1934. A private detective, Miranda Green leaves England for Egypt. She must investigate a murder perpetrated in a supposedly inviolable place: the British Embassy in Cairo, where a top secret document was stolen the same night. All those present in this closed place are suspected: the American photographer, the English singer, the Egyptian security guard, the French businessman, the Indonesian gardener and - why not? — the Ambassador himself. But who would have expected that a small group of Nazis would be behind a plot, risking to jeopardize both Buckingham Palace and the peace of the world?
