Accidental Heroes

On a beautiful May morning at New York’s John F. Kennedy airport, two planes have just departed for San Francisco—one a 757, another a smaller Airbus A321. At a security checkpoint, TSA agent Bernice Adams finds a postcard of the Golden Gate Bridge bearing an ambiguous—perhaps ominous—message. Her supervisor dismisses her concerns, but Bernice calls security and soon Ben Waterman arrives. A senior Homeland Security agent, still grappling with guilt after a disastrous operation in which hostages were killed, Ben too becomes suspicious. Who left the postcard behind, which flight is that person on, and what exactly does the message mean?
