When the restorer Veronica Bradley is found dead in a cage in the Historical Society's basement, the only witness is the autistic co-worker Aaron Pratt that worshiped her. While investigating the case, Grissom and Nick suspects of Aaron and their boss, the curator Stanley Hunter. Meanwhile, Catherine and Sara investigate the death of Megan Treadwell, who was apparently killed when a train crashed her car in a crossroad after being hit by another car.
"Caged" is another good episode of "CSI", with two segments as usual. The one of the restorer has a good conclusion, with Grissom and Nick finding what happened. The one relative to the woman hit by a train is also great, with Catherine and Sara disclosing what have happened to Megan. My vote is eight.
Title (Brazil): "Enjaulada" ("Caged")
