Married FBI agents Savich and Sherlock work and play hard: devoted to their jobs, their son, and each other, they approach each new case with gusto, and appreciate every moment of downtime they can grab.

But a long weekend getaway at a secluded cabin in the Pennsylvania woods is cut short when the agents are summoned back to Washington, where a nightmare awaits them: The night before the Supreme Court is to hear opening arguments in a highly controversial death-penalty case, a prominent judge is murdered in the court's third-floor library.

Savich and Sherlock are charged with heading the investigation but when the killings continue, each targeting another brilliant, successful Washington power broker, the agents are faced with their most baffling and shocking case of their lives.
