The substitute
(Book)

"Warren Botts is a disillusioned Ph.D., taking a break from his lab to teach middle-school science. Gentle, soft-spoken, and lonely, he innocently befriends Amanda, one of his students. But one morning, Amanda is found dead in his backyard, and Warren, shocked, flees the scene. As the small community slowly turns against him, an anonymous narrator, a person of extreme intelligence and emotional detachment, offers insight into events past and present. As the tension builds, we gain an intimate understanding of the power of secrets, illusions, and memories."--Amazon.com.
