ABOUT THE DIAMOND FILES

The Diamond Files is a high-stakes mystery thriller series following FBI Agent Nikki Diamond — a brilliant but relentless investigator drawn into cases where technology, conspiracy, psychology, and human darkness collide.

Set against a backdrop of cybercrime, experimental science, serial killers, government secrets, and emerging threats hiding in plain sight, the series blends cinematic suspense with procedural realism and fast-paced investigative storytelling. From impossible murders to dangerous new technologies capable of reshaping society itself, every case pushes Nikki further into a world where the truth is rarely what it seems.

What separates The Diamond Files from traditional detective fiction is its fusion of modern techno-thriller tension with deeply personal stakes. Nikki Diamond isn’t simply solving crimes — she’s navigating corruption, obsession, loss, and the psychological cost of constantly staring into the abyss.

Written by NYPD Counter-Terrorism Bureau officer Kevin P. Sullivan (and based on his late sister, Nicole) the series draws inspiration from real-world law enforcement experience while exploring the terrifying possibilities lurking just beyond the edge of modern reality.
