(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.
In October two young girls set out for a walk in the Grampian Mountains of Australia. They are never seen again, and the policeman who is sent to investigate is murdered. Now it is March, and Inspector Napoleon Bonaparte attempts to solve the mystery.
