Mystery on Echo Ridge

High above the town of Highwood is Echo Ridge -- a cold, dark hillside on which stands the mysterious Lampier house. It has been boarded up for years, but now Mrs. Lampier has come back to Highwood to live. David Hughes, his sister Barby, and their friend, Jon Vickery, find themselves much too involved with the strange old house and its inhabitants to feel really comfortable near Echo Ridge.
Not until blue lights in an empty window, a ghostly apparition in a cemetery, the disappearance of a valuable necklace, and an old, old crime have been explained can the three children relax and be sure they will continue to be happy in Highwood.
This is one of Mary C. Jane's most exciting mysteries. Boys and girls will recognize and sympathize with her well-drawn characters, and the fast-moving plot will keep them guessing until the last chapter.
