A visit to Caerphilly and the Langslows is always amusing. This book does not disappoint. It is Halloween in Caerphilly and the town is hosting a Halloween festival. Rob and his company, Mutant Wizard are featured. Dr. Smoot is in all his glory with the Haunted House. Meg and Michael are on Goblin Patrol as someone is leaving fake body parts around. Grandfather has a group of Ravens following him. A stranger’ s body is found in the Haunted House. He was shot with through the head. While you can read this series as a stand alone it is better. Read in order.
