On Australia Day in 1966, three children were allowed to go unsupervised to a public beach to escape the summer heat in Adelaide, Australia. This was an accepted practice by most at the time as Australia was considered a safe country. When the children didn't return from the beach, Australia's largest crime mystery began and almost 60 years later there is still no answer to what happened to Jane, Arnna, and Grant that fateful day. Listen along as we analyze this historic case in TBCI's first international episode. Music by Gioele Fazzeri from Pixabay.
