Although I have noted that many reviews were disappointed in this offering by Patterson and DeJonge, I found the story engaging and well done. However, I listened to it on an audiobook,and that may reflect my overall satisfaction. Unlike most CD books, there was a variety of actors, a different one for each of the many characters. This provided a very interesting listen since I felt the readers characterized their roles with considerable skill. Since the story was told from the variety of viewpoints, one chapter devoted to one voice, it was possible to keep the reader/listener unaware of the villain's identity. The twist at the end took me completely by surprise, but was a satisfactory turn of events for this story. The tricky device of multiple points of view allowed the authors to keep the reader/listener 'in the dark' until the unusual climax arrived. This book doesn't measure up to an Alex Cross novel, but it has merit and is a good crime drama.
