The Eye of Osiris

John Bellingham is a world-renowned archaeologist who goes missing mysteriously after returning from a voyage to Egypt where fabulous treasures have been uncovered. Bellingham seems to have disappeared leaving clues, which lead all those hunting down blind alleys. But when the piercing perception of the brilliant Dr Thorndyke is brought to bear on the mystery, the search begins for a man tattooed with the Eye of Osiris in this strange, tantalisingly enigmatic tale.

Richard Austin Freeman (1862 - 1943) was a British writer of detective stories, mostly featuring the medico-legal forensic investigator Dr. Thorndyke. He claimed to have 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). Freeman used some of his early experiences as a colonial surgeon in his novels.
