"Redrum" -- Catherine must deceive her teammates when she agrees to Keppler's covert and controversial plan to catch the killer of a popular politician, on CSI: CRIME SCENE INVESTIGATION, Thursday, Jan. 25 (9:00-10:00 PM, ET/PT) on the CBS Television Network. Martha Coolidge directed the episode from story by Richard Catalani and David Rambo and a teleplay by Jacqueline Hoyt and Carol Mendelsohn, one of the series' executive producers.

Tony Award winner Liev Schreiber ("Glengarry Glen Ross," "The Manchurian Candidate," "RKO 281") returns as Michael Keppler, a seasoned CSI who is new to Las Vegas and is assigned to Grissom's team during Grissom's teaching sabbatical.

The leading suspect for the high-profile murder of anti-drug crusading assemblyman Danilo Zamesca is Thomas Simon, the west coast's biggest drug supplier, whose trail quickly grows cold. Catherine agrees to Keppler's unconventional method to find Simon, despite her reservations about lying to her longtime CSI teammates, who soon sense that something is awry.
