Plot summary
CBI is called into investigate the murder of James Meier, the manager of operations for a resort casino, whose right hand has been found straddling the borderline between California and Nevada. Was this a mob hit or someone trying to send a message? While Lisbon and team look into Meier's business dealings, Jane uses his mentalist skills at the card tables, which make him a genius player, to rake in chips while studying the players on the floor. In the end, Jane discovers Meier's son-in-law's secret life as a degenerate gambler and plays on his gambling obsession to ultimately lure out the truth.
