In London at dead of night, George Smiley, sometime acting Chief of the Circus (aka the British Secret Service), is summoned from his lonely bed by news of the murder of an ex-agent. Lured back to active service, Smiley skillfully maneuvers his people -- "the no-men of no-man's land" -- into crisscrossing Paris, London, Germany, and Switzerland as he prepares for his own final, inevitable duel on the Berlin border with his Soviet counterpart and archenemy, Karla.

Madden is sent to a town in Surrey where a local family has been massacred in what looks like a robbery gone wrong. He finds enough echoes of his recent battlefield experiences to conclude that the killer was just one man--most likely a former soldier using a bayonet. As for motive, it could well be perverse sexual passion, that "river of darkness" to which a psychologist introduces him. We meet the killer early on, watch him as he maintains a rigid control over every aspect of his life, then stare in horror as he periodically explodes into mad violence. Unlike Madden, this man has not been severely damaged or changed by the war; he has simply used it to channel and redirect his dark river. Airth's point--that survival comes in many shapes and sizes--gives a solid foundation to an impressive leap of imagination. --Dick Adler
