Science super-sleuths Drake Doyle and Nell Fossey are back—this time in a never-before-published addition to the popular series! They’ve got an exciting collection of cases, too: Are ghosts and ghouls keeping Edgar Glum awake? Have aliens invaded Mossy Swamp? What’s the crooked game everyone’s losing at the carnival? And why is the town bridge going bananas? Kids will have fun following the clues—and learning about such real scientific principles as amplification, ecosystems, magnetic fields, and more. Plus, budding Doyles and Fosseys will find actual experiments to try!
