Watch Your Wife (1926)

Writer James Langham and his wealthy wife, Claudia, quarrel and are divorced. Claudia moves into a posh hotel and renews her acquaintance with Alphonse Marsac, an old European friend with an eye on her fortune. Alone in the family mansion, James goes to an agency and rents a "wife" to be his daytime companion and housekeeper. Claudia finds them together one evening, and, suspecting the worst of an innocent relationship, impulsively informs Alphonse that she will marry him. James goes after her, sweeps her from a moving train, and marries her for the second time.
