When a retired colleague dies of an apparent suicide, ex - Secret Service agent Joe Reeder knows there must be far more to the story. Why did the man leave a desperate message for Reeder moments before dying? And what could possibly make such a seasoned veteran fear for his life?

FBI Special Agent Patti Rogers has a mystery of her own to solve: she's leading a task force investigating a brutal series of similar but seemingly unconnected murders across the DC area. Are they serial killings or something even more sinister?

Could Reeder and Rogers be tracking down different facets of the same conspiracy? And how do the continued assassination attempts on a presidential hopeful figure into an unprecedented attack on the heart of government?

The answers to these questions are uncovered in this riveting sequel to the bestselling Supreme Justice.
