When Frank and Joe attend a magic seminar, coins and rabbits aren't the only things vanishing into thin air. Valuable items start disappearing from the hotel safes--and the teen sleuths are in the middle of a magical mystery. If they don't crack this case soon, the Hardy Boys may vanish, too--permanently!
