Summoned late at night to the Bureau, Quiller attends a secret conference with the foreign secretary and a surprise defector: the Chinese ambassador to Britain. Minutes later, shots ring out and the ambassador's body is flung out onto the sidewalk of a deserted London street, riddled with bullets. Searching for clues, Quiller flies to Calcutta to meet Sojourner, a key ally in the plan to bring democracy to China. But Sojourner is killed-thus, two men, both dedicated to bringing freedom to their country, are dead. No wonder Quiller is skeptical about his next mission: to smuggle a Chinese dissident into Tibet.
