Adventurer and avid explorer Josh Gates takes viewers around the globe investigating the greatest legends in history. And now, a case Josh has been chasing for years has been solved, right in his hometown of Boston, Massachusetts. After two adventures chasing buried treasures from Byron Preiss’ 1982 treasure hunt, The Secret, Josh meets up with Boston local, Jason Krupat and the two embark on a legendary journey to uncover the famed treasure in an all-new episode of EXPEDITION UNKNOWN, airing Wednesday, October 30th at 9PM ET/PT on Discovery Channel.

The objective in Preiss’ famed treasure hunt, The Secret, is to match one of the twelve paintings to one of the twelve poetic verses, solve the resulting riddle and dig for the key. Prior to publishing, Byron Preiss secretly traveled to twelve locations in the United States and buried a dozen ceramic casques that once uncovered contained a key that could be exchanged for a beautiful gemstone. Since 1982, only two of the twelve casques have been discovered - until now.

Inspired by past episodes of EXPEDITION UNKNOWN, Jason Krupat, a game designer by day, set out to solve one of Preiss’ puzzles and contacted Josh after successfully piecing the riddle together, but when the two met to dig up the physical casque and key, they faced thrilling challenges and surprise findings as they unraveled Preiss’ mystery. Josh and Jason will take viewers around Boston on an epic adventure tracing clues and following the step-by-step process of what went into solving the decades old mystery. This historical event closes the book on one chapter of The Secret and brings closure to Josh's years-long search for the treasures.
