Michael Weston is paid well to do his work and ask no questions. When you're a professional assassin, total secrecy is part of the job. But after a successful mission in London, the police are immediately on his tail. How did they know how to find him? And who is his anonymous employer? Why did he or she want his target, a TV reporter, killed? Was he set up from the start? The questions lead Weston to his nemesis Hoffer, a private detective who has been hunting him for years. Ever since Weston accidentally killed an innocent American girl, her grieving father has employed Hoffer on a relentless mission to bring Weston to justice. Could Hoffer finally have set a snare that worked? Weston sets out to find his mysterious employer, traveling from London to Glasgow to Seattle-even if it means encountering Hoffer face-to-face at last. With the brilliant eye for character and taut pacing that have made him an internationally renowned bestseller, Ian Rankin delivers a gripping story that examines what happens when the assassin becomes the target, and proves yet again that "in Rankin, you cannot go wrong" (Boston Globe).
