But Nancy's investigation takes a sinister and surprising turn when Judy's roommate is murdered. Like Judy and Nancy, the victim was tall, slim and had reddish blond hair.

Huge illegal kickbacks are at stake, and the boys discover that the dirty money could cost lives. The integrity of the FBI hands in the balance as Nancy, Frank and Joe follow a twisted trail of treachery and tragedy, bribery and blackmail... in SPIES AND LIES."
