Undeterred by world war and enemy submarines, Amelia Peabody -- Grandmaster Elizabeth Peter's indomitable archaeologist-sleuth -- once again sets sail for Egypt, where ghosts of an ancient past and spectors of a present-day evil hover silently over an inscrutable land. With son Ramses, his wife, Nefret, and a few unwelcome additions in tow, the elder Peabody-Emersons embark on a dangerous sea voyage to Alexandria, ultimately ending up in Cairo for their annual excavations. But in this autumn of 1915 the exotic, alluring city is not what it used to be. Cairo has been transformed into an armed camp teeming with the enemy agents, and shockingly bold tomb robbers are brazenly desecratingg the ancient sites. Yet there is an even darker danger in store for the Emersons. Can it be that one of Amelia's oldest and most dangerous adversaries will intervene to alter the family's destiny? Tantalizing clues suggest that this may be so and point toward an archaeological discovery of unparalleled importance -- and the resurrection of a voice that has been silent for millenia.
