The ski lodge/4

Well, looks like the winner suspicion was wrong. Whoops.

Look like things turned for the worst for Nicholas. He was found in the library. Apparently, he was reading a crossword book when the murderer removed the back of his wheelchair (to make him fall and become immobile), and dropped a bookcase on him. It is still a mystery how the murderer is doing all these crimes silently. Even if everyone was asleep, someome would hear this.

4 down, many to go. We can only guess who will be next...
