Percy Toplis
Francis Percy Toplis (22 August 1896 – 6 June 1920) was a British criminal and imposter active during and after the First World War. Before the war he was imprisoned for attempted rape. During the war he served as a private in the Royal Army Medical Corps, but regularly posed as an officer while on leave, wearing a monocle. After the war he became notorious following the murder of a taxi driver and the wounding of a police officer who attempted to apprehend him. The manhunt was major news at the time.
