Silent Night Stakeout (Harlequin Intrigue #1236)

All Regina Garrett wanted this holiday season was some R & R. What she got was mixed up in a murder investigation, and the personal protection of a very sexy homicide detective....Marcus couldn't help wondering just what Regina knew about the case that practically landed in her lap. But between her direct connection to the evidence he'd uncovered and the threats against her, Marcus also knew she needed his help if she was going to stay alive. Convincing her it'd be safest if he stayed on her couch, Marcus prepared for a string of sleepless nights. As a cop, having Regina a few feet away was smart. As a man, it was pure torture.
