Secrets of the desert - Christian Jacq

Having discovered a monstrous conspirary to overthrow the pharaoh, Ramses II, Judge Pazair has been deported for a crime he did not commit and sentenced to die in a prison camp. But the conspirators have reckoned without the love of Neferet, the young woman doctor Pazair has just married, and the courage of Suti, his friend with the hot head and the generous heart.
Together, Neferet and Suti attempt to rescue Pazair, so that he can resume his investigation. For there are many questions yet to be answered. Who murdered the veteran guards of the Great Spinx? Who violated the Great Pyramid and stole the Testament of the Gods, which guarantees Pharaoh's legitimacy? Who killed Pazair's spiritual master?
