I too tore through this in one sitting. I was immersed in the back and forth that he was able to keep up with family and police work. I am just still wondering, how many mysteries are still left hanging there at the end. I read series novels to be able to keep up with the characters lives and careers, not to have to re-read them to figure out a clue I might have missed. Otherwise, this eagerly anticipated next installment to the Alex Cross saga was much appreicated by this reader!
