The Truth About Wives (1923)

Helen Frazer marries Harold Lawton to please her domineering grandmother. However, Harold continues his dalliance with chorus girl Letty Lorraine, and embezzles $25,000 from his employer, Howard Hendricks, to support her luxurious tastes. To protect her son, Helen enters into a financial agreement with Howard, who hopes to win her from Harold. One year later, after Harold has squandered the stolen money, he kills his employer. Helen is arrested, and as the jury announces a guilty verdict, Harold bursts into the courtroom, confesses to the crime, and swallows poison, leaving Helen free to find happiness with her loyal attorney, Alfred Emerson.
