I think most of us, at least for what I've seen in the threads, have found the 8 links and got who is the Mystery Man. Now we have to figure out the motive.
As I said in a previous thread, with the final twist around the last murder, we should go back and review all the testimonies of our original 8 suspects/victims. Henry's statement pops up. But what really intrigues me the most is WHY DID THE MYSTERY MAN DECIDED TO KILL JESSICA AND NOT FERN? What part did Mystic Margot play in this whole thing? I mean, why did she get involved in all this? What was she going to gain with all this? And finally, how did the Mystery Man know everything he/she did? Did his/her knowledge come from his/her position or from his/her relationship with one of the victims?
