Mystery in Mt. Mole — Richard W. Jennings

Assistant Principal Jacob Farley had disappeared, but as Mt. Mole's least-liked citizen, no one in town seemed to be in any hurry to find him or his captor. So thirteen-year-old Andrew J. Forrest takes on the investigation himself, discovering along the way many buried secrets about his hometown, its population, and most explosively, about the town's namesake hill, Mt. Mole itself.
