Walking the thin blue line…

Detective Sergeant Sam Holland of the Washington, DC, Metro Police needs a big win to salvage her career—and her confidence—after a disastrous investigation. The perfect opportunity arises when Senator John O'Connor is found brutally murdered in his bed, and Sam is assigned to the case. Matters get complicated when Sam has to team up with Nick Cappuano, O'Connor's friend and chief of staff…and the man Sam had a memorable one-night stand with years earlier.

Their sexual chemistry still sizzles, and Sam has to fight to stay focused on the case. Sleeping with a material witness is another mistake she can't afford—especially when the bodies keep piling up.
