What’s on TV

STUMPTOWN 10 p.m. on ABC. A pair of hairy kidnappers discuss the origins of the beans in a cup of coffee (“It’s tart, but it has an earthy finish — I’m going with Ethiopian”) in the first episode of this new crime drama, which is set in Portland, Ore. Based on a comic book series by Greg Rucka and Matthew Southworth, the series stars Cobie Smulders (“How I Met Your Mother,” the “Avengers” movies) as Dex Parios, a private investigator with a military background and an uneasy mind. “Assuming Dex has weekly cases, they’ll need to tighten up; the pilot’s kidnapped-girl plot is expository filler,” Mike Hale wrote in a review for The New York Times. “There’s a potentially appealing mix of wisecracking humor and underplayed, credible action, though, that could blossom if it’s given precedence over the melodramatic back story.”

THE MASKED SINGER 8 p.m. on Fox. Who were those masked singers? That’s a question some viewers were asking — not necessarily happily — after extravagantly costumed contestants from this weird competition show popped up again and again during the Emmy Awards on Sunday night. They’ll have to wait for an answer: The show pits singers with varying degrees of celebrity against each other, their identities hidden by crazy costumes. The first season’s winner was eventually revealed to be T-Pain in a monster get-up. The second season, debuting Wednesday, will bring a new set of contestants.
