A rather hesitant Jimmy is sent to break into Markham's safe but he finds someone else has beaten him too him and a little later Markham is found dead! Now Carol, Jimmy and Markham's associates and staff must discover who killed him and what happened to the blackmailer's dossier...
An interesting little whodunnit with a number of possible suspects. Was it Emma (Ingebord Wells) the maid, who has a secret reason for being in the house? Or the American Carter (John Arnatt) who is keen to take charge? Or maybe the butler Bassett (Denis Shaw) who likes to spy through keyholes?
The film is low budget, taking place mostly in Markham's house but makes the most of the budget and keeps you guessing and has a number of good twists. The only really black mark against it is the weirdly jaunty soundtrack.
