What it feels like
Reading this novel feels like being trapped in a damp, smoke-filled room where the air is thick with exhaustion and paranoia. It is a cerebral and deeply atmospheric experience that immerses you in the grueling, unglamorous reality of wartime intelligence. The narrative moves with a brisk, ticking-clock urgency, balancing the intricate, almost obsessive mechanics of code-breaking with the visceral dread of lives lost at sea. You can feel the damp English chill and the crushing weight of responsibility on the characters' shoulders. It delights readers who want their historical thrillers to be as intellectually rigorous as they are suspenseful, offering a shadowy world where trust is a liability and every mathematical breakthrough carries a devastating human cost.

About the book
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 lives of Allied sailors are in 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....
Until the unthinkable happens: the Germans have somehow learned that Shark has been cracked. And they've changed the code....
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....
