"December, 1942. Conor Thorn will stop at nothing to end Hitler’s terror. So when a brilliant nuclear physicist is discovered holed up in Italy, the elite OSS agent reunites with his MI6 counterpart and slips behind enemy lines on a recruitment mission. Now pitted against rival forces also on the hunt, Thorn is hell-bent on preventing the key to an atomic weapon from falling into ruthless Nazi hands. With the clock ticking on the escalating war, his operation falls under threat when his objective proves elusive. And as Russia, a double-dealing Italian monsignor, and the Vatican all converge on the reluctant theoretician’s hideaway, Thorn struggles to keep clear of an ever-tightening deadly trap."
