Kessler portrays the dangers that agents face and how they carry out their missions---from how they are trained to how they spot and assess potential threats. With fly-on-the-wall perspective, he captures the drama and tension that characterize agents' lives. In this headline-grabbing book, Kessler discloses assassination attempts that have never before been revealed. He shares inside accounts of past assaults that have put the Secret Service to the test, including a heroic gun battle that took down the would-be assassins of Harry S. Truman, the devastating day that John F. Kennedy was killed in Dallas, and the swift actions that saved Ronald Reagan after he was shot. While Secret Service agents are brave and dedicated, Kessler exposes how Secret Service management in recent years has betrayed its mission by cutting corners, risking the assassination of President Barack Obama, Vice President Joe Biden, and their families. Given the lax standards, "It's a miracle we have not had a successful assassination," a current agent says. ,p>Since an assassination jeopardizes democracy itself, few agencies are as important as the Secret Service---and few subjects are as tantalizing as the inner sanctum of the White House. Only tight-lipped Secret Service agents know the real story, and Kessler is the only journalist to have won their trust.
