Der nachtliche Lehrer

the long version

"In a small town in the far north of Sweden, Lennart begins a job as a teacher. He married the librarian Elizabeth, who shortly thereafter dies in an accident. After that Lennart is a complete loner who spends his days on prehistoric grave mounds and eventually gives up his work. But sometimes he comes back at night to the school house, like a gentle ghost who seeks his life."--Cataloger translation of publisher description.
