While spending Thanksgiving in Plymouth, Massachusetts, the kids learn about a sapphire necklace that went missing on the real "Mayflower." Could the 400-year-old treasure be hidden somewhere nearby? This exciting mystery features a 26-letter message hidden in the art. Illustrations. With the publication of The Zombie Zone in April 2005, the A to Z Mysteries series was complete. But, A to Z fans, no need to fear; the A to Z Mysteries Super Editions are here! The fans wanted more, and they're getting it — more adventure, more illustrations, more Dink, Josh, and Ruth Rose — all in a book nearly double the length of standard A to Z Mysteries. The alphabet may be finished, but A to Z fun keeps on coming!
