Carolyn Keene 
Circus Act [EPUB ebook] 

Come one, come all, to the greatest show in town! Nancy, Bess, and George are attending Little Big Top circus day camp, and now they’re preparing for the big show. Bess will help Splatter the elephant make a painting, George will be an acrobat, and Nancy will perform with Celeste the Hopscotch Poodle. Then Celeste disappears while Nancy is taking care of her. Was Celeste dognapped by the Flying Tremendoes, the kid aerialists? Or by Orson Wong, who claimed the poodle made him sneeze? Or maybe by Katie Zaleski, who wanted Celeste for the TV program she’s taping in her basement? One thing’s for sure — there’s big, big trouble at Little Big Top!
