In the heart of the big city live two ace detectives—Bunny and Jack are their names, cracking cases wide open is their game. In their third case, The Case of the Puzzling Possum, a trombone disappears from Mr. Riley’s music store. The next day, it’s back. Then it’s gone again. Who could be taking it—and why? Beginning readers and fledgling detectives alike will love these fun, fast-talking mysteries brought to life by another unsurpassed duo—Newbery medalist Cynthia Rylant and illustrator G. Brian Karas.
