It is not every day that one of the world's great mysteries gets solved. For 70 years, the identity of the Somerton Man, whose body was found on a beach outside of Adelaide, Australia, on December 1, 1948, has been frustratingly elusive. With no identification on him and many strange circumstances about his personal effects, speculation about his identity has run rampant. A spy? A time traveller? An alien? We know now with a high degree of certainty exactly who he was and what he was doing on that beach. We are joined by the University of Calgary's Dr. Lars Petersen to share how the mystery man's identity was finally determined and what we know about him and his life.

New to the case? We recommend starting with Episode 141 – Solving the Somerton Man Mystery first, before listening to this episode.
