The Truth About Husbands (1920)

Socialite Leslie Brown, little more than an innocent schoolgirl, becomes engaged to wealthy playboy Dustan Renshaw who has broken his engagement with Janet Preece in order to marry a woman of breeding. After they are married, the Renshaws live abroad where one day, in her husband's absence, Leslie welcomes her friends the Stonehays as her guests, accompanied by their private secretary, Janet Preece. Janet's sudden illness compels her to remain with Leslie after her employers have departed, and the two women become fast friends. Leslie learns the story of Janet's betrayal by a man known to her only as "D. R.," and is shocked to learn upon Dustan's return that Janet's betrayer was none other than her own husband. Leslie leaves Dustan, but, with the passage of time, husband and wife are reunited at Janet's deathbed when Leslie learns to forgive her husband's past.
