The murder of Julia Martha Thomas, dubbed the "Barnes Mystery" or the "Richmond Murder" by the press, was one of the most notorious crimes in the Victorian period of the United Kingdom. Thomas, a widow in her 50s who lived in Richmond, London, was murdered on 2 March 1879 by her maid Kate Webster, a 30-year-old Irishwoman with a history of theft. Webster disposed of the body by dismembering it, boiling the flesh off the bones, and throwing most of the remains into the River Thames.
