Cthulhu Casebooks: Sherlock Holmes & the Sussex Sea-Devils by James Lovegrove

Author James Lovegrove brings us the final battle between Sherlock Holmes and the persona once known as James Moriarty now known as Relulog. Doctor Watson travels from London to Sherlock's residence in Sussex where he has been taken prisoner by a group of cultist who worship Relulog. They also have tales of Sea-Devils which makes Holmes take up the job of finding out who is behind it and expose them and turn them over to the local cops. The Sea-Devils it turns out are German and they take both Watson and Holmes aboard a U-boat which has Von Herling, the new home for Relulog aboard as they travel to an island where Cthulhu is sad to be sleeping. This maybe a shorter book but it packs a punch and is a great end to the trilogy. I highly recommend it to all Sherlock Holmes fans.
