A pacemaker should have saved oil and gas magnate Nathan Moore's life. Instead, it provided his killer with a seemingly perfect means of execution.
A bombing at one of Nathan's oil rigs days earlier indicates his death could be part of a bigger conspiracy, a web Special Agent Tori Templeton must untangle. But her first order of business is separating the personal from the professional—the victim's wife, her best friend, is one of the FBI's prime suspects.
Clearing Sally's name may be the biggest challenge of her career, but Tori finds an unexpected ally in the newest member of the task force, recently reinstated Deputy US Marshal Cole Jeffers. As Tori and Cole dig deeper into Nathan's personal and business affairs, they uncover more than they bargained for. And the closer they get to finding the real killer—and to each other—the more intent someone is on silencing them for good.
