Henry deserts and heads for Milan where he learns that Barkley, pregnant, has left for Switzerland. In Switzerland, Barkley is equally frustrated by the lack of correspondence from Henry. When her mail to Henry is returned to her, she collapses in shock, suffers a miscarriage, and becomes gravely ill. Henry finds her at the hospital and they profess their love as she dies in his arms.
