(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.
A woman is slain and her young daughter has vanished deep in the Australian outback. It is up to Detective-Inspector Napoleon Bonaparte to discover whether Ole Fren Yorkey, a half-crazed wanderer, is a killer and solve this dangerous riddle.
