Sam Greenlee, American author and poet (died 2014)

Samuel Eldred Greenlee, Jr. was an American writer of fiction and poetry. He is best known for his novel The Spook Who Sat by the Door, first published in March 1969 in London by the recently founded small imprint Allison & Busby, having been rejected by dozens of mainstream publishers, and received much critical attention, including extracts being printed in The Observer newspaper. 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.
