Based on Raymond Chandler's THE BIG SLEEP, this film at first appears to be a parody of that classic but then settles into being merely a copy. Reynolds plays it for laughs and manages to give the feeble comedy lines the right delivery which helps a bit. He's a Brooklyn private eye who
sleeps on a pool table above a billiard parlor. He gets a phone call asking him to visit the estate of the wealthy Weyand, a diamond merchant who keeps his house cooled to 40 degrees while he sips iced tea. (In THE BIG SLEEP, Bogart had to perspire as he met his client in a hothouse.) Weyand says
that some diamonds have been stolen, and Reynolds can pick up 10 grand if he finds them....
