Service Of All The Dead is the fourth book in the Inspector Morse cycle. As usual Oxford is beautifully described, and is virtually an additional character in the novel. There's a great cast of characters, some more eccentric than others, and a plethora of bodies.
The only downside was that I didn't have any belief in the novel at all. The novel is told from several different angles, and the non-Morse angles are not convincing - it's also fairly obvious when the novel is told in this way who the murderer is (although it is slighly more complicated than that - I won't say more in case you haven't read the novel yet).
The first murder, although ingenious, was just plain stupid - Morse gives what are supposed to be convincing reasons for why the murder happened in this way, but it doesn't hold water, and I found myself getting quite annoyed with the novel. It's a not too complicated intro to the Morse cycle, he's rather more genial here than he is in some of the other novels, but I don't think it's a particularly good example of the series.
