What’s on TV

BRIARPATCH 10 p.m. on USA Network. “The thing about homicides, well, most of them are damn simple,” a lawman says in the first episode of this new murder-mystery series. “But every now and then, you’ll get one that’s tricky. Like this one right here.” He’s talking to Allegra Dill (Rosario Dawson), a powerful government staffer who has returned to her fictional, very surreal Texas hometown to investigate her sister’s death. (The sister was blown up by a car bomb.) The killing is at the center of the series, but its heart may lie elsewhere: Andy Greenwald, a former TV critic who wrote the show (it’s based on the Ross Thomas novel of the same name), said in an interview with The New York Times last year that he was influenced by shows like “Twin Peaks” and “Lost.” “They all had a community of characters who you wanted to spend time with and who you’d get excited about whenever they appeared onscreen,” he said. “‘Who did it?’ is kind of the most boring question you can ask. It seems like the most important question, but it’s really just the engine that fuels the deeper dive into the weirder, richer emotional lives of the characters and the community.”

KATY KEENE 8 p.m. on the CW. The Archie Comics character Katy Keene ditches the fictional town of Riverdale for the stranger-than-fiction New York City in this new, fashion-forward musical series. A spinoff of “Riverdale,” the show reimagines Katy (Lucy Hale) and a few other Archie Comics characters as young New Yorkers chasing their dreams, which include Broadway stardom and fashion-business success.
