International bestselling author Peter D. Johnston has crafted a critically acclaimed thriller wrapped in the history of a moated castle, the Holocaust, and Hitler’s rise—inspired by new accounts of how the Nazis tested a fledgling nuclear weapon in late 1944.

Recovering from gunshot wounds and confined to an ancient English castle, America's top negotiator shares the secrets of his interrupted mission and his craft with the only person he dares to trust—a young British nurse with a troubled past. When she proves to be an exceptional student of his laws of influence, he urges her to help him complete his mission: Hitler has an atom bomb, and his scientists must be persuaded to undermine their own creation.

Weapons of Peace races from a midnight ambush on a British beach and a bizarre killing in Washington, D.C., to a scorched atomic test site in Germany and hidden passages forged under Berlin by resisters plotting to murder Hitler. Johnston's expert hand blends real-world historical material with heart-pounding action, unforgettable characters, and precious insights into influence and how the Nazis negotiated their way to power and kept it.
