Query: A Disaster

I've read all the Martha Grimes books and have looked forward with eager anticipation to each new book. How disappointing this one was. I think she has gone mad. Richard Jury looks like an idiot, Plant and his friends are brought in because it is a necessity in a Jury book. None of them has a role to play in solving the mystery and Carol-Anne is just window dressing. The dog is smarter than anyone else in the book. What in the world is going on here?? I think Martha has become obsessed with the idea of the paranormal and that does not mix well in a traditional murder mystery. I'm sorry I bought it and I don't think I am going to purchase any more of Martha's books. The plot made no sense, the people made no sense, and the ending was absurd.
