Our Kind of Traitor by John le Carré, Киев

Perry and Gail are idealistic and very much in love when they splurge on a tennis vacation at a posh beach resort in Antigua. But the charm begins to pall when a big-time Russian money launderer enlists their help to defect. In exchange for amnesty, Dima is ready to rat out his vory (Russian criminal brotherhood) compatriots and expose corruption throughout the so-called legitimate financial and political worlds. Soon, the guileless couple find themselves pawns in a deadly endgame whose outcome will be determined by the victor of the British Secret Service's ruthless internecine battles.
