Sam Greenlee, American author and poet (b. 1930)
Samuel Eldred Greenlee, Jr. (July 13, 1930 – May 19, 2014) was an American writer. He is best known for his novel The Spook Who Sat by the Door, first published in London by Allison & Busby in March 1969 (having been rejected by dozens of mainstream publishers), and went on to be chosen as The Sunday Times Book of the Year. The novel was subsequently made into the 1973 movie of the same name, directed by Ivan Dixon and co-produced and written by Greenlee, that is now considered a "cult classic".
