It's World War I. Britain's shadow government, headed by its Agent and Consul General under the nominal authority of Egypt's hereditary ruler the Khedive, has ruled Egypt since 1881. The head of the Secret Police is the Mamur Zapt, an office currently held by a Welshman, Captain Gareth Cadwallader Owen. And as the clouds of the war further darken Egypt's sun-lit skies, he has his hands full. On the professional front, there's all that commotion that started in Cairo's Camel Market. On the personal side, Owen has married his longtime lover, the lovely Pasha's daughter, Zeinab. Their union comes with serious consequences for both of them and is riddled with political and social pitfalls. Neither can be fully accepted by the other's culture and community. Against this, the perils of the Great War pale.
