Before there were headlines, there was Leo Silva — working the shadows of Monterrey, running operations against the most dangerous cartel organizations in the Western Hemisphere. As Resident Agent in Charge of the DEA’s Monterrey Office, Silva spent decades at the sharp edge of America’s war on transnational crime, building cases against high-value targets that most people only read about in the news.
Now he’s telling the full story. Silva is the author of Reign of Terror and its Spanish-language edition El Reinado de Terror — a memoir that pulls no punches about what frontline law enforcement really looks like: the operations, the sacrifices, the bureaucracy, and the human cost on every side of the fight.
His writing draws on something no researcher or journalist can replicate — a career spent inside the story, where the stakes were measured in lives, not column inches.
