When he is in the library, he discovers an elaborately-carved bottle on a shelf; its inscription states that its contents provide a cure for the oppressions of "time and disease" and the thoughts or passions that "lead to madness." He takes a dose of the liquid, thinking it will cure his passion for Yoletta, which he doesn't realize she has begun to learn to reciprocate. It is only when his body grows stiff and cold that he realizes that the potion is a poison, and that the only relief from the pains of life it provides is death.
This story, of a traveler who falls in love with a mysterious, beautiful young girl with an elderly protector, anticipates the plot of Hudson's later and more famous novel, Green Mansions.
