Last night's episode of 'True Detective' proves the show is still must-see TV

HBO/

Sunday night's episode of "True Detective" was a must-see.

For weeks we've been hearing about these swanky parties with high-end escorts that take place up in the Hollywood Hills, and last night we finally got a peek inside what goes down at one of them.

Following a major shootout at the end of episode 4, in which cops Bezzerides (Rachel McAdams), Woodrugh (Taylor Kitsch), and Velcoro (Colin Farrell) believe they took down the guy responsible for city planner Ben Casper's gruesome murder, we see how the three detectives still can't shake the case.

They are now on a special task force to find the missing girl that Bezzerides was looking for at the start of the season. But the real reason is to link collusion between Vinci PD and any state departments. And it's led to Bezzerides getting access into one of the racey parties. The hope is to find some answers.

They end up getting more than they expected.

Bezzerides is driven by bus with other girls to a mansion in the hills.

It seems as a young girl this man took advantage of her.

Made even more eerie with a light and an almost fantasy score in the background, the ending of episode 6 (with only two episodes left in the season) once more sucks you back into the story, giving us advancement in plot but continuing to build the suspense of what hopefully will be a charged finale.
