My dad once said to me, "You give a lot of books three stars." I do.
This volume strays the furthest from Holmes canon. Several of the stories are inspired by original Sherlock Holmes stories (their version of Moriarty shows up), or cases mentioned in the stories (like The Giant Rat of Sumatra). I didn't mind this deviation because I liked the characters and the stories were interesting. I thought the ending was quite anticlimactic though.
