This book seems to be popular with readers, like myself, who live in Cambridge. It does paint a realistic picture of Cambridge: there's a real university there with departments in which academics work, with all their rivalries and misbehaviour, not just the ancient colleges that the tourists visit. The departmental politics and machinations are convincingly displayed, much the same all over the world, of course. The body count is quite high, and is increased towards the end, and looked for a time as if even more characters might be wiped out. The real message of this novel was, I thought, don't keep things from your new wife. It's fairly clear who the murderer is, so four stars, but then it is the hardest thing to keep that hidden right up to the end. It's a good read.
