During WWII, Dr. Watson (Nigel Bruce) attends the patients at Musgrave Hall, a stately English country home being utilized for shell shocked soldiers. When a doctor (Arthur Margetson) is stabbed while taking a walk, Watson calls in his friend Sherlock Holmes (Basil Rathbone) to investigate. Based on a short story by Sir Arthur Conan Doyle, this is one of the better Sherlock Holmes adventures courtesy of Universal. While it never rises above routine, it's short (69 minutes) and to the point. As directed by Roy William Neill, who directed 11 Holmes mysteries, it moves along nicely while providing a suitable atmosphere. Mystery fans and especially Holmes fan should find it pleasing. With Hillary Brooke, Milburn Stone, Halliwell Hobbes and Norma Varden.
