Mr. John Wiltz is extremely fond of his secretary, Herbert Van Kirkland, which causes jealousy among the other employees. They plot to have their employer hear evil things of the secretary, and Van Kirkland is discharged. The newspapers expose a shady transaction which had been supervised by Wiltz, and the only witness, Van Kirkland, is gone. Wiltz is snubbed by all his former friends. A year later we see him addicted to drink, sick and alone, all on account of listening to "he who speaketh evil." Moral: do not convict until justly tried.
