The Eleventh Hour (Picture Puffin) by Graeme Base

When Horace the elephant turns eleven, he celebrates in style by inviting his exotic friends to a splendid costume party. But a mystery is afoot, for in the midst of the games, music, and revelry, someone has eaten the birthday feast. The rhyming text and lavish, detailed illustrations each provide clues, and it's up to the reader to piece them together and decide whodunit! "The fun of poring over the pictures is matched by the enjoyment derived from the textwitty, ingenious verses." -- Publishers Weekly Graeme Base is the author of many award-winning books for children, including Animalia (Puffin), The Sign of the Seahorse , and most recently, The Discovery of Dragons .
