His Neighbor's Wife (1913)

Mr. Norton discovers his wife in the arms of his neighbor, Captain Roberts, a married man. His first maddened impulse is to kill his faithless wife, but on his way for the gun his little child runs to his arms to say good-night. The incident unnerves him and his wild determination is destroyed. He decides upon another course. He goes to Mrs. Roberts and tells her that he intends to ruin the Captain's home as her husband had ruined his, and that unless she consents to elope with him at ten o'clock that night he will shoot her husband on sight.
