The Girl in a Swing (1988)

A London art broker goes to Copenhagen where he requires the services of a secretary fluent in Danish, English, and German. He falls deeply in love with the woman, despite the fact that he knows virtually nothing about her. She insists on not being married in a church, and after they are married, some bad things from her past begin surfacing in subtly supernatural ways, and he must find the best way to deal with them without destroying their relationship.
