Meet & Greet with Dennis Cosgrove- Local Author Spotlight

Join Books on Third for an author event featuring Dennis T. Cosgrove, former FBI Special Agent and author of the thriller The Diamond Game.

The Diamond Game, the first book in the Directive Seven FBI thriller series, opens when a woman walks into an FBI field office with one chilling demand: she will speak only to a Russian-speaking agent. What follows is a cascade of secrets, danger, and a conspiracy so strange it defies belief.

Inspired by true events from Cosgrove’s decades-long career with the FBI, the novel plunges readers into a shadowy world of missing tech moguls, cults, kidnappings, and looted Cold War treasures—woven together with betrayal, deadly seduction, and high-stakes deception. This is the FBI from the inside: raw, unfiltered, and stranger than fiction.

During his career, Dennis T. Cosgrove pursued criminals and advised governments on complex security issues across the U.S., Europe, Russia, Central Asia, and the Balkans. His firsthand experience gives his writing a rare authenticity that sets his thrillers apart.

Cosgrove will discuss The Diamond Game, his writing process, and how real cases inspired the Directive Seven series. Copies of The Diamond Game and Nadezhda Dies Last, the second book in the series, will be available for purchase, followed by a book signing and Q&A.

This event is perfect for fans of intelligent thrillers, espionage, and true-to-life crime fiction.
