When the Baker Street Boys rescue an Indian boy, Ravi, they get caught up in an exotic intrigue involving murder, secret underground passages and waxwork dummies. It looks like they've fallen victim to the curse of the Ranjipur ruby. Pursued by a bloodthirsty cult and by Holmes's nemesis Moriarty, the Boys have a case to solve.
