CSI: Miami (2002)

Season 1: Episode 12

Horatio and Speedle investigate the slaying of a hooker who is found dead under a bed in a plush beachside cottage, her naked body having been stabbed 23 times. But the crime scene yields few traces of blood because the killer bathed the victim in the cottage's tub with cardamom soap. Across town at an urban gas station, Calleigh and Delko attempt to uncover why a German tourist was gunned down in an apparent carjacking. They learn that a masked assailant approached a vacationing couple's rental car, shot and killed the husband, but left the wife unharmed and then fled the scene.
