"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
