For three decades, a phantom haunted Wichita, Kansas, a killer who gave himself the chilling moniker BTK. He bound, tortured, and killed his victims, then melted back into the fabric of the community, leaving behind only taunting letters and a city paralyzed by fear. When the letters suddenly stopped, authorities feared he was gone forever—until a final, arrogant communication years later provided the one clue they needed. This is the story of a monster who hid in plain sight, and how the very pride that fueled his crimes would ultimately become the instrument of his capture.
