I had expected more from the book. The starting point for the story is promising, but the implementation poor. There are two narrative strands: firstly, the investigative work of the police, on the other hand the murders - which it is very irritating, at least initially, that the author constantly changed the perspective (as a part of first-person narrative, the other is not). So you know the murderer, there remains the question of the principal. Both narratives move without detours toward each other, so that surprises largely inevitable tension also. With details that the author has not so - where members of the military special forces have the expertise to dupe the forensics, will not reveal. In some places it is implausible when a victim only beaten and then his suicide is simulated. After two, at least three pages each, a new chapter begins, even if it continues with the same scene. As this begins at the middle of the next page after a big headline that brief chapter only the mind have probably about 100 to push up the number of pages. Overall it is a rather weak point, my first and probably last Patterson.
