The Case of the Mossy Lake Monster (Doyle and Fossey, Science Detectives) / Michele Torrey

Is there a creepy creature lurking in Mossy Lake? Is an evil plot stirring? Is something shocking happening to Caitlin’s cat Zappy—and can he be de-zapped? Would-be scientists and detectives will want to slip into their lab coats, dust off their test tubes, and get on the case with Drake Doyle and Nell Fossey.  Hint: to find the answers, kids will have to use such scientific principles as buoyancy and static electricity.
