Dressed to Kill was released in 1946 and features Basil Rathbone and Nigel Bruce. The film was the last of fourteen films starring Rathbone and Bruce. A convicted thief in Dartmoor Prison (played by an uncredited Cyril Delevanti) hides the location of stolen Bank of England printing plates inside three music boxes (each of which play a different version of 'The Swagman'. The boxes are then sold to a local auction house. Sherlock Holmes sets out to discover why a trio of murderous villains, including a dangerously attractive female, are desperate to obtain three unassuming and inexpensive little music boxes. The head of the gang belongs to a darkly, beautiful and ruthless woman, who is also a consummate actress as Holmes soon learns. She disguises herself as a charwoman and speaks Cockney, which both insults and berates both Holmes and Watson. The beautiful woman pretends not to recognize Holmes and Watson and she leaves with a music box right under their noses. Holmes must recover the last music box to crack the secret code contained in the tune before it is too late. Another fantastic tale of mystery and suspense which only the likes of the famous duo of Holmes and Watson can solve.
