Journalist Misha Glenny spent several years in a courageous investigation of organized crime networks worldwide, which have grown to an estimated 15% of the global economy. From the Russian mafia, to giant drug cartels, his sources include not just intelligence and law enforcement officials but criminal insiders.

Journalist Misha Glenny leaves no stone unturned (and no failed state unexamined) in his excavation of criminal globalization.

In minute detail, Misha Glenny's 2008 book McMafia illuminates the byzantine outlines of global organized crime. Whether it's pot smugglers in British Columbia, oil/weapons/people traffickers in Eastern Europe, Japanese yakuza or Nigerian scammers, to research this magisterial work Glenny penetrated the convoluted, globalized and franchised modern underworld -- often at considerable personal risk.

The book that resulted is an exhaustive look at an unseen industry that Glenny believes may account for 15% of the world's GDP.

Legal society ignores this world at its peril, but Glenny suggests that conventional law enforcement might not be able to combat a problem whose roots lie in global instability.

While covering the Central Europe beat for the Guardian and the BBC, Glenny wrote several acclaimed books on the fall of Yugoslavia and the rise of the Balkan nations. He's currently researching a new book on cybercrime.
