Like another reviewer I got this as part of a set and couldn't put it down.
Unlike many 'thriller' writers, you can't see quite where he is going with the story and you get the sense that his charcaters are just as suprised by plot developments as you are, a sign of a really good writer that he allows his charcters freedom.
Was very suprised to find out that he was British as would have said it wa by an American writer it was so authentic.
Atmospheric, claustrophobic with an uneasy, unsettling feel to the story and a flawed hero but not int he traditional sense, I now have all his books though this one is one of the best of the four.
Highly recommended if you like thrillers that won't let you go!
