In 1795, a teenager discovered a strange circular depression in the ground on Oak Island, Nova Scotia, igniting rumors of buried treasure. Early excavators found a shaft with wooden platforms inside, but it began flooding, making further digging impossible. The so-called Money Pit has enthralled fortune seekers ever since, including a young Franklin D. Roosevelt and film star Errol Flynn. Most recently, Marty and Rick Lagina have taken on the quest, and in this companion to their History television series, Randall Sullivan ponders the many theories of what's hidden there, be it pirates' treasure, Marie Antoinette's lost jewels, the Holy Grail, or proof that Sir Francis Bacon was the true author of Shakespeare's plays.
