THE BERLIN EXCHANGE

After a prisoner exchange lands him in East Berlin, an American physicist who'd been imprisoned in Britain for 10 years for spying for the KGB risks everything to get his loved ones to freedom.

The year is 1963. Martin Keller, a one-time Los Alamos researcher who had idealistic intentions in sharing secrets with Russia, then an American ally, learns only after he arrives in Germany that the prisoner swap was arranged by Kurt Thiele, a shifty East German who specializes in such matters and who is married to Keller's former wife, Sabine, a West German. After her marriage to Kurt, she settled in East Berlin with Peter, her son by Martin. From the start, when shots are fired at either Martin or Kurt at the checkpoint during their crossing into East Berlin, things are tense. Martin has barely settled into his new residence when Western intelligence descends on him and pressures him into working for them. He slowly realizes that the "important work" he will be doing as a physicist is not what he agreed to. After learning that Sabine is dying of cancer, he devises a plan to escape with her and Peter to get her medical treatment in the West, but how will that sit with their precocious 11-year-old actor son, who has been programmed by the socialist propaganda of the hit TV series in which he stars? In a city rife with corruption (the East Germans were selling prisoners for 40,000 Deutschemarks a head—"more if he was valuable"), no one can be trusted. But someone must be if Martin's dangerous plan is to succeed. A novel that gives paranoia a new name, Kanon's latest in a brilliant collection—including Leaving Berlin (2014) and Istanbul Passage (2012)—may be his most tightly rendered. The suspense builds quietly, almost stealthily, before tightening its grip.

Another supersophisticated spy thriller from a ranking master.
