The Crystal Hunters

A tense tale, such as we expect of George Manville Fenn. A group of English people are in the Swiss Alps. But it is not just the beauties of the scenery they are after, but crystals which may sometimes be found in caves near the top of the glaciers. They manage to find a guide who promises to be discreet about what they do. But someone else is on the mountain, and he is just as interested in what they are up to, and what they find, as they are themselves.
