Britain, 1947. The war is over, but the real threat is just beginning.
Joseph Stalin has a new weapon—chaos—and he’s sending his most ruthless operative to deliver it. His mission: protect a communist mole buried deep inside British intelligence. That mole holds the secret to the atomic bomb.
MI5 officer Freya Bentall knows there’s a traitor in their ranks. With trust eroding and time running out, she turns to Cambridge professor Tom Wilde, a man with no allegiance except to the truth.
Wilde is tasked with getting close to three suspects. To do that, he must enter the criminal underworld, the elite art scene, and the darkest corners of British politics.
One wrong move means national catastrophe. And Wilde isn’t just fighting for a country, he’s fighting for his family.
