"Bite Me" -- The CSI team investigates a wife's suspicious death on a flight of stairs, on CSI: CRIME SCENE INVESTIGATION, Thursday, Oct. 6 (9:00-10:00 PM, ET/PT) on the CBS Television Network. Jeffrey Hunt directed the episode from a teleplay by Josh Berman and a story by Josh Berman and Carol Mendelsohn, one of the series' executive producers.

The overwhelming amount of blood evidence in the case leads Grissom and his team to discover several revealing secrets within this "typical" American marriage -- secrets of adultery, blackmail and a biting fetish that may have ultimately contributed to the housewife's death.
