Three years have passed since Sherlock Holmes and his nemesis Professor Moriarty vanished into the abyss of the Reichenbach Falls. In that time, the criminals of London have been able to sleep safe in their beds. But with the murder of society card player Ronald Adair and the resurgence of the Moriarty syndicate, the capital has never been in greater need of its protector. A triumphant return from the dead. Nigel Miles-Thomas and Michael Roy Andrew resume their acting partnership which has spanned four decades. Adapted from The Empty House by Arthur Conan Doyle.
