Morse investigates the reported theft of erotic paintings belonging to Sir Julius Hanbury, a local baronet who is one of those standing for election as the new Master of Courtney College, Oxford. As well as the pictures, Sir Julius himself has also disappeared. Morse finds Sir Julius's dead body, and at first it looks like murder, but the new police pathologist, Dr Grayling Russell, believes he killed himself. Then there is another death which is undoubtedly a murder - but how is it connected with the late Sir Julius Hanbury?

A body is found in the canal and the only clue to its identity points to a connection with one of the university's colleges. It happens that intense rivalry for one of the most prestigious posts in the university has led to murder. But which one of the highly respected contenders is the calculating killer?

Playboy architect Michael Gifford is found strangled in his car, and the only clues are a car-park ticket and his diary. Morse and Lewis uncover a love triangle involving the murdered man, and the list of suspects grows. Meanwhile, Morse considers asking Grayling Russell for a date.
