Dr Watson (Nigel Bruce) is working as a medic at a stately home serving as a convalescent home for army officers. However, strange things are happening including a maniac attacking people in the night. Watson calls his friend Sherlock Holmes (Basil Rathbone) to investigate. By the time he arrives there has been a murder. The head of the Musgrave family has been killed.
This is not the first murder. There are a number of suspects, including Sally Musgrave (Hillary Brooke) who must recite an ancient saying as she assumes her place in the family hierarchy. Did the butler do it? Brunton (Halliwell Hobbes) certainly is behaving strangely when he isn't drunk anyway! Sherlock has his eye on Dr Sexton (Arthur Margetson) however...
This is a highly enjoyable entry in the long running series with an intricate plot, the setting of a dark country house with plenty of secrets of course helps!
