The Sentinel — Gerald Petievich

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 staff. But it's the second lead that carries the most shattering and personal implications--a blackmailer who knows of Garrison's 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 desperate option: Infiltrate the President's most powerful and intimate circles of defense...and outguess a killer's next move.
