The Virginian - Season 1 Episode 19 The Man Who Couldn't Die

The owners of the Bradford and Willson Transportation Co. had been contracted to build a railway line for Judge Garth and other investors but had been procrastinating in starting the project. When the Judge threatens them with legal action, they send a woman, Mrs. Wallace (Vera Miles), to spy on the Judge by becoming Betsy Garth's private tutor. Matters become complicated when the Judge falls in love with Mrs. Wallace. They become even more complicated when the Judge shoots in self-defence, Willson (David White), but can convince no one, including the police, that the man is dead.
