This murder mystery melodrama has handsome ex-RAF officer John Harding (Terence Morgan) come to stay at the flat of his breezy friend, Dick Stevens (Michael Medwin).
John is trapped on the balcony when the french windows slam closed and climbs into the supposedly empty flat next door. There he bumps into a beautiful girl (Joyce Howard), dressed in black and, after mumbling his apologies, hurriedly makes an exit.
Dick scoffs at John’s story, but John determines to learn more about the mysterious lady.
In due course, he learns that George Bentley (Andrew Osborn), the one-time occupant of the flat, murdered his wife and the mysterious lady is the victim’s twin sister.
John helps the ” spirit ” to do a little cleaning up and sees Bentley come to a fitting end.
John and “the lady in black” are hand in hand when the curtain drops.
Terence Morgan is a trifle camera conscious, but otherwise, he contributes a sound and engaging performance as John. The film has little reason and less logic, but its cast and camera are used to advantage and between them, they create a good atmosphere of mystery.
