This is probably the funniest Inspector Morse mystery I have read so far.
What do you do if you are caught with your pants or your knickers down in an extra-marital affair?
Well, you have really two options. You can either kill your partner or you can kill your lover. This is roughly the story of this book in a nutshell. The actual murder takes place in the annexe of an Oxford Hotel but the option chosen is only revealed towards the end of the book. Although the people involved in the plot stay at the hotel under assumed names, Chief Inspector Morse works out the real name of the person at the centre of the plot and even though he explains his line of argument to Sergeant Lewis I found that argument a bit hard to follow. But the identification of that person does help him a lot towards solving this mystery.
A third option would of course have been for the person at the centre of the plot to get rid of both partner and lover and the book gives the impression that that is an option which may have been seriously entertained but whether this is indeed the case is again not revealed until the very end of this book.
Similarly to his other Inspector Morse novels I found this book a real page turner. I would assume that the purpose of these novels is not to write them in such a way that they can easily be adapted to television but rather to serve as enjoyment to the reader and I think Colin Dexter has again done an excellent job.
