‘Meth, murder and pirates: the coder who became a crime boss. A world that lurks just outside of our everyday perception, in the dark corners of the internet we never visit’ – Wired

The Mastermind tells the incredible true story of Paul Le Roux, the frighteningly powerful creator of a twenty-first century cartel, and the decade-long global manhunt that finally brought his empire to its knees.

Le Roux’s business evolved from an online prescription drug network into a sprawling multinational conglomerate engaged in almost every conceivable aspect of criminal mayhem. All tied together with encryption programs so advanced that government agencies were unable to break them.

Tracing Le Roux’s vast wealth and his shadowy henchmen around the world, award-winning journalist Evan Ratliff spent four years piecing together this intricate network. His investigation reveals a dark parable of ambition and greed, and exposes a new age of crime in which a reclusive entrepreneur can build an empire in the shadows of our networked world.
