It is June of 2002, and Jacob Martin, a Denver-based Private Detective, has been contacted by a client about a very old missing persons case. In January of 1950 the client's father, Hollis Wilson, abruptly disappeared from his home in Albuquerque and was never seen again. Hollis had been a noted nuclear scientist who had worked on the A-bomb at Los Alamos with Robert Oppenheimer. Within days the FBI assigned a Special Agent, but in the end there were no leads, no sightings, no ransom notes. The FBI theorized that Hollis had in fact been a spy, along with his colleague the infamous Klaus Fuchs, who at the time was being tried for treason in a British court. Hollis, the FBI felt, had simply gone to ground before being found out. It was, after all, the era of Alger Hiss and the Rosenbergs. The client is not buying it, however, and claims that new evidence has surfaced that could exonerate his father. Jacob, intrigued by this new development, agrees to take a look. As he visits the old scenes, however, the case takes on an unexpected dark turn, and all of a sudden Jacob is caught up in at least one gruesome murder, maybe more, and the search for a killer who soon puts Jacob's own life in jeopardy.
