The Triumph of Sherlock Holmes

Directed by Leslie S. Hiscott

With Arthur Wontner, Lyn Harding, Leslie Perrins, Ian Fleming and Charles Mortimer

Holmes, retired to Sussex, is drawn into a last case when his arch enemy Moriarty arranges with an American gang to kill one John Douglas, a country gentleman with a mysterious past. Holmes' methods baffle Watson and Lestrade, but his results astonish them. In a long flashback, the victim's wife tells the story of the sinister Vermissa Valley.
