File No: ANT-001 // Clearance: Top Secret
Espionage & Cyber Thrillers
Agent Profile
Stephen Antcliff writes the kind of thrillers that pull you into the shadow world of espionage and cyber warfare — where the line between ally and enemy is drawn in code, and trust is the most dangerous currency of all.
His Callum Heath series follows a Cambridge University PhD student from the safety of academia into the world of MI5, navigating the murky intersection of state secrets, digital warfare, and personal loyalties. Each book peels back another layer of a world where nothing is quite what it seems.
