Overview
"LITERATE AND SAVVY . . . BRIMS WITH WARTIME INTRIGUE." --The Washington Post Book World England 1943. Much of the infamous Nazi Enigma code has been cracked. But Shark, the impenetrable operational cipher used by Nazi U-boats, has masked the Germans' movements, allowing them to destroy a record number of Allied vessels. Feeling that the blood of Allied sailors is on their hands, a top-secret team of British cryptographers works feverishly around the clock to break Shark. And when brilliant mathematician Tom Jericho succeeds, it is the stuff of legend. . . . "A TENSE AND THOUGHTFUL THRILLER." --San Francisco Chronicle Until the unthinkable happens: the Germans have somehow learned that Shark has been cracked. And they've changed the code. . . . "SUSPENSEFUL AND FASCINATING." --The Orlando Sentinel As an Allied convoy crosses the U-boat infested North Atlantic . . . as Jericho's ex-lover Claire disappears amid accusations that she is a Nazi collaborator . . . as Jericho strains his last resources to break Shark again, he cannot escape the ultimate truth: There is a traitor among them. . . . "GRIPPING . . . CAPTIVATING ." --New York Daily News "ELEGANTLY RESEARCHED . . . Readers will find themselves perfectly placed to experience one of Britain's finest hours." --People "SATISFYING . . . Harris does a crackerjack job here, playing his characters' lives off historical events in surprising ways." --Entertainment Weekly "SUSPENSEFUL . . . FIENDISHLY CLEVER." --Detroit Free Press
