True Detective season 4 is hiding an Easter egg that connects to the first season's big mystery

It’s time to get those conspiracy boards out again. True Detective: Night Country’s opening features a quote that, on first showing, may not seem like much – but it’s actually got ties to the acclaimed first season of HBO’s crime anthology series.

"...For we do not know what beasts the night dreams when its hours grow too long for even God to be awake," reads the epigraph at the start of Night Country’s premiere. 

The line is attributed to ‘Hildreg Castaigne’. Don’t worry if you haven’t brushed up on your 19th Century literature, as Twitter user _JudyRuliani has done some digging.

"The opening quote is attributed to a 'Hildred Castaigne', who is the protagonist and narrator of the short story 'the repairer of reputations' by [Robert] W. Chambers which is featured in his 1895 collection titled 'the king in yellow'," the user writes.
