The Masked Woman(1927)

Baron Tolento lusts for Diane Delatour, his physician's wife, and donates money to their favorite charity, a children's home, in hope of gaining her favor. When Delatour is called away, Tolento inveigles Diane into attending a party at his house. There he threatens to ruin her husband if she does not submit to his demands within three months. Diane retaliates by showing him a letter proving that Tolento has only three months to live, according to a specialist. Delatour learns of his wife's presence at the party from one of the baron's women, and when Tolento makes Diane heir to his fortune, he becomes convinced of her infidelity.
