The Enemy Within : It is early summer of 2009, an uneasy time in the American capital. Washington is tense over a showdown between the US and the new ruler of Libya. Laura Chapman is a Secret Service agent assigned to the White House. She is quirky, solitary, and frequently unorthodox. She is also a brilliant intelligence analyst, which explains why she has been assigned to the Presidential Protection Detail for eleven years. The CIA assigns Laura to a case that borders on the unthinkable: an assassination plot against the new president. Shockingly, the trigger man will be a member of the United States Secret Service. Since it is known that the assassin is male, Laura is not a suspect. The odds are heavily against her locating an alleged assassin within the Service, and even more heavily against her surviving the assignment. Members of her service, as well as agents in the CIA and FBI, are waiting for her to fail. As her investigation proceeds, Laura cannot shake the suspicion that there are things she has not been told, that she is being set up. In her increasing moments of paranoia, she wonders: Am I going to be the next Lee Harvey Oswald?
