Question: Can you give me some Without a Trace scoop?

Answer: The show's crossover episode with CSI will kick off November sweeps. "It's about a serial killer that goes across the country," explains CSI boss Carol Mendelsohn. "We've had the story in our back pocket for a couple of years, and now that WAT is back on Thursday nights, it's perfect." Mendelsohn adds that the gimmick was "spawned out of the relationship between Anthony LaPaglia and Billy Petersen and [CSI producer/director] Danny Cannon; they've all wanted to work together."
