1) “The Bachelorette,” 8-10 p.m. , ABC. It’s almost time for the final four guys and home-town visits, but two still haven’t had one-on-one dates with Katie Thurston (shown here), 30. Brendan Scanzano, 26. is a firefighter trainee; Mike Planeta, 31, is a gym owner. The others: Blake Moynes, 30, wildlife manager; Greg Grippo, 27, sales rep; Justin Glaze, 26, investment salesman; Michael Allio, 36, business owner; and Andrew Spencer, 26, who has spent three pro-football seasons as a defensive back in Austria.
2) “The Beast Must Die,” 10 p.m., AMC. “Remember this feeling,” a man tells his devastated son. “It’s what you do after this that counts.” Everyone in this richly layered, six-week drama seems to be back from devastation. A cop, whose colleague was killed, has taken a job in a remote village. A teacher, whose son was killed there by a hit-and-run driver, has changed her identity and moved there. In last week’s opener, she met a troubled beauty, connected to a crashed car; tonight, she makes key progress.
3) “Bob (Hearts) Abishola,” 8:30 p.m., CBS. Ater stuffing its summer with reality shows, CBS bunched its three excellent Chuck Lorre comedies on Mondays. Now each has one of its better reruns. First, Bob wants to buy a ring for Abishola; her uncle – who considers himself a master at haggling – helps, sort of. Then “Young Sheldon” sees freshman orientation go awry. And on “United States of Al” (9:30), Al and Riley are asked to speak to a veterans’ group; the laughs are sparse, but there are moving moments.
4) “American Ninja Warrior,” 8-10 p.m., NBC. Starting Friday, the Olympics will consume NBC. Now some of the summer ratings-leaders get their last chances for a while. Tonight, the “Ninja” semi-finals begin, including two new obstacles; on Tuesday, “America’s Got Talent” has its eighth audition round.
5) “Ms. Fisher’s Modern Murder Mysteries” season-finale, any time, www.acorn.tv. A New Year’s Eve party prepares to greet 1965. Peregrine is there; so is the cop she broke up with, even though they’re gaga for each other. Then, of course, there’s a murder. The solution is quite lame, as usual, but everything else – the fashions, the décor and the Beatles-style band – reflect early-’60s joy. Acorn also has the other seven films from a fun season … plus a new episode of the serious “Jack Irish.”
