Spectres of the Black Sun. The Black Sun Cycle, #2

The war is over, and Major John Hartman has left active duty. He and Sergeant Margie Bywater have gotten married and are looking forward to the next stage of life, come what may. But rest doesn't come easily to heroes when Colonel Spivey, formerly of the OSS and now CIA, appears unannounced to recruit the newly married couple into America's new cause - the clandestine fight against Communist oppression.
But a literal wrong turn finds John Hartman on an idyllic suburban street in the suburbs of Washington, D. C. to find a woman covered in blood running frantically his way. He suddenly finds himself embroiled in a murder kidnapping, a crime with improbable connections to ghosts he thought he left behind in the war.
