Lois Duncan’s 1974 Down a Dark Hall is a young-adult gothic novel.
Kit Gordy’s widowed mother has found new love and Kit has become a temporary inconvenience. There is no place for a teenage daughter on the newly married Mr. and Mrs. Rolland’s European honeymoon, nor are the Hollands inclined to leave Kit on her own. Madame Duret’s upstate New York Blackwood School for Girls seems to offer a sensible alternative. While her mother and stepfather explore their new marriage together, Kit will enjoy a transformative education.
Perhaps enjoy is the wrong word.
