Quentin believes that Margo Roth Spiegelman has run away from home, and is leaving him clues to her whereabouts. With his friends, Ben and Radar, Quentin investigates a paper trail (a Paper Towns paper trail) left by Margo, including her highlighted copy of Leaves of Grass by Walter Whitman, that leads them to an abandoned mini-mall. When the trail goes cold, Quentin worries that Margo Roth Spiegelman's body has gone cold, too. What if she committed suicide just like the man they found nine years ago?
