SIX MURDERS. THIRTY DAYS. A SYSTEM THAT FAILED EVERYONE.

In the winter of 1978, the quiet streets of Arden-Arcade, California, became the hunting ground for one of the most violent disorganised killers in American history. Richard Trenton Chase did not hide in the shadows; he walked into unlocked homes in broad daylight, driven by severe somatic delusions.

But the tragedy of the Sacramento murders began long before the first shot was fired. It began in overcrowded psychiatric wards, in paper-based firearm registries that failed to cross-reference mental health holds, and in an administrative system that turned a blind eye to a man unravelling in plain sight.

Painstakingly researched and written with unflinching clinical accuracy, The Unlocked Door takes you beyond the sensationalised headlines. It delivers the complete story of the victims, the groundbreaking FBI profile that caught a monster, and the enduring legacy of a case that changed criminalistics forever.
