Echoes of the Unknown

In today's episode, we're traveling back to the summer of 1975, when former Teamsters boss Jimmy Hoffa walked into the parking lot of a suburban Detroit restaurant to attend a meeting — and was NEVER seen again. At the time, he was still a powerful and determined force within the labor movement. Over half a century later, his baffling disappearance remains one of the most enduring unsolved mysteries in American history.

In today's episode, we're heading to Somerton Beach in Adelaide, Australia, where a man was found dead in 1948 — with no ID, and labels cut from his clothes. Police found a small scrap of paper with the words “Tamám Shud" in a hidden pocket of his clothing. It was torn from a copy of the Persian poetry book Rubáiyát of Omar Khayyám. Although the phrase means "it is finished," for investigators, the mystery was just beginning.

In today's episode, we’re traveling back to the spring of 2001, when the disappearance of a young federal intern named Chandra Levy in Washington, D.C., became a national obsession. It was a story that unfolded in layers — part missing person investigation, part political scandal, and ultimately, an unsolved homicide that still raises the same haunting questions it did more than two decades ago.

In today's episode, we’re opening a book that no one has ever been able to read. It’s not a legend. It’s not a lost text whispered about in the shadows. It’s real. It exists. You can see its pages yourself. For over 600 years, it has held onto its secrets. The medieval Voynich Manuscript is written in an unknown script, illustrated with impossible plants and strange celestial charts, studied by generations of experts — and still unreadable.

In today's episode, we’re traveling back to the summer of 1992, to a quiet neighborhood in Springfield, Missouri. One weekend night, three women vanished from the same home — a mother, her teenage daughter, and her daughter's friend. They left behind cars in the driveway, purses on the counter, and a baffling mystery that has never let go — even with the passage of more than three decades.
