Three unarmed police officers gunned down in a botched jewellery heist. Two desperate Latvian anarchists barricaded in a East End house. Hundreds of bullets flying as Winston Churchill himself arrives on the scene in a top hat.

This is the true story of the Sidney Street Siege — one of the most dramatic and controversial shootouts in British history.

In this episode of A True Crime Podcast, Alexander Lawson takes you back to January 1911, when a quiet London street turned into a six-hour battlefield. Discover how a gang of revolutionary exiles sparked a manhunt that ended in fire, death, and national outrage.

A forgotten chapter of true crime that still echoes more than a century later.

A quiet London boarding house. A trusting lodger with a small fortune. And a landlord who saw dollar signs in every dose of arsenic.

In 1911, insurance superintendent Frederick Seddon convinced eccentric spinster Eliza Barrow to hand over her life savings in exchange for a modest annuity and a place to live. Months later she was dead — her body laced with poison, her money safely in his pocket, and a cheap funeral already arranged.

Join host Alexander Lawson as he unravels the cold, calculated case of one of Edwardian England’s most notorious poisoners: the flypapers, the forged will, the arrogant testimony that sealed his fate, and the Masonic plea that failed to save him from the gallows.

A quiet North London house. A mild-mannered American doctor. His wife vanishes. Police dig up the cellar… and find a torso wrapped in his pajamas, soaked in poison.

Meanwhile, Dr. Hawley Harvey Crippen is already halfway across the Atlantic with his young mistress—dressed as a boy.

This is the true story of one of the most sensational crimes of the Edwardian era: the 1910 murder of Cora Crippen, the first criminal ever caught by wireless telegraphy, and a chase that gripped the world. From the discovery of the remains at 39 Hilldrop Crescent to the dramatic arrest on the SS Montrose and the lightning-fast trial at the Old Bailey, host Alexander Lawson takes you inside the case that helped invent modern forensic true crime.

Was Crippen a cold-blooded killer… or a man executed for a crime he didn’t commit?

In 1879, Irish maid Kate Webster threw her employer down the stairs, strangled her, then carefully cut the body apart and boiled the pieces in a laundry copper. For the next two weeks she lived in the dead woman’s house, wore her clothes, sold her furniture, and introduced herself as Mrs. Thomas.

When the remains washed up in the Thames the press called it the “Barnes Mystery.” The killer fled to Ireland. The missing head stayed hidden for 131 years—until it turned up in David Attenborough’s garden.

This is one of the most grotesque true crimes of the Victorian age.

Imagine stepping off a quiet train in 1980s London… and never making it home.

Between 1982 and 1986, Irish-born John Duffy and his childhood friend David Mulcahy turned the railways of southern England into a hunting ground. Dozens of women and girls were raped. At least three were murdered. They called their attacks “hunting parties.”

In this episode of A True Crime Podcast, host Alexander Lawson uncovers the chilling story of the Railway Rapists who became the Railway Killers — the friendship that turned deadly, the pioneering police investigation, and the confession that finally brought both men to justice.

Two elderly women butchered in their beds in Dublin. A young couple stabbed to death in Roscommon. A false confession that sent an innocent man to prison. A killer who admitted everything… then took it all back.

This is the full story of Mark Nash — the man behind the horrific Grangegorman murders and the Roscommon killings. From the most savage crime scene Ireland had ever seen, to a decade of legal battles, DNA evidence that waited years to speak, and justice that finally arrived nearly 20 years later.

In 1983, a homeless Irishman named Kieran Patrick Kelly was arrested in London for a minor crime. By morning, his cellmate was dead — strangled. Then Kelly started talking.

Over hours of chilling confessions, he claimed he had spent three decades pushing people in front of trains on the London Underground, setting others on fire, and poisoning the forgotten. If true, he may be one of Britain’s most prolific serial killers… and almost no one knew his name.

Was Kieran Patrick Kelly a calculating mass murderer who hunted in the “Nobody Zone,” or a damaged fantasist whose stories grew with every telling?

Tonight, Alexander Lawson unravels the dark, contested story of the man from Rathdowney who turned the London Tube into his killing ground.

In the summer of 1976, two Englishmen made a pact: abduct, rape, and murder one woman every single week until they were caught.

Geoffrey Evans and John Shaw turned the roads of Ireland into hunting grounds. They took Elizabeth Plunkett. Then they took Mary Duffy. One body was tied to a lawnmower and dumped in the sea. The other was weighted with concrete and sunk in a lake.

They confessed. They blamed each other. And to this day, one of those murders has never produced a single conviction.

This is the story of Ireland’s first serial killers… and the deadly schedule that almost continued.

In 1828 Edinburgh, two Irish immigrants discovered a deadly shortcut to cash: kill the living, sell the corpses to anatomists, and never dig a single grave. Over ten months William Burke and William Hare smothered at least sixteen victims — the poor, the forgotten, the convenient — then delivered the still-warm bodies for profit. Host Alexander Lawson uncovers the West Port murders, the immunity deal that saved one killer, and the scandal that forced medicine to change forever. Listen now.

He had the face of an angel. Soft features. Blond hair. A gentle voice that made mothers trust him with their deepest pain.

In 1977, Alfredo Astiz posed as one of them — a brother searching for his disappeared sibling — and walked straight into the heart of the Mothers of the Plaza de Mayo. Within weeks, the vans came. The founders were taken. Two French nuns vanished with them. Most were never seen alive again.

This is the story of Argentina’s Blond Angel of Death, the ESMA torture center, and one of the most calculated betrayals of the Dirty War.
