Aunt Jen, the official White House hostess, is being thrown a surprise party with a Wizard of Oz theme. A dog that looks just like Toto will be there — and so will the famous ruby slippers that Judy Garland wore in the movie. But when the box arrives from the Smithsonian Museum, the slippers aren’t in it! Never fear, First Kids Cammie and Tessa are on the case. White House dog Hooligan finds one slipper, but no one know where or how. A surprising revelation reveals the thief’s identity. Filled with humor and White House inside information, this third First Kids Mystery is exciting from start to finish.
