THE SINISTER PAST

Between late 1884 and Christmas Eve 1885, an unidentified killer murdered eight women in Austin, Texas — most of them domestic servants, attacked at night with an axe, several with a sharp implement driven into one ear. No one was ever convicted.

This episode covers the Servant Girl Annihilator case month by month, the racially charged wrongful arrests that followed, and the theory — unproven, but persistent — that connects Austin's forgotten killer to a much more famous one who began killing in London less than three years later.

In 430 BC, Athens packed tens of thousands of war refugees inside its own city walls as a military strategy — and then a disease no ancient physician could name tore through the crowded city, killing up to a third of the population, including its greatest statesman.

This episode covers the outbreak through the eyewitness account of the historian Thucydides, who caught the disease himself and survived: the symptoms, society's collapse, and a modern mystery — scientists still don't agree on what disease it actually was.

During Chicago's 1893 World's Fair, a charming doctor named H.H. Holmes rented rooms in a building he'd secretly designed to make people disappear — windowless chambers, hidden gas lines, chutes to a basement fitted with acid vats and a kiln.

This episode traces Holmes from a small-town con man to the insurance fraud that finally caught him, the murder of his own associate and three children, and the disputed real body count behind a story that's been exaggerated for over a century.

On December 4, 1872, the crew of the Dei Gratia found the merchant ship Mary Celeste adrift in the Atlantic — seaworthy, food and cargo intact, and completely deserted. Ten people, including a captain, his wife, and their two-year-old daughter, had vanished without a trace.

This episode covers the ship's final voyage, the leading theory involving nine oddly empty alcohol barrels, the conspiracy-driven Gibraltar hearing that accused an innocent crew of murder, and the fiction that turned a real mystery into a legend.

On the morning of June 10, 1912, a neighbor found the Moore family's Villisca, Iowa farmhouse locked and silent. Inside: eight bodies — six family members and two young houseguests — all killed in their beds with an axe taken from the family's own woodshed.

Every mirror in the house had been covered. Every door was locked from the inside. Two men stood trial and both walked free. Decades later, researchers linked the murders to a string of near-identical axe killings across the American Midwest — and the case remains, over a century later, one of America's oldest unsolved mass murders.

At 1:23 AM on April 26, 1986, a routine safety test inside Reactor Four of the Chernobyl Nuclear Power Plant went catastrophically wrong — and thirty-six hours later, a purpose-built Soviet city of fifty thousand people was emptied in under four hours, never to be permanently lived in again.

This episode covers the disaster hour by hour: the flawed test, the firefighters who climbed onto an exposed radioactive core with no protective gear, the Soviet cover-up that only broke because of radiation alarms in Sweden, the liquidators nicknamed 'bio-robots', and the ghost city — Ferris wheel and all — still standing exactly as it was left.

In August of 1977, a police constable in a quiet North London council house watched an armchair slide across the carpet with no one near it — and put her name to a signed statement saying so.

Over the next thirteen months, the Hodgson family's ordinary home became one of the most exhaustively documented poltergeist cases in British history: thirty hours of tape, a voice that wasn't a child's, a photograph that still divides believers and skeptics, and an investigator who never stopped looking for proof his own grief could be answered. Some of it was later proven fake. Most of it never was.

In the small hours of a September morning in 1889, a constable's lantern found a woman's torso hidden under a railway arch in Whitechapel — headless, legless, and eerily similar to something London had already seen three times before.

This is the story of the Thames Torso Murders: four dismembered women, scattered across the river and the streets of London between 1873 and 1889, by a killer methodical enough that Scotland Yard's own detectives ruled out Jack the Ripper. Only one victim was ever identified. No one was ever charged. And more than a century later, historians think they may finally know who did it.

North Sea, November 1983. A catastrophic failure in a diving bell's pressure chamber causes an explosive decompression from 9 atmospheres to 1 in a fraction of a second. Four divers and one tender die instantly. The physics of what happened to their bodies is difficult to describe and impossible to forget.

In this episode, we trace the mechanical failure behind the Byford Dolphin accident, the missing safety interlock that made it possible, and the 26-year fight the victims' families waged just to be acknowledged — a case still taught in safety engineering courses worldwide.

London, 1837-1904. For nearly seventy years, witnesses across England report attacks by a tall, thin figure who breathes blue fire, has clawed hands, and can leap over walls and buildings in a single bound. Police investigations find nothing. Military patrols find nothing. The sightings simply stop — and no explanation is ever offered.

In this episode, we trace the documented paper trail behind Spring-Heeled Jack, from Mary Stevens's 1837 attack and the Jane Alsop and Lucy Scales cases that made him a national sensation, through the Aldershot and Lincolnshire military incidents of 1877, to the final 1904 sighting that closed the case without ever solving it.
