The Lion of Cairo : On the banks of the ageless Nile, from a palace of gold and lapis lazuli, the young Caliph Rashid al-Hasan rules as a figurehead over a crumbling empire. Cairo is awash in deception. In the shadow of the Gray Mosque, generals and emirs jockey for position under the scheming eyes of the powerful grand vizier. In the crowded souks and narrow alleys, warring factions employ murder and terror to silence their opponents. Egypt bleeds. And the scent draws her enemies in like sharks: the swaggering Kurd, Shirkuh, who serves the pious Sultan of Damascus and Amalric, the Christian king of Jerusalem whose greed is insatiable and whose knights are hungry for battle. And yet, all is not lost. There is an old man who lives on a remote mountainside in a distant land. He holds the power of life and death over the warring factions of the Muslim world - and decides to come to the Caliph's aid. He sends his greatest weapon into Egypt. He sends a single man. An Assassin. The one they call the Emir of the Knife. . . .
