Detective Veronica "Ronnie" Chase is good at her job.

Following in her father's footsteps, she dedicates herself to seeing justice served. The death of one prostitute changes things for Ronnie, when it is discovered she is now the target of a madman's desire. With this threat over her head, the last thing she needs is a new partner. However, her current partner has issues, and Ronnie needs someone she can count on.

Detective Danny Monroe is the perfect man for the job, and so much more than Ronnie could have imagined, not to mention the poster boy for sexy. As things heat up between the two, more victims fall, and with each a killer draws Ronnie closer to him. Closer than expected.

"Goodnight, Sweetheart" are no longer words of love, but the signature of a killer.
