THE CSI'S ATTEMPT TO DETERMINE WHETHER OR NOT FOUL PLAY WAS INVOLVED IN A HOUSEWIFE'S DEADLY FALL DOWN A FLIGHT OF STAIRS, ON A REBROADCAST OF "CSI: CRIME SCENE INVESTIGATION," THURSDAY, DEC. 15

"Bite Me" -- The CSI team investigates a wife's suspicious death on a flight of stairs, on a rebroadcast of CSI: CRIME SCENE INVESTIGATION, Thursday, Dec. 15 (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. (Originally broadcast 10/6/05; previously scheduled for a later date)

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.
