Scat - Carl Hiaasen

Mrs. Bunny Starch, the most feared biology teacher ever, was last seen during a field trip to Black Vine Swamp. The school's headmaster and the police seem to have accepted the sketchy, unsigned note explaining that her absence is due to a family emergency. Theres no real evidence of foul play. But still, Nick and Marta don't buy it. Something weird is definitely going on.
