In the valley the world's best "eternal triangle" is being worked between a husband, a much younger wife and "one who covets." On the heights, the shepherd hears the call and for the nonce becomes a wanderer, and descends into the valley of Passions and Pain. It is the gentle, unfelt, almost unseen influence of the wanderer that stops a maddened husband from first murder and then suicide; exposes the frailty of a wife to her own consideration, and points out to her the grim consequences of a moment's folly, and finally takes the "one who covets" away from the born passions of the valley a far journey up the heights, and disaster to three souls.
