Operation overlord: the most carefully guarded secret of the war, and the Allies' ultimate victory depends on its remaining so. But one of the trusted military planners who knows the where and when of the assault has fallen prisoner to the Nazis—and the success of the D-Day invasion rests with a former cop from Oklahoma.

One of "Wild Bill" Donovan's most dedicated acolytes, Captain James Cantrell, has been hand-picked for the mission of a lifetime. But the clock is ticking—and the officer Cantrell must rescue is lost behind enemy lines, in a labyrinth of lies, treachery, and lethal double-cross. And one wrong step could spell unthinkable disaster . . . for Cantrell and the Allied cause.
