Michaels Barbara. The Walker in Shadows

A trio of love stories that cross generations and centuries, a pair of historic houses that conceal old and new secret passions, and a series of ghostly appearances are interwoven to form a tapestry of complex horror and beauty.
About Barbara Michaels: Pen name of Barbara Mertz, who also writes as Elizabeth Peters. Under the name Barbara Michaels, she writes primarily gothic and supernatural thrillers. The name Barbara Michaels was chosen by her publisher since she had already published one nonfiction book on ancient Egypt, and the publisher wanted her novels to be distinctive and not be confused with her other historical book.
