I discovered Peter James when I read his previous thriller, Dead Simple, which was excellent. And he betters that with Looking Good Dead.
From a very basic, simple premise, the laptop left on a train, the poor unfortunate who finds it is catapulted into a world of mayhem and potential murder, simply by doing things which any reader could imagine themselves doing - and this is what Peter James does so well, it could happen to anyone.
Once into the story, the plot moves swiftly, but not so you can easily spot the twists, and the characters are completely believable, whether on the side of the angels or not. You'll be hard put to stop reading this once you've started, I certainly couldn't, highly recommended to lovers of thrillers/detective fiction
