The Magician's Secret: Nancy Drew Diaries, Book 8

Dear Diary...

"Magic is a mystery that doesn't need solving." That's what illusionist Drake Lonestar told me when I saw him perform. I was skeptical that the famous magician could really make the River Heights courthouse disappear, but I was wrong.
 It turns out that the courthouse wasn't the only thing that vanished. So did important evidence relating to a jewel heist - and all signs point to Lonestar as the thief! Now the magician himself has disappeared into thin air - and all of River Heights is looking at me to track him down. I just hope I can do it soon, because I have a feeling Lonestar has one last trick up his sleeve....
