La sancion de eiger

The mountain’s treacherous environment seems almost like a character itself. I wonder how much the author drew from real mountaineering to craft that sense of danger.

His actions often blurred the line between right and wrong, which made me question what I would do in his place. How did others interpret his sense of duty?

The blend of adventure and espionage is unique and compelling. I’m curious whether this was based on real events or purely fictional imagination.
