1) “FBI” season-finale, 8 p.m., CBS. A bio-weapon has been stolen from an unwitting defector. Now the FBI must link with an old foe, rushing (shown here) to prevent an outbreak in New York City.
2) “CIA” season-finale, 9 p.m., CBS. Colin and Bill race to catch an intelligence firm before it can hide its stolen data. At the same time, they try to capture a dangerous person from Colin’s past. Another hour reruns at 10.
3) “You’re Killing Me” debut, www.acorn.tv. Here’s the charming arrival of a mystery-solving duo. These two differ in age (played by Brooke Shields, 60, and Amalia Williamson, 31), height (6-foot and 5-4) and personality. An oft-married mystery writer teams with a free-living novice. The mysteries are so-so, but the characters are a delight.
4) “Sullivan’s Creek,” 8 p.m., CW. And here’s Williamson’s previous show, an amiable drama set amid Canadian beauty. Maggie, a doctor, struggles to find what’s causing Tracy’s fever. Also, Liam — sort of her ex-husband, except the divorce paperwork didn’t go through — finally comes clean about their past. Also, Cal finds Ben hasn’t been honest.
5) ALSO: For fun, there’s “The 1% Club” at 8 p.m. on Fox, a “Wild Cards” rerun at 9 on CW (a copycat killer visits a town’s grisly anniversary) and Steve Martin films on Turner Classic Movies. “Dead Men Don’t Wear Plaid” (1982) and “The Jerk” (1979), at 8 and 9:45 p.m. ET, are gems; “Pennies From Heaven” (1981), at 11:30, isn’t.
