The Sentinel

Pete Garrison is a U.S. Secret Service agent who saved a president's life by jumping in front of a hail of bullets, over twenty years ago.Well-liked and respected by his colleagues in the Secret Service, Garrison is a career agent who now heads the First Lady's detail. He lives in a high-level, orderly world of hierarchical structure, plans, maps, motorcades, code names, lingo and procedures. It's a universe that makes sense, until secrets begin to tear it apart. Pete's fellow agent and friend, Charlie Merriweather, hints at wanting to share critical and confidential information. Before that can happen, however, Merriweather is shot dead at his house in a crime that is made to look like a botched robbery. The investigation falls to the Secret Service's top investigative agent, David Breckinridge, a volatile combination of by-the-book and hothead, Garrison's protÉgÉ, and, until recently one of Garrison's best friends. Breckinridge follows the evidence and only the evidence and scrupulously tries to avoid working from his gut. That's what being a great investigator requires. Garrison, as perhaps the greatest protective agent in the service, often has to work from gut, from pure instinct. In protective work that is often all you have. Garrison's and Breckinridge's recent falling out was triggered by Breckinridge's mistaken belief that Garrison was having an affair with Breckinridge's now ex-wife.
