(1890*-1964) English-Australian mystery writer, who roamed in his youth the sub-continent working as a boundary-rider, cattle-drover, rabbit-trapper and station-manager. Upfield's famous hero is the Inspector Napoleon Bonaparte (or 'Bony', as he is known in the books familiarly), the son of an unknown white man and an aborigine mother. Bony is a gentleman and genius of criminal science, who has an M.A. degree from Brisbane University. In his work Bony frequently faces race prejudices but wins them with his wit and smile.
The inimitable Detective-Inspector Napoleon Bonaparte is on an island amidst treacherous waters. Venom House, the Answerth family mansion that is haunted by ghosts of aborigines, is playing host to a couple of murders that Bony must delve into.
