La garra escarlata

Roy William Neil continued to direct this series, and this is one of the best. Story is not adapted by a Sir Arthur Conan Doyle tale, but instead tells an original one. Holmes & Watson are in Quebec Canada to attend a conference when they are called upon to investigate a murder of Lady Penrose, who had in fact already contacted Holmes, but was too late to save her. Locals believe it to be a supernatural creature at work, but Sherlock knows better. Atmospheric and exciting entry seems inspired by earlier "The Hound Of The Baskervilles", but is better handled here. The series was at its peak now, and in the next two entries as well.
