Although the death of the wife of millionaire Las Vegas casino owner Daniel Thorn (James Brolin) has been ruled accidental by the local authorities, Captain Stottlemeyer (Ted Levine), who's in Vegas to attend a bachelor party, suspects foul play--and accordingly, calls Monk (Tony Shalhoub) onto the scene. Monk agrees that Mrs. Thorn's demise was no accident, but is stymied by a contradictory clue: How could the victim have been heard screaming for her life if she died of strangulation? And elsewhere in Sin City, Stottlemeyer's assistant Lt. Disher (Jason Gray-Stanford) is trying his luck at the blackjack table--but the luck is all bad until Monk shows up and pulls a "Rain Man" with his photographic memory!
