East-West talks that may help end the dangerous Cold War are set to begin soon. This peace process will come to nothing if there is a violent crackdown on Polish dissidents who plan an uprising in Warsaw that will result in massive bloodshed.
Quiller is instructed by his secret unit within the British government to go to Warsaw in disguise, learn more about the forces at work and try to diffuse the situation. A young novice with uncertain loyalties is assigned to travel with him. They arrive in Warsaw in the dead of winter. Quiller must walk a fine line between diplomacy and deception as he mingles with both the Polish rebel underground with their d-day for overthrowing the Russian-controlled government, and those in power, with their own secret plans to wipe out all those involved in the resistance.
The fourth novel in the series, all narrated by Quiller, called by The New York Times "the greatest survival expert among contemporary secret agents".
