The Broken Gate(1927)

In the small farming community of Spring Valley, young Aurora Lane has caused a scandal by bearing a son by townsman Lucius Henderson, who refuses to marry her or even admit that he's the father. Shunned as a "sinful" woman by most of the town, she turns over her son, Don, to be raised by Miss Julia, the town librarian, who tells the boy that she's his "aunt". Don grows up and goes to college, and when he comes back home the town gossips begin a rumor-mongering campaign. When the town policeman tries to drive Aurora out of town he is found murdered, and Don is arrested for the crime.
