A White House Secret Service agent specializing in electronic surveillance has been blown away by a masked gunman. The Aryan Clan, a neo-Nazi group, has taken credit. Secret Service Special Agent Pete Garrison fears it's more than a warning shot delivered by extremists. His first lead is an informant who claims that the Aryans have positioned one of their own in the White House. But it's the second lead that carries the most shattering implications - a blackmailer who knows of Garrison's love affair with the First Lady. He has the photos to prove it: evidence that would frame Garrison with the perfect motive for murder.

Garrison's last option: infiltrate the President's most powerful circles of defense…and outguess the killer's next move.
