Washington, D.C., Metro Police Detective Sergeant Sam Holland 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 she's assigned to the case. Things get complicated when she has to team up with Nick Cappuano, O'Connor's friend and chief of staff…and the man she 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.
