location (spoilers)

i quite like this version. but what baffles me is the fact that no one(except Frau Grohmann) thinks of leaving(unless of course they all think it was an accident of some sort) but why doesn´t Herr Grohmann tell the rest of the group he will try to climb down the mountain? if he had done so they automatically would have been forced to spent the day together to make sure none of them can kill him

plus: i just cannot believe anyone would wait in the freezing cold outside and not go inside when wargrave wouldn´t show up
