"Through brilliantly etched scenes of suspense - as we follow Samson into the center of a web of treachery and deceit, as he sifts through the layers of lies, time-honored assumptions, and intramural intrigues that mask the traitor's identity - the novel moves between London and Berlin (Berlin East as well as West) until, at last, the mists of secrecy that have cloaked both past and present are dissolved... and hero and traitor collide" (dust jacket).
