Easy to read but not particularly well written - with far too much medical explanations that don't make a difference (I don't care how they do something, just that it's doable). Disappointing ending as there was a lot of build up then suddenly it climaxed so fast it only took a page or two with no decent lead in to. Also, as a murder investigation book - I was told who it was about half way through, they just couldn't find him and didn't know how he managed to foil the murdered. An ok read if you want something relatively brain-deadening and easy.
