Robin Monarch is the CIA's top field asset. He is also an expert thief. Son of an American cat burglar and an Argentinian con artist, orphaned at thirteen, his is a character forged and hardened amid the ruthless slum gangs of Buenos Aires.

During a field operation in Istanbul, Monarch uncovers evidence of corruption stemming back to the very top of the CIA and Congress. This discovery – project Green Fields – is enough to make him rethink his loyalties, and go rogue.

An international crisis is sparked, with Monarch at its centre. Washington politicians, European criminals and Middle Eastern arms dealers are all hunting him – to force him to share his information, or to ensure his silence. Or, Monarch fears, both.

To survive, Monarch will have to rely on a code he learned as a starving boy, orphaned and abandoned in the slums of South America. This code is the eighteen-rule-strong La Fraternidad des Ladrones, the Brotherhood of Thieves.
