A mystery man was known to be hanging around London railway stations offering sweets to little girls to “accompany” him. Was he the killer of seven-year-old Margaret Nally?

The little girl’s body was found around midnight on Sunday, April 4th, 1915, by a railway inspector in the ladies’ waiting-room at Aldersgate station. She had been suffocated with her own handkerchief, which was forced down her throat, and the rape inflicted on her had been so severe that it ripped open her vagina, causing terrible injuries.

Margaret was last seen alive playing near her home in Paddington, which is some distance from Aldersgate. The mystery man was described as of medium height, fresh complexion, clean-shaven and with dark hair.
