The case of Dr. Crippen has passed into folklore as one of the most infamous in criminal history. The year: 1910. The details: a hideously mutilated body in the cola cellar, a dockside arrest in Canada – by the means of the new wireless telegraph – of Crippen and his mistress, disguised as a boy, the trial with legal luminaries and society notables. There was enough sensation to place Crippen in the top ranks of master criminals. Yet Crippen was a quiet, meek little man, a hen-pecked husband who was always gentle with his shrewish wife, a business failure passionately in love with his competent young secretary, a bungler whose one venture into murder went wrong at every step of the way. This study examines the character of the man many believed incapable of murder and reveals the story of a mismatched marriage and a love affair that – out of its context – would have been an inspiration. Illustrated with black and white photographs. Appendix reproduces Crippen’s letters to Ethel LeNeve, written from Pentonville Prison.
