An eyewitness to a murder calls the Pittsburgh police from one of the city's 446 bridges, then disappears. To solve the case, the police must find the bridge. But where to start? Detective Branko Radic and Officer Kathleen Mulroy seek help from a nun, a professor, a mechanic, and a tattoo artist. They learn of a family feud, a business in trouble, some sketchy Harry Potter merchandise, and a missing young woman. If only they can find the right bridge, they might be able to put it all together. But sometimes, a case is like a funhouse mirror at an amusement park. You have to adjust to the distortions in order to perceive the truth.
