The Walls of Jericho — Jon Land

American Ben Kamal is a Detroit police detective whose police training makes him valuable to the new Palestinian police force on the West Bank. He's glad to help--but hooking up with the Israelis to find a serial killer was not part of the deal.
Danielle Barnea is the best that Shin Bet, Israel's FBI, has to offer, but she, too, resists the assignment.

Now Ben and Danielle are forced to leave personal differences behind as they realize that something much more complex than murder is behind the killings.
