A highly decorated veteran agent recounts his incredible undercover career, and reveals the shocking links between narcotics trafficking and terrorism.

What exactly is 'undercover'? From a law-enforcement perspective, it's the art of skillfully eliciting incriminating statements.

Edward Follis mastered this dark art over the course of his distinguished 27 years with the US's Drug Enforcement Administration, where he bought bags of coke in a red Corvette, negotiated multi-million-dollar deals on board private jets, and developed covert relationships with men who were not only international drug-traffickers, but - in some cases - operatives for Al Qaeda, Hezbollah, and the Mexican federation of cartels.

Spanning five continents and filled with harrowing stories about the world's most ruthless drug lords and terrorist networks, Follis's memoir reads like a thriller. Yet every word is true, and every story is documented. The first and only insider's account of the confluence between narco-trafficking and terrorist organisations, The Dark Art is an electrifying page-turner.
