(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 the little town of Mitford, four babies have disappeared, and Detective-Inspector Napoleon Bonaparte must find them. When the fifth baby disappears, its mother is found dead beside the empty crib, but for once, Murder Must Wait.
