The Crumbles Murders may refer to one of two crimes that took place on "The Crumbles", a shingle beach between Eastbourne and Pevensey Bay — the 1920 murder of Irene Munro by Field and Gray, and the 1924 murder of Emily Kaye, a pregnant woman, by Patrick Mahon.
Irene Munro, a young London typist on holiday, was murdered by Jack Alfred Field and William Thomas Gray on 19 August 1920. Her body was buried in the shingle of the beach. Field and Gray were tried and convicted at Lewes assizes in December 1920. Both men were executed at Wandsworth Prison on 4 February, 1921.
The forensic pathologist on the case was Sir Bernard Spilsbury. On 2 May, 1924, the dismembered remains of Emily Kaye and her unborn foetus were found mostly in a beach house at The Crumbles, which she had shared with her married lover Patrick Mahon. Mahon, born in 1889 in Helena Street Edge Hill, Liverpool worked as a salesman and had met Miss Kaye during a visit to the company she worked for. Four large sections, 37 smaller fragments and various internal organs were found: Spilsbury was able to reconstruct the body, but could not unambiguously determine the cause of death.
Dubbed 'the Man of Prey' by the press, Mahon was tried in Sussex before Mr. Justice Avory, (whose contempt for the prisoner shone through in his summing up) convicted and hanged for the crime in Wandsworth Prison, London in early September 1924, with differing sources giving the 2nd, 3rd and the 9th as the exact date. Anecdotal accounts suggest that Mahon offered resistance on the scaffold, apparently attempting to jump clear of the trap when the lever was pulled.
The Thames Television TV series The Killers episode The Crumbles Murder was broadcast in August 1976. It is a dramatised telling of the Emily Kaye case.
In 1984 the Australian band Severed Heads used narration from a description of the Emily Kaye murder in a radio programme by the crime writer Edgar Lustgarten as backing for their song "Dead Eyes Opened".
