Given the 2 rave reviews, I thought to experience a universe such as "substitution;! Nay These two commentators say that this is the 3rd T. Carver and does not demerit I will see. the comments on the second title "ranger" and there no comments 2 fans ?? I have long hesitated to put my review because this book put me in confusion: the phrasing is good, well-drawn characters (we manage to hate the Divisional Head Brass) BUT in "Substitution" there was the orignalité (in horror, of course), the mystery until the last line. For this one, from half we swim in the banality of a thriller. It has the gardener, but he too recalled those leaving "The Breach" in "Blood Brothers" by Michael Marschall. Too bad! I hope you give better news this author after reading "The Rover" which is still in my stack "to read".
