Two young lovers treat themselves to a once-in-a-lifetime holiday on the Caribbean island of Antigua. He's an austere tutor at Oxford. She's a sparky rising London barrister. Their native Britain is floundering in debt. On the second day of their holiday they encounter a rich, charismatic fifty-something Russian millionaire called Dima who owns a peninsula, wears a diamond encrusted Rolex watch, has a tattoo on the knuckle of his right thumb and wants a game of tennis. What else Dima wants is the engine that drives John le Carré's majestic, thrilling, tragic, funny and utterly engrossing new novel of greed and corruption, from the arctic hells of the gulag archipelago to a billionaire's yacht anchored off the Adriatic coast; to the Men's Final of the French Open tennis championships at the Roland Garros stadium; to two murky Swiss bankers dubbed Peter and the Wolf; and finally and fatally to a Swiss alpine resort nestling in the shadow of the north face of the Eiger and the story's terrifying end.
