'True Detective: Night Country' episode 4 preview teases more creepy spirals

The spirals have been on an ongoing mystery in True Detective: Night Country, popping up on episode 2’s frozen corpsicle as well as the roof of Clark’s creepy trailer — and it looks like we’ll be seeing more of them in episode 4.

In the one-minute teaser above we see the symbol carved on a small rock and daubed in what looks like blood on the wall of a dark room. The creepy closing words, as police chief Liz Danvers (Jodie Foster) and state trooper Evangeline Navarro (Kali Reis) stand facing something unseen in the middle of nowhere? “You’re all in the night country now.”

How to watch: True Detective airs Sunday nights on HBO/Max at 9 p.m ET/PT.
