Keepers of the gate

Sinopse

"How are the 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 his Israeli detective colleague, Danielle Barnea, soon discover that the answer lies as much in the past as in the present, with the clues leading from a Nazi labor camp to the forefront of modern biotechnological research, while leaving a trail of deception and death behind."--Jacket.
