I rather enjoyed this final outing for our deductive duo, as they have to get to the bottom of the mysterious murder of the rather unfortunately monikered "Stinky" (Edmund Breon) who went to school with "Dr. Watson". His rather brutal murder is inexplicable, but for the theft from his home of a rather ordinary musical box made at Dartmoor prison. Further investigation reveals the boxes were made by a felon with a very important secret to keep, one which "Mrs. Hilda Courtney" (Patrcia Morison) who likes a little perique in her cigarettes, and her henchman "Hamid" (Harry Cording) will stop at nothing to possess. Again, as with so many of these - it's actually Nigel Bruce ("Watson") who steals the show and saves the day - and together with Basil Rathbone they sign off this series on good form and in good spirits. PS: What did Dr. Samuel Johnson die of...?
