Question: Will there really be a murder mystery on Las Vegas during sweeps?

Answer: (SPOILER ALERT) You've got it half right. Yes, someone will get murdered in the Nov. 28 episode, but there will be no mystery who did it. NBC will have my head if I tell you who gets whacked, but here's a hint: If the Vegas cast were divided into two camps youngish and oldish the victim would fall into the latter camp. And here's another potential clue: In that same episode, Dean Cain will reprise his role as Sam's ex and stay on for at least one more episode. Hmmmm....
