Martin Suarez, a legend within the FBI who specialized in Colombian drug cartels, holds the record for the longest time spent continuously undercover. As his alter ego Manny, Martin followed the unspoken rules of the cartels: He knew the right lingo to use, the right whiskey to drink, the right watch to wear, the wrong questions to ask. He smuggled over $1 billion worth of cocaine into the United States for the Medellín Cartel and, as his cover deepened, he graduated to become a high-level money launderer for the North Coast Cartel. He helped wash tens of millions of dollars worth of drug money, ensnaring himself in a high-stakes game of cat and mouse while simultaneously exposing the Black Market Peso Exchange, the most insidious money laundering apparatus in the world that involved billionaire bankers, blue-chip American corporations, and even the President of Colombia himself.
