by Dennis T. Cosgrove (Author)

A woman walks into an FBI field office with one demand: a Russian-speaking agent. What follows detonates a chain reaction of secrets, danger, and a conspiracy so strange it defies belief.

Inspired by true events from the author's career as a Special Agent, The Diamond Game drops you into a world of missing tech moguls, cults, kidnapping, and looted Cold War treasures-along a trail of betrayal, deadly seduction, and high-stakes deception.

This is the FBI from the inside: raw, unfiltered, and stranger than fiction.

Inside the Bureau, truth can be weaponized. Loyalty can be fatal. And what you believe can get you killed.

The Diamond Game isn't just a thriller. It's the case file they'd never let you read-until now.
