One May evening in London, Adam Kindred, a young climatologist in town for a job interview, is feeling good about the future as he sits down for a meal at a little Italian bistro. He strikes up a conversation with a solitary diner at the next table, who leaves soon afterward. With horrifying speed, this chance encounter leads to a series of malign accidents, through which Adam loses everything—home, family, friends, job, reputation, passport, credit cards, cell phone—never to get them back. The police are searching for him. There is a reward for his capture. A hired killer is stalking him. He is alone and anonymous in a huge, pitiless modern city. Adam has nowhere to go but down—underground.

Vail has resigned himself to his dismissal and is content with his life as a bricklayer. But the FBI, especially Deputy Assistant Director Kate Bannon, needs help with a shadowy group that has initiated a brilliant extortion plot. The group will keep killing their targets until the agency pays them off, the amount and number of bodies escalating each time the FBI fails. One thing is clear: someone who knows a little too much about the inner workings of the Bureau is very clever —and very angry—and will kill and kill again if it means he can disgrace the FBI.
Steve Vail's options —and his time to find answers—are swiftly running out.
