Nevertheless, he receives weekly visits—specifically from Christopher Hollberg, the man whose life he supposedly destroyed years ago by stalking him, which drove Hollberg's wife to suicide. The arrangement is said to benefit both parties, as Natalie is assured that they are very fond of each other. However, the young woman soon becomes disturbed by the open disdain with which Hollberg treats his supposed friend. She tries to uncover the mystery behind the inscrutable visitor and understand his motives. This novel is a journey into the world of Clemens J. Setz, revealing its inner order.
