But when a real mystery unfolds at school, Houdini realizes that playing cards are not the only things vanishing from the classroom. When the beloved classroom pet suddenly goes missing, the whole school is in an uproar. Has Houdini's talent for making things disappear somehow affected the class animal, or is there a sneakier culprit on the loose? Teaming up with his smart and observant cousin, Janet Perry, Houdini must put his magic skills aside and use his best detective work to crack the case. Together, this super-sleuth duo will search for clues, interview their classmates, and try to bring their furry friend back safely. You will even learn how to perform Houdini's famous Wacky Jacks card trick yourself as you follow along with this fun, fast-paced school adventure.
