The King In Yellow is in there because it’s a story about a story, one that drives people to madness. Everything in True Detective is composed of questionable narratives, inner and outer, from Cohle’s view that identity is just a story we tell ourselves, to the stories about manhood that Hart tells about himself, to the not always truthful story they tell the detectives investigating them. So it made sense – to me, at least — to allude to an external narrative that that is supposed to create insanity, or as I prefer, deranged enlightenment. When I did that, a kind of secondary language began to form in the scripts, where the notion of cosmic horror became a very real part of the environment, at least for those who know Chambers’ work.
