LutherThe U.K.’s best cop drama, and one of the best to find its way over here, “Luther” (BBC America, 10 p.m.) returns for a third season that hits all at once – a new episode a night for the rest of the week and that’s it.

Idris Elba, who made his name stateside in “The Wire,” has found the role of his life a John Luther, a London detective who is brilliant but prickly, who doesn’t always follow the rules and finds himself attracted to the wrong women.

He runs into a nice woman this time, though there’s barely time for dating when he becomes immersed in a cold case serial killer even while internal affairs is watching his every move. Tonight’s caper wraps up Wednesday, and the final two episodes of the season Thursday and Friday similarly dovetail.

While UK cop dramas have trailed U.S. shows in brutality and impact, “Luther” has caught way up and excels at those jump-out-of-the-screen scary moments. And Massive Attack does the music.

“Law & Order” originator Dick Wolf unveils his latest series, “Cold Justice” (TNT, 10 p.m.), a reality true crime series featuring former prosecutor Kelly Siegler and former CSI Yolanda McClary, who are referred to as a”the real life ‘Rizzoli & Isles'” (TNT, 9 p.m.).

It’s one thing to drop a bunch of pounds as they have been doing all summer on “Extreme Weight Loss” (ABC, 8 p.m.), which has its season finale tonight. But sometimes, losing weight, doesn’t give full satisfaction. It has to come with getting back at the people who teased you when you were fat. Hence, the new series “My Big Fat Revenge” (Oxygen, 9 p.m.) in which the newly slimmed down prank their former bullies, be they bad ex-boyfriends or mothers who were full of put-downs.

Another 12 semi-finalists try to get to the finals on a two hour “America’s Got Talent” (NBC, 9 p.m.).

It’s down to the final four, meanwhile, on “So You Think You Can Dance” (Fox, 8 p.m.).

A new season starts for the stateside “Top Gear” (History, 9 p.m.), with Adam Ferrara, Tanner Foust and Rutledge Wood racing from New York to Los Angeles.

“Heroes of Cosplay” (Syfy, 10 p.m.) has turned out to be a pretty entertaining reality show.
