The Diamond Game

By: Dennis T. Cosgrove

Narrated by: Dennis T. Cosgrove

Kidnapping. Corruption. A shattered empire’s stolen treasures.

When a mysterious young woman walks into the FBI office asking for a Russian-speaking agent, Special Agent Cosgrove is pulled into a high-stakes game with no rules—and no clear way out.

Drawn from real-life cases of the author, a former FBI Special Agent, The Diamond Game pulls back the curtain on a hidden world of power, betrayal, and survival.

Names and events have been changed to protect identities—but the danger, the stakes, and the emotional truth remain.

This isn’t just what could happen. It’s what did.

Perfect for fans of Daniel Silva, Karin Slaughter, and anyone who craves thrillers grounded in truth.

Impressive first book

I am very impressed with this author‘s first book. When you realize that the story is semi-fiction it is scary to think of his real life profession. I like the characters, the flow of the story, and the thrill and excitement of this one case involving diamond smuggling from Russia. The fact that this FBI agent dealt with the scariest Russian criminals is riveting. Dennis T. Cosgrove must have more stories up his sleeve. What will you bring us next.
