Cairo, 1869. When a bomb goes off at the Khedivial Opera House celebrating the opening of the new Suez Canal, visiting Assassin Pierrette Arnaud investigates, only to uncover a plot to eradicate free will... To her surprise, her old friend and teacher Simeon Price arrives in Egypt on the same trail, seven years after they allied to stop the Templars in London. But there's no time to reminisce as the Templars maneuver Europe and Africa like pieces on a chessboard, wreaking havoc on a global scale. As Simeon and Pierrette race to stop further attacks, they unearth plans suggesting a mysterious tower is the key to the ultimate Templar takeover... and with the puzzling Engine of History in their grasp, the Assassins might be outmatched at last.
