In 523 BC, the Persian emperor Cambyses dispatched an army across Egypt's western desert to destroy the oracle of Amun at Siwa. Legend has it that somewhere in the middle of the Great Sand Sea his army was overwhelmed by a sandstorm and destroyed. Fifty thousand men were lost. Two and a half thousand years later a mutilated corpse is washed up on the banks of the Nile at Luxor, an antiques dealer is savagely murdered in Cairo, and an eminent British archaeologist is found dead at the ancient necropolis of Saqqara. At first, the incidents appear unconnected. Inspector Yusuf Khalifa of the Luxor police is suspicious, however. And so too is the archaeologist's daughter, Tara Mullray. As each seeks to uncover the truth, they find themselves thrown together in a desperate race for survival - one that forces them to confront not only present-day adversaries but also ghosts from their own pasts. From a mysterious fragment of ancient hieroglyphic text to rumours of a fabulous lost tomb in the Theban Hills, from the shimmering waters of the Nile to the dusty backstreets of Cairo, Khalifa and Mullray are drawn ever deeper into a labyrinth of violence, intrigue and betrayal. It is a path that will eventually lead them into the forbidding, barren heart of the western desert, and the answer to one of the greatest mysteries of the ancient world.
