American homeopath Hawley Harvey Crippen became one of history’s most notorious wife-murderers when his second wife, Cora, vanished after a dinner party at their home in Holloway, London, on the night of 31 January 1910. Crippen claimed she had returned to the United States and later died there, but Scotland Yard grew suspicious when his mistress, Ethel Le Neve, was seen openly wearing Cora’s jewellery. When police dug up the cellar at 39 Hilldrop Crescent, they found human remains.
Crippen and Le Neve fled aboard the SS Montrose bound for Canada. The ship’s captain, recognising the fugitives, used the newly available wireless telegraph to alert Scotland Yard. Chief Inspector Walter Dew boarded a faster ship, intercepted the Montrose, and arrested Crippen mid-Atlantic on 31 July 1910, making him the first criminal in history captured with the aid of wireless telegraphy. Crippen was returned to London, tried at the Old Bailey, convicted of murder, and hanged at Pentonville Prison on 23 November 1910.
