1988: Harold Shipman Killed His 55th Patient, a Decade Before Anyone Stopped Him

Alice Prestwich was just another house call for a family doctor trusted by an entire community. Harold Shipman gave the 69-year-old widow a lethal injection of morphine at her home in Hyde, Greater Manchester, on 20 October 1988, the same quiet routine he had already used on dozens of elderly patients before her. She became his 55th confirmed victim, and not one soul suspected a thing.

Shipman kept practising, and killing, for another ten years, forging wills and helping himself to his victims’ assets along the way, before a suspicious bequest finally exposed him in 1998. An official inquiry later concluded he had killed at least 215 patients, making him the most prolific serial killer in British history.

1216: The Poison Toad Theory Behind the Death of King John of England

Legend has it that King John of England was not felled by illness but by a monk’s revenge. Staying at Swineshead Abbey in Lincolnshire that October, John allegedly threatened to starve his own kingdom with crushing bread prices; a monk is said to have milked a toad for its venom, mixed it into a cup of ale, and drunk from it himself before serving the king, to prove the drink was safe. The monk reportedly died first in the abbey infirmary, and John followed him within hours.

The king, already infamous for the Magna Carta he was forced to sign and then tried to annul, died at Newark Castle on 19 October 1216 as a rebel army closed in on his crumbling kingdom. The poisoning story only surfaces in a chronicle written decades later for John’s old enemies, the barons; most contemporary accounts agree he died of dysentery, the far less dramatic verdict most historians still accept today.

1907: A Doctor Fooled Twice: Martha Rendell and the Second Child to Die of Diphtheria

Seven year old Olive Morris died on this day in East Perth, her throat swabbed raw, just as her older sister Annie had died months before. Both times the family doctor, Cuthbert, signed the same death certificate: diphtheria. Both times he was wrong.

What the certificate did not record was hydrochloric acid, swabbed onto the children’s throats by their father’s partner, Martha Rendell, under the guise of treating illness. The pattern would not be noticed for two more years, until a third child in the household died the same way and police finally ordered the earlier graves reopened.

The exhumations in 1909 revealed what two death certificates had missed, and set in motion the case that would end with Rendell on the gallows.

1953: Caroline Grills Laughed During Her Own Trial for Poisoning

Caroline Grills was the kind of woman neighbours trusted: she brought cups of tea and homemade treats to relatives and friends, and several of them sickened and died. On this day she was convicted of the attempted murder of Eveline Lundberg with thallium, the same insidious poison police believed had already killed members of her own family.

Her manner in the dock attracted attention. When the jury returned its guilty verdict, Grills shrugged her shoulders and smiled broadly. After the judge recorded a sentence of death, she reportedly turned to police and asked, “Is that all?” She had protested her innocence throughout the trial.

The sentence was later commuted to life imprisonment. Grills died on 6 October 1960 never expressing remorse for the deaths linked to her name.
