The Strange Likeness

Classmates in a girls’ school on the shores of Lake Michigan, Shirley Harcourt, from an eastern state, and Sidney Thorne, whose home is in Chicago, bear a remarkable resemblance to each other. At first they resent the likeness, but afterwards become very good friends, and often wonder about their lineage. At last Sidney discovers she is an adopted child, and her foster father traces her parentage very carefully to find she is indeed the twin sister of Shirley.
