Keeper of the gate

How are the shocking murders of elderly Holocaust survivors connected to the deaths of high school students in Israel and the West Bank? Palestinian-American detective Ben Kamal and Israeli detective Danielle Barnea soon discover that the answer to this blood-drenched puzzle lies as much in the past as in the present, with the clues leading from a Nazi labor camp to the forefront of modern biotech research, while leaving a trail of deception and death behind. At the center of the mystery lies Paul Hessler, a labor camp escapee and New York billionaire with secrets that stretch back over sixty years. Hessler is also in possession of a miraculous medical discovery that could affect the lives of thousands--including Ben and Danielle's unborn child. To protect this discovery, and to rescue the future form the hidden evils of the past, Ben and Danielle must come face-to-face with the Keepers of the Gate.
