(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.
Merino is an isolated town in New South Wales. Posing as a laborer, Bony goes there to investigate the murder of a vagrant and soon discovers a murderous tangle of motives and suspects. There are some very engaging characters and some excellent trakcing scenes leading to a suspenseful finish.
