Called in the first scene... (SPOILERS!)
Omg the very first scene when Lee came on. I didn't even know who he was in relation to the main character...but in that first instant when he comes up the backyard porch at the house, I thought "AH, he did it." I knew he killed her.
Just some kinda cinematic clue (or his acting?) gave it away to me, I guess. Just the way he so easily cozied up to Igg, so trusted, yet to me seemed sleazy beneath that veneer...I was like yyyep this guy's the murderer. Haha. Then when they showed the flashback with the necklace and all, I was like well DUH now it's exceedingly obvious.
Anyway...Anyone else guess it from that first instant he was on screen? (Those who hadn't read the book obvs, like I haven't)
