Last year, NPR correspondent Eric Westervelt toured Nablus in the West Bank with me, talking about my third Palestinian crime novel THE SAMARITAN'S SECRET as we wandered through the ancient casbah. Sadly for the many of us in Jerusalem who enjoyed his dry wit, Westervelt has left the Middle East for a new posting in Berlin. But we can still listen to his radio pieces, which he prepares with an ear for colorful sound that's truly distinctive. He hasn't quit the world of crime fiction, either. This week, he features Philip Kerr's excellent series about a German detective in Berlin during the 1920s and 1930s, and an intriguing piece it is.
