Three-week visit becomes seven years
Hans Castorp, a young Hamburg engineer about to start work at a shipyard, travels up to a Davos tuberculosis sanatorium to visit his cousin Joachim for three weeks. A doctor then finds a slight moist spot on his lung, and he stays for seven years inside a closed routine of meals, balcony rest cures and thermometer readings, while his romance with Clawdia Chauchat and the arguments of his mentors keep him there. He comes down only when the First World War breaks out in 1914, and the novel's last sight of him is as a soldier on a battlefield, where he may be killed.
