The Invisible Bond.

Seductress Leila Templeton lures Harleth Crossley into a supposed assignation at his wife Marcia’s dinner party making a fool of them both. Following other compromising situations and his declaration of needing “personal liberty” Marcia divorces him. Still enamored of Leila, he marries her, but she remains a selfish flirt and Otis Vale, whom Leila has driven insane with her teasing, abducts her. In the mad dash away their automobile tumbles over a cliff, killing them both. When Harleth learns that "Mrs. Crossey" has died, he imagines it to be Marcia, and rushes to her. The relief he shows convinces her that their "invisible bond" is intact, and they reconcile.
