Just finished "The Riddle of the Third Mile" by Colin Dexter, the 6th book in the "Inspector Morse" series. In this story, Morse is faced with two mysteries to solve: the disappearance of a distinguished academic from his Oxford College, and the discovery of an unidentifiable torso in a local canal. The obvious assumption is to assume the body to be that of the academic, but the truth is much, much more complex.
This is one of the best "Morse" novels. Not only is it an interesting, well-told story, with an ending which took me totally by surprise, but in this book we also find out about Morse's own past history as an Oxford student, cut short due to a disastrous love affair.
Very highly recommended.
