Deciphering Evil: Zodiac and the Science...

About this episode

American history — a killer who terrorized California, taunted the media, and challenged the world to crack his ciphers.

Each episode unravels a different layer of the Zodiac mystery: from his first brutal attack to the haunting letters that confounded experts for decades. Through forensic psychology, criminal profiling, behavioral science, and investigative storytelling, we explore the twisted intelligence behind his crimes and the enduring obsession to unmask him.

You’ll hear chilling reenactments, interviews with experts, and deep psychological analysis revealing not just how the Zodiac operated — but why. Was he a mastermind or a madman? A lone predator or part of something darker?

Subscribe now and join the investigation. Because some codes were never meant to be broken… and some killers never meant to be caught.
