Dressed to Kill (also known as Prelude to Murder or Sherlock Holmes and the Secret Code in the UK) is a 1946 film starring Basil Rathbone, Nigel Bruce, and Patricia Morison. It tells the story of three cheap musical boxes, manufactured in Dartmoor Prison, that are sold at a local auction house. However, a criminal gang is determined to steal and recover all three. Each music box plays a slightly different version of “The Swagman”. Sherlock Holmes tries to recover the music boxes and crack the secret code contained in the tune before the gang gets what they want. This is the last of fourteen films starring Basil Rathbone as Sherlock Holmes and Nigel Bruce as Doctor Watson.
