Steinbeck wrote The Pearl based on his personal convictions, and based the story on the biblical parable of a ?pearl of great price.' In this story, a jewel for which the merchant trades everything he owns becomes the metaphor for Heaven. Everything in the merchant's earthly existence, however, becomes worthless when compared to the joys of living with God in Heaven. However, Steinbeck uses the parable as a meditation on the American dream of success. Steinbeck, who himself had risen quickly to prosperity, explores how Kino , the protagonist of The Pearl, deals with his newfound prominence in the community and riches.
The trackers are slow in their pursuit and finally arrive at the watering hole at dusk. They make camp nearby, and two of the trackers sleep while the third stands watch. Kino decides that he must attempt to attack them before the late moon rises. He strips naked to avoid being seen and sneaks up to striking distance. Just as Kino prepares to attack, Coyotito lets out a cry, waking the sleepers. When one of them fires his rifle in the direction of the cry, Kino makes his move, killing the trackers in a violent fury. In the aftermath, Kino slowly realizes that the rifle shot struck and killed his son in the cave.
