It's hard to see the end of Morse after all these years. He seems eternal, but his habits catch up with him. The TV portrayals have been so brilliant that I can't get Thaw out of my mind, but Dexter obviously moved the character closer to Thaw, as well. There are some loose ends and inevitable at-loose-ends feelings in this book. I compare it to the deaths of other great detectives, like Poirot, who instead of leaving with a great bang, simply fade away, with notes discovered later that help explain quite what happened.
