The Scarlet Claw takes Sherlock Holmes and Dr. Watson to the exotic locales of Canada (none of which we ever see) where they’re attending the Royal Canadian Occult Society Conference in Quebec City. Before they've even had a chance to attend any breakout sessions or pass out their swag, they’re tasked with investigating a murder. The nearby village of La Mort Rouge is beset with mysterious killings, which locals believe is the work of a monster who lurks in the surrounding marshes. But Holmes suspects the killer walks among them. (Bill Cartledge fans, you’ll want to keep your eyes peeled for his uncredited-yet-brilliant portrayal of Hotel Bellhop.)
