At first it was thought that the mutilated woman found in a railway tunnel had committed suicide. The discovery was made on the evening of SEPTEMBER 24th, 1905, in a tunnel near Merstham on the London to Brighton line, but closer inspection of the woman’s body revealed that she had been gagged. Part of a scarf was found in her mouth, and scuff marks on the tunnel wall indicated that she had been thrown from a train.

The top of her skull had been cut clean away at the hair-line, apparently by a carriage-wheel. Part of her veil was embedded in her brain, her nose was broken, probably through striking the tunnel-wall, both her thighs were fractured and she had been disembowelled.

“I think she was gagged by someone in the carriage with her,” said the doctor who examined the body. “She was not suffocated by the gag. The door was thrown open in the tunnel, and she was thrown out still alive by a person of some strength.”

A dairy farmer from Kingston Hill, Surrey, identified the victim as his 22-year-old sister, Mary Sophia Money, a book-keeper who worked for a dairy at Clapham Junction. And that was as far as the investigation got, the murder remaining unsolved.
