This book was a very pleasant surprise, far too often today thrillers are formulaic and predictable, the "bad guy" standing out by a country mile. Not the case in the clever well written interesting tale. The plot and the characters are extremely well written, very real and often very flawed, the true triumph of the book being Gil Eckhart, such a multi dimensional interesting lead character, but with a great supporting cast.
The back plot of Caravaggio provides an educational and illuminating setting both in the world of the art trade and also with the use of timeslip 1608 Europe. I loved the idea of a long lost descendant suddenly appearing and throwing the art world into turmoil with the revelation that not one but two long lost master pieces could be about to resurface. The resulting appearance of an old Killer, many years silent is both disturbing and chilling, with some very cleverly derived murders.
The book sped by and entertained me immensely.I will be without doubt picking up the other books by this author, finding a good thriller writer is hard, finding a great one is nigh on impossible. (thanks Milo for this tip)
