Maurice R. Coons (July 18, 1902 – October 10, 1930), known by the pen name Armitage Trail, was an American pulp fiction author, known best for his 1929 novel Scarface. This novel was based on the life of gangster Al Capone, and was adapted as the 1932 movie Scarface directed by Howard Hawks and produced by Howard Hughes. The movie of 1932 was later modernized and remade as 1983's movie Scarface. His only other significant work is the detective novel The Thirteenth Guest, though Coons is speculated to have used a variety of pseudonyms.
