The Return of Sherlock Holmes [Full Audiobook] by Sir Arthur Conan Doyle
The Solitary House
London, Charles Maddox had been an up-and-coming officer for the Metropolitan police until a charge of insubordination abruptly ended his career. Now he works alone, struggling to eke out a living by tracking down criminals. Charles has been approached by Edward Tulkinghorn, the shadowy and feared attorney, who offers him a handsome price to do some sleuthing for a client. Powerful financier Sir Julius Cremorne has been receiving threatening letters, and Tulkinghorn wants Charles to—discreetly—find and stop whoever is responsible.
