Query: what a mess

I eagerly awaited new characters as I grew tired of Dr. Scarpetta in the last book. That book was all about feeling sorry for oneself and reviewing everything that happened in earlier books. What a waste.However, Isle of Dogs is so boring. I read about a third, then decided to check Amazon to see if I was missing something. Seems about everyone agrees with me. Some of the humor is interesting. Especially since it is new for Cornwell. The plot is so silly. Cornwell's first four books were great. After that, beats me what happened.
