After a drunken evening, Bill Nagy is found dead the next morning. A coroner's jury finds he died of heart failure. Police Inspector Tony Quinn has his doubts, so while widow Rona Anderson is away, he has the body exhumed. An autopsy discovers the tip of a hypodermic needle in his arm, and death by air embolism. It's murder!
The cast list and the fact this is based on a stage play inspired confidence. Then I saw it was an E. J. Fancey production and almost didn't watch it. While it's a nice murder mystery, and Geoffrey Faithfull's camerawork are good, something is very wrong with the dialogue. Not only is it terribly hackneyed, but the performers speak their lines as if they had not had a chance to rehearse them.
