Pontifex, Son and Thorndyke

Dr. Richard Austin Freeman (11 April 1862 – 28 September 1943) was a British writer of detective stories, mostly featuring the medico-legal forensic investigator Dr. Thorndyke. He invented the inverted detective story (a crime fiction in which the commission of the crime is described at the beginning, usually including the identity of the perpetrator, with the story then describing the detective's attempt to solve the mystery). This invention has been described as Freeman's most notable contribution to detective fiction.
