A major magic trick leads to missing murder evidence in this eighth book of the Nancy Drew Diaries, a fresh approach to a classic series. When she attends a performance by master illusionist Drake Lonestar, Nancy is skeptical. Lonestar is known for his razzle-dazzle wizardry, but can the magician really make the River Heights library disappear? As it turns out, he can, but that's not the only thing that goes missing. Key evidence to an upcoming murder trial disappears in the midst of the trick. And one of the trial attorneys just happens to be Nancy's father, Carson Drew, assisted by her boyfriend, Ned Nickerson. Nancy, Bess, and George are quick to jump on the case, but not quite quick enough: Lonestar has vanished, too, and not even his closest friends know his whereabouts. Magic is its own kind of mystery, but is this one Nancy can handle?
