Thebes Of The Hundred Gates: Robert Silverberg

Two time-travellers from the 27th century go missing in Ancient Egypt. Edward Davis, a promising rookie in the Time Service is sent back to find them...back much further than he has ever been before. Reeling from the time-jump, he arrives in Thebes only to find his survival training is no protection against the intoxicating magic of Egypt: Pyramids and obelisks; snakes with legs; winking sphinxes; birds with the heads of women and women with the heads of birds; forests of huge stone columns; lapis lazuli and gold and a plump Pharaoh on his throne. Davis has thirty days in which to get a grip and find the missing time travellers. Instead, he's taken in by a temple priestess, befriended by a beautiful slave girl and tricked into crossing the Nile to to the City of the Dead. As the scheduled hour of his rendezvous with the time field approaches, Davis is faced with the truth behind the fate of his former colleagues and the prospect of sharing that fate.
