The Melody of Death

Gilbert Standerton learns that he has been disinherited by his cantankerous uncle, and is forced to find a way to provide for his newly wedded high-society wife. After quitting his appointment at the Foreign Office, he develops a new interest in the stock market, and takes an avid interest in the antics of a gang of safe-cracking burglars. His wife becomes concerned as he frequently begins staying out late at night, and shows an unusual interest in a particular musical melody despite having lost interest in all of his other music interests.
