Without Consent (Helen West Mysteries, Bk. 6)

Prosecutor Helen West's relationship with police officer Geoffrey Bailey is becoming more serious, but the couple is at odds because Bailey's protégé, Sergeant Ryan, is suspected of rape. As the evidence slowly mounts against Ryan, West and Bailey examine the seemingly open-and-shut case; a terrible crime warrants justice regardless of their feelings toward Ryan. But as they dig deeper, a new suspect emerges - one who possesses a cold-blooded intuition about women. West and Bailey quickly find themselves trying to clear Ryan's name and avenge a series of crimes with no evidence.
