The body of a woman who worked as a book restorer for a historical society is found in the metal cage used to protect rare volumes. In their efforts to determine if the death was from natural causes or murder, Grissom (William L. Petersen) and Nick (George Eads) receive unexpected assistance from the woman's autistic co-worker. And Catherine (Marg Helgenberger) and Sara (Jorja Fox) investigate the fatal crash between a train and an SUV, a tragedy that might have been the outgrowth of road rage. ~ Hal Erickson, Rovi
