This book has a very Gothic horror story, ghost story feel. I picked it up because I thought the concept of a person being possessed by the ghost of Sherlock Holmes sounded kind of funny. This is the second book in a series about a group of ghost hunters trying to get their ghost hunting documentary on television. I don't think those ghost hunter shows are very scary, anything that happens is probably clever editing after the fact. The beginning of the book was spooky enough to grab my attention. I've never read anything else by this author but I thought this book was really interesting. This is a fast paced, well-written, short read. I thoroughly enjoyed the adventure. 4 stars.
