Daniel Mainwaring

Daniel Mainwaring (aka Geoffrey Homes) (July 22, 1902 – January 31, 1977) was an American novelist and screenwriter. A native of Oakland, California, he began his professional career as a journalist for the San Francisco Chronicle and enjoyed a successful career as a mystery novelist (under the name Geoffrey Homes). He worked as a film publicist and eventually abandoned fiction for a successful career as a screenwriter. His first novel (and the only one he ever published under his own name), One Against the Earth, was a proletarian novel about a young man born on a California ranch who becomes a drifter and is eventually unjustly accused of attacking a child, was published in 1932. He made his real mark, however, with a string of hard-boiled mystery novels (mostly with small-town California settings), the first of which was The Man Who Murdered Himself (1936).
