The child's laughter curves through the sunlight, as if on wings. The stalker is more enamored than ever, but aware of Brandy's vigilance with Emily, knows a kidnapping won't be easy. Planning to gain Emily's trust, the stalker gives her a necklace—little girls love pretty things. A few days later, Brandy and Emily arrive at the park for the Children's Health Fair. When the stalker sees them enter the public restroom, the opportunity is seized.Not long after Emily's disappearance, Detective Radhauser finds her rainbow-colored sneakers in Ashland Creek, their laces tied together in double knots. Brandy's father and stepmother blame her for Emily's disappearance. Radhauser feels sorry for Brandy, but insists she stay out of the investigation. Brandy can't do that. She is obsessed with finding out who took her little sister, and why. Will Emily be found in time?
