Viktor Bout was the world's foremost arms dealer. From his hideout in Moscow, he masterminded the sale of weapons to dictators, rebels, despots, and terror groups worldwide--supplying anything from AK-47s to state-of-the-art helicopter gunships and anti-aircraft missiles. Known as the Merchant of Death, he was hunted by MI6, INTERPOL, the CIA, the NSA, and more. But the former KGB officer was shielded by a Russian state that partnered in his dark dealings.

Evading capture for years, Bout appeared utterly invulnerable. Then elite forces veteran Mike Snow, AKA The Bear, stepped forward. Snow had gotten to know Bout while working as a bush pilot in war-torn Africa. When the Drug Enforcement Agency approached Snow through a secretive, shadow network, they had one question for him: could he ensnare the Merchant of Death?

This is the real-life tale of Operation Relentless, the classified mission masterminded by Snow and a team of DEA operatives. Based on first-hand testimonies, it is the thrilling tale of a manhunt that ranges from the jungles of Colombia to the streets of Moscow, from horrific bloodshed and tyranny in Afghanistan to a snatch operation like no other.
