The banks of the Nile held many mysteries for Christina. There were the secrets of a tomb her father had discovered, and the strange young man she found lying half-dead on the steps one fateful day. 

Taking pity on him, Christina secretly nursed him back to health, only to discover that he was not a native, but a fellow Englishman. A most handsome Englishman.

He called himself Sidi. But who was he, really? No one knew.

She began to dread the moment when she and her father would have to return home. She knew she would miss Sidi very much, and that was a luxury she would not allow herself. And yet...

When they met again in England, it was not as Christina had dreamed it would be. Sidi had become a different person - someone who claimed he had never seen her before in her life!
