heart problems. Fifteen days later, she was dead.

Accused of being an accomplice, Marcel stood trial alone; the proceedings began in October 1901. He claimed that his sister Blanche was insane, and that she had not been restricted at all, but rather chose to stay in the room as an act of defiance. Court testimony contradicted Marcel’s defense. Several witnesses claimed that a woman, presumably Blanche, could be heard screaming from an upstairs room in the house. One witness professed to hearing specific words being shouted:

“What have I done to be locked up? I don’t deserve this horrible torture. God must not exist then, to let his creatures suffer in this way? And no one to come to my rescue!”

Four days after the trial began, Marcel was found guilty and sentenced to 15 months in prison. Outside in the Palace Square, a waiting crowd voiced their approval of the verdict. But in mid-November, Marcel appealed the decision—and won. The court found that he had never acted violently towards his sister and acquitted him. To the public’s shock, he walked out a free man.

Blanche Monnier’s initial prognosis was grim; death seemed imminent. In addition to the harm done by her starvation, Blanche could not tolerate light, as her eyes had sustained damage from the perpetual dimness of her attic prison.

Miraculously, Blanche’s physical state did improve, assisted no doubt by the availability of clean air and proper food. Yet she never regained her sanity. Twelve years after being rescued from the worst conditions imaginable, Blanche Monnier died in a psychiatric hospital in 1913.

The author of the anonymous letter has never been discovered.
