The Mysterious Disappearance of Leon (I Mean Noel)

From the Newbery Award-winning author of THE WESTING GAME, more clever riddles and wordplay, clues to be found, and mysteries to be solved!

Glub! Blub!
Mrs. Caroline "Little Dumpling" Carillon isn't quite sure what to expect when she sets off to meet her husband, Leon.  After all, she hasn't seen him since their wedding when she was five and he was seven. But their reunion is cut short when a storm knocks him off their boat, and he disappears completely, leaving only one very waterlogged clue (Glub! Blub!). Will Dumpling be able to find Leon (or is it Noel) again? And just what is a glub blub?
