A Mail Order Mystery is an immersive, interactive story for kids told through a series of clues and documents that come in the mail. That doesn't even begin to cover the magic of the whole experience though. Once a week, a mysterious envelope or package arrives in the mail addressed directly to your child. Each mailing contains an assortment of personalized letters, secret missions, and cryptic messages, along with mysterious objects, puzzles to solve, codes to crack, and clues of all kinds.
