If I have this right – and I think I do – the big clue that blew the case is that Errol William Childress chased a girl through the woods wearing green ear-guards, and Marty remembered that a house they visited while investigating the Lang case was painted green, and got a hunch that the guy who wore green ear guards might have painted that house green.
That’s what happened, right? Or do I have this wrong? Did the mystery with some of the best writing I have ever seen in a TV drama NOT have the absolute dumbest, worst plot development of any crime show ever?
Also stuff that I don’t think was in the finale, but surely I missed it because how could they leave it out: why was Dora Lang positioned so the police could find her? Why wasn’t she buried at Carcosa with all the other victims? Who lit the fire? Why? And what was going on with Marty’s daughter? Y’know, that major plotline that ran throughout the entire series except for the final episode?
