1) “American Idol,” 8-10 p.m., ABC. The Hawaiian week (shown here with Eise Kristine) is over now and some serious cuts begin. Tonight, we learn which of the 20 singers were in the viewers’ top 10; then the judges add two more. That collides with “The Voice” (8-10 p.m., NBC), which continues its “knockout round.”
2) “Dalgliesh: Death of an Expert Witness,” www. acorn.tv. One of fictiion’s great detectives is back. Adam Dalgliesh is a widower and a poet, a cop whose face barely reveals his deep soul. At the core of 14 P.D. James novels, he’s been played by Roy Marsden, Martin Shaw and now (perfectly) by Bertie Carvel. Acorn will stream a movie-length story (shown in England as a two-parter) on the next three Mondays. This opener, a forensics-lab murder, is smart and involving.
3) “Fantasy Island,” 9 p.m., Fox. Jessy Schram (Hannah in “Chicago Med”) has a lively role, as a jilted bride in flowing white gown. But the real fun is for Kyla Pratt, the “Call Me Kat” co-star. She plays an imaginary best friend from childhood, now with a grown-up body and a pre-teen mind. It’s a so-so tale with a lame secondary story (about Ruby, the island assistant), but does provide some fun.
4) “Bob (Hearts) Abishola,” 8:30 p.m., CBS. This terrific show pauses for a rerun, before showing the season’s final four new episodes during May. Tonight, Abishola is glad Bob is out of his mid-lifefunk. He takes a road trip with Goodwin … and soon has expanding ambitions.
5) “Independent Lens: Free Chol Soo Lee,” 10 p.m., PBS. In 1973, a young Korean immigrant was arrested in San Francisco for murder, sparking waves of protest; he was freed after a decade in prison. The story doesn’t provide any convenient twists; Lee was deeply troubled, before and after this. But it demonstrates the importance of relentless justice – and shows how unreliable witnesses are if the suspect is from a different ethnic group.
