Being a London prostitute in the 1930s was a grimly hazardous business. The body of one of them, Jeanette Cotton, 44, was discovered in her room in Lexington Street, Soho, on Thursday, April 16th, 1936. She had been strangled with her own silk scarf. Her murder was linked with two other unsolved prostitute murders at the same time in Soho – those of Josephine Martin, murdered in November, 1935, and of Constance Hind in May, 1936, who were also both strangled in their rooms.
