Detective Inspector Jonathan "Jack" Whicher was an English police detective. He was one of the original eight members of London's newly formed Detective Branch, which was established at Scotland Yard in 1842. During his career, Whicher earned a reputation among the finest in Europe.

Constance Emily Kent (1844–1944) was an English woman who confessed to the murder of her half-brother, Francis Saville Kent, in 1860, when she was aged 16 and he aged three. The case led to high-level pronouncements that there was no longer any ancient priest-penitent privilege in England and Wales. Kent's death sentence was commuted to life imprisonment, and she was released after serving twenty years. In later life, she changed her name to Ruth Emilie Kaye, became a nurse and for twenty years was matron of a nurses' home in East Maitland, New South Wales. She lived to the age of 100.
