'THIS WARTIME THRILLER WILL KEEP YOU GRIPPED THROUGH TO THE VERY END' James Swallow March, 1945. Hitler’s fate is sealed. Allied forces have crossed the Rhine and the Red Army is closing in on Berlin. The war is all but over. But from the darkest depths of the Nazi terror machine, a new danger emerges – the final, awful product of history’s most twisted minds. An ultimate act of bloody defiance against humanity itself. Four unlikely allies are the only ones who can stop the horror. RAF pilot Andrew Durban, whose medals hide deep scars of battle. Johnny Grant, his terror-stricken navigator. Sarah Lane, brilliant yet ostracised SOE spymaster, haunted by the agents she sent to their deaths. And Jan Stahl, renegade SS assassin who carries his own devastating secrets. From the deadly skies over Germany to the panic-filled streets of a collapsing Reich, they must find a way to not only uncover a nightmare vision, but to stop it becoming reality. Failure won’t just end their dreams of peace. It will end everything.
