CIA operatives Sia and Max enter Russia to recruit Vladimir Putin's moneyman. Sia works for a London firm that conceals the wealth of the super-rich. Max's family business in Mexico-a CIA front since the 1960s-is a farm that breeds high-end racehorses. They pose as a couple, and their targets are Vadim, Putin's private banker, and his wife, Anna, who is both a banker and an intelligence officer. As they descend further into a Russian world dripping with luxury and rife with gangland violence, Sia and Max's hope may be Anna, who is playing a game of her own. Careening between the horse ranch and the dark opulence of Saint Petersburg, Moscow X is both a gripping thriller of modern espionage and a daring work of political commentary on the conflict between Washington and Moscow.
