ER

Bones
8 pm/ET FOX
Most people wouldn’t willingly enter a tiger cage, unless one takes care of big cats for a living. So when the mutilated body of a doctor is found in one at the zoo after a hospital charity event, Brennan and Booth are reasonably sure the deceased had some help getting there. Adding to the mystery is Cam’s disclosure that she was once engaged to the doctor — whose teen daughter she helped raise — so the team ramps up their efforts to find the killer. Chad Lowe guest stars as one of the suspects. —Joe Friedrich

The game nears its halfway point with Days 16, 17 and 18 checked off during tonight’s episode, in which the Jalapao and Timbira tribes zero in on which members may be the next targets for elimination. At Jalapao, Taj, who is in control of a secret four-way alliance that crosses tribal lines, comes into the crosshairs of some team members, while at Timbira a few tire of Coach’s intimidating ways, which could lead to his early exit. —Tim Holland

The landmark series, now in its ninth season, celebrates its 200th episode by bringing in Oscar-winning director William Friedkin (The French Connection; The Exorcist) to scare things up.
