@wallhackio The mousetrap is a play Agatha Christie wrote. At the end of the play when the actors come out they ask the audience not to reveal the twist(s)/ culprit(s). (I'm sure you could find out who it is if you search online though.)
The mountain I mentioned like most mountains in that area are sacred to the local people and the first (known) people to summit it made a promise to the local peoples to stop short of the summit to not tarnish it and supposedly every mountaineer since has kept that vow
