Keeper of the gate

the long version

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.
