In today's episode, we're traveling to Liverpool, England in 1931, where a quiet insurance agent named William Wallace returned home to find his wife brutally murdered.

In today's episode, we're traveling back to 1966, to a quiet hillside in Brazil, where two electronics technicians were found dead under strange circumstances. They had carried a bottle of water, a notebook, and a pair of masks made from sheets of lead. A cryptic note revealed they were supposed to swallow capsules, put on the masks, and wait. Decades later, investigators still don't know how they died ... or what they were waiting for.

In today's episode, we’re traveling back to 1964, when a quiet suburban neighborhood in Ohio was shattered by a brutal crime.

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.
