Based on: Nothing Lasts Forever by Roderick Thorp

Year published: 1979

Thorp wrote the book as a sequel to his 1966 book The Detective, which itself had been adapted into a movie of the same name, starring Frank Sinatra, in 1968.

Nothing Lasts Forever was adapted into screenplay for Sinatra to star in — as sequel for The Detective — but after he declined, the script was rewritten as a standalone film.
