Roderick Mayne Thorp, Jr. (September 1, 1936 – April 28, 1999) was an American novelist specializing mainly in police procedural/ crime novels.
His 1966 novel The Detective was made into a 1968 film of the same name, starring Frank Sinatra as Detective Joe Leland. He is however better known for its sequel, the bestselling novel Nothing Lasts Forever, which is the basis for the film Die Hard, starring Bruce Willis.
The Los Angeles Times called Nothing Lasts Forever, "A ferocious, bloody, raging book so single-mindedly brilliant in concept and execution it should be read at a single sitting."
Two other Thorp novels, Rainbow Drive and Devlin, were adapted into TV movies.
Thorp died of a heart attack in Oxnard, California.
