Who is Trixie Belden? Trixie first appeared over fifty years ago in The Secret of the Mansion, which was followed by thirty-eight other adventures as generation after generation of readers grew up with mystery-loving Trixie and her friends. Now, after fifteen years, Trixie is back to make fans of a new generation! While looking for antiques in Honey's attic, Trixie stumbles across an old key. It has a bizarre tag hanging from it with a message written in a code of funny-looking little men.
