The Secret is a treasure hunt created by Byron Preiss. The hunt involves a search for twelve treasure boxes, the clues to which were provided in a book written by Preiss in 1982, also called The Secret. These boxes were buried at secret locations in cities across the United States and Canada that symbolically represent events and peoples that played significant roles in North American history. Anyone who uncovered one of the treasure boxes was entitled to exchange it with Preiss for a precious gem. Preiss died in a car accident in 2005. His estate assumed the responsibility of honoring the terms of the treasure hunt. As of 2024, only three of the twelve boxes have been found. Preiss kept no record of the treasure boxes' exact locations before his death, leaving it a possibility that the remaining boxes may never be recovered. Source: Wikipedia (en)
