I think this is one of my favourite of the rat series. The first held the opening thrill and some of the ones up until this point have been enjoyable, but nothing's really taken us back and given us some of our heroes history. it is this history that makes the man, of course; and so although it may seem a little cliched and repetitive to hear of the same rationales for crime, there's nevertheless a fresh twist on the whole shebang - truly a breath of fresh air.
