Help! Just before the science fair, a set of magic potions disappear from Luna's locker! The Chicagoland Detective Agency takes up the young witch's case. If Raf, Megan, and Raf's talking dog Bradley can handle space aliens, mummies, and ghosts, this case is child's play! But when a potion goes awry and a hooded stalker and a wannabe master criminal intervene, the case takes a wild turn into a full-blown catastrophe.
Will love-smitten supersleuth Megan and jet-pack inventor Raf be able to straighten out this mess in time? Or will Bradley's nose save the day once more?
