AMBUSH ON THE BROOKLYN BRIDGE! The Brooklyn Bridge is as good a place as any for Ezra to take a clandestine meeting with Karl Meyer, the man who could help him bust this case wide open. But mechanical monsters lie in wait, and Ezra's life is put right on the line. He knows too much now, and the only way to stay alive is to act fast. What he finds at the Clockworkers' Union might mean he's already too late!
