Person
Dennis T. Cosgrove spent decades chasing bad guys as an FBI Special Agent and later advising governments on international security?then he started chasing stories. His debut novel, The Diamond Game, blends fact-based fiction with sharp storytelling inspired by years of global work in law enforcement, including leading border security efforts across Europe and Central Asia.
When he's not writing thrillers, Dennis might be on a rugby pitch (playing touch these days), doing yoga, or swimming in open water. He lives in Florida with his wife, two grown kids (somewhere out there), and a head full of plots. His next novel, Nadezhda Dies Last, is coming soon.
