The Ice Maiden

Rudy lived close to the little town of Grindelwald in Switzerland. He lived with his uncle as his parents were both dead. Indeed, Rudy himself had almost died at the same time as his mother: while crossing a glacier, she had fallen into a crevasse while carrying Rudy, who was still a baby. When help arrived, it was too late to save the mother, but, to everyone's great joy, the baby was rescued. Or almost everyone...
The only one who did not rejoice was the Ice Maiden...
