Husband and Wife Executed Together: The Tragic Case of Frederick and Marie Manning
Marie Manning was born Maria de Roux in Switzerland in 1825, to Swiss-French parents. She moved to London in search of a better life and found work as a maid to Lady Blantyre, the daughter of the Duchess of Sutherland. In the grand households of the British aristocracy, Marie developed a taste for luxury. She admired the fine clothes, the elegant furniture, the silver and the crystal. She came to dread the thought of poverty – a fear that would ultimately lead her to murder.
This is the story of Frederick and Marie Manning, the first husband and wife to be executed together in England in nearly half a century, and one of the most notorious double executions in British criminal history.
1. The Meeting of Two Ambitious Souls
Marie met Frederick Manning in London. He was a railway guard – a respectable job, but not one that could provide the luxurious life Marie craved. Frederick was a man of considerable charm but also of questionable character. He had a criminal record and a taste for easy money.
Despite these warning signs, they married. The couple moved to a small cottage in the village of Taplow, Buckinghamshire, just west of London. The house was modest, but they entertained grand dreams. They lived beyond their means, accumulating debts, and looking for a way to escape their financial troubles.
2. The Victim: Patrick O’Connor
Patrick O’Connor was a wealthy Irishman who worked as a customs officer in London. He had saved a considerable sum of money – estimates vary, but he was known to carry large amounts of cash. He was also a friend of the Mannings.
Marie saw in O’Connor an opportunity. She began to cultivate his attention, flirting with him and leading him to believe that she was interested in a romantic relationship. O’Connor, a bachelor in his 40s, was flattered and attracted. He did not realize that Marie’s interest was not in him, but in his money.
3. The Murder: November 1848
On the evening of November 22, 1848, Frederick and Marie Manning invited Patrick O’Connor to dinner at their cottage in Taplow. O’Connor arrived unsuspecting, carrying a large sum of money – likely his savings, which he had withdrawn from the bank in anticipation of a property purchase.
The three dined together. After the meal, O’Connor was led into the kitchen, where Frederick attacked him from behind, striking him with a heavy object. Marie held the victim’s legs as he struggled. They then dragged his body into the garden and buried him beneath the flagstones of the patio.
The Mannings took O’Connor’s money – a substantial sum, but less than they had hoped. Their crime had not made them rich, only murderers.
4. The Investigation: Suspicion and Discovery
The disappearance of Patrick O’Connor did not go unnoticed. He was a well-known figure in London’s customs house, and his absence after November 22 raised alarms. When investigators began asking questions, the Mannings gave conflicting stories.
Suspicion quickly fell on the couple. Police searched their cottage and found evidence of recent digging in the garden. Beneath the flagstones, they discovered O’Connor’s body. The jig was up.
Frederick and Marie Manning were arrested and charged with murder.
5. The Trial: A Sensation in Victorian England
The trial of the Mannings took place at the Old Bailey in London in April 1849. It was a sensation. The newspapers covered every detail, and the public was fascinated by the story of the glamorous maid who had married a railway guard and then turned to murder.
The prosecution presented a strong case. Witnesses testified that the Mannings had been in financial distress. Physical evidence linked them to the murder scene. The couple’s conflicting statements to investigators were introduced as evidence of guilt.
The defense argued that Marie had been dominated by her husband – that she had acted under his influence and coercion. But the jury was not persuaded. Both Frederick and Marie Manning were found guilty of murder and sentenced to death.
6. The Execution: November 13, 1849
The execution was scheduled for November 13, 1849, outside Horsemonger Lane Gaol in London. It was a public hanging – the last era of public executions in England – and thousands of spectators gathered to witness the event.
In the crowd that day was the famous author Charles Dickens. Dickens had come to observe the execution, not out of morbid curiosity, but out of a sense of social duty. He was opposed to capital punishment and believed that public executions were brutalizing to the public.
The Mannings were led to the gallows. Frederick was hanged first. Then it was Marie’s turn. The noose was placed around her neck. She was dressed in black silk – a final gesture of the vanity that had driven her to murder.
The trapdoor opened. Marie fell. She died in seconds.
7. Charles Dickens’s Reaction: A Letter to The Times
The execution of the Mannings affected Charles Dickens deeply. The day after the hanging, he wrote a letter to The Times newspaper, expressing his horror not at the crime, but at the crowd’s reaction to the execution.
Dickens described the “immense crowd” of spectators – tens of thousands of people, including “wives, husbands, fathers, mothers, lovers” who had gathered to watch two human beings die. He wrote of the “brutality, the levity, the ribaldry, the swearing” of the crowd, and their “terrible satisfaction” in the spectacle.
He argued that public executions did not deter crime – they brutalized the public. They taught ordinary people that death could be entertainment. They lowered the moral tone of the nation.
Dickens’s letter was widely read and discussed. It became a significant text in the growing movement to abolish public executions in England.
8. The Aftermath: Burial in Unmarked Graves
Like many executed criminals of the era, Frederick and Marie Manning were buried in unmarked graves within the prison grounds. Their bodies were not returned to their families. There were no headstones, no monuments, no public memorials.
For decades, the exact location of their remains was unknown. Eventually, the prison grounds were redeveloped, and any traces of their graves were lost.
9. The Legacy: A Case That Shocked the Nation
The Manning case shocked Victorian England not only because of the crime but because a woman had been executed for murder. Executions of women were rare in 19th-century Britain, and the image of Marie Manning – the former maid who had dreamed of luxury and ended on the gallows – captured the public imagination.
The case also became a rallying point for opponents of capital punishment. Charles Dickens’s letter to The Times is still cited today as a powerful argument against the death penalty.
10. Conclusion: A Crime of Greed, A Death of Shame
Frederick and Marie Manning killed a man for money. They planned the murder carefully, committed it coldly, and tried to cover their tracks. They were caught, tried, and convicted. They died on the same gallows, on the same morning, by the same rope.
But their story is not just a crime story. It is a story about the corrupting power of greed, the danger of living beyond one’s means, and the terrible consequences of putting luxury above humanity.
Marie Manning had once feared poverty. In the end, she died for that fear – not in poverty, but in shame.
