Elementary 10 p.m., Channel 4

It’s funny, almost, to see CBS fitting Sherlock Holmes into a procedural box, with ongoing and slowly unfolding back stories. It’s as if the idea of this show were a result of “The Mentalist,” instead of the other way around. Tonight, the series begins introducing the parents, specifically Joan Watson’s mother, who is not supportive of her daughter’s decision to become a sober companion. Freda Foh Shen, from “JAG” and “Close to Home,” will play Mama Watson. Who’ll play Sherlock’s yet-to-be-cast dad? Malcolm McDowell? Above (from left): Shen, Stephen Park, Jennifer Kim, Jonny Lee Miller, Lucy Liu.

Panic 9-1-1 10 p.m., A&E

Part manufactured thriller, part exploitation reality series, “Panic 9-1-1” takes actual emergency calls and dramatizes them. “There’s somebody in my house. . . ” “Hurry, she’s drowning. . . ” “My ex-boyfriend is following me in a car. . . ” We hear these real, desperate pleas, and then see lots of gritty re-creations and interviews with relatives of the callers — and, maybe, the callers themselves. If they survived, mwahahaha.
