Washington D.C., 1945. Victory in the war looms, but a new fear transfixes the wartime capital. Fear of communist spies and the atomic secrets they covet. When the corpse of a Navy Intelligence officer is found on a cobblestone back alley, Lt. Voigt is called in to investigate. It's his first murder, but in the plot that he quickly begins unraveling, it won't be his last. Pursuing crosses and double-crosses, Voigt goes undercover and the fragments he discovers (a defecting German physicist, a top secret lab in New Mexico, and Uranium-235) suggest something far larger than the usual spy v. spy shenanigans. Soon enough he's in a race to identify the killer, to keep the bomb away from the Russians—and to keep ahead of his own secrets.
