The Bedouin were keeping me alive for a reason. I was useful, you see. Someone there had assumed I had a skill when my plane crashed in the desert. I am a man who can recognize an unnamed town by its skeletal shape on a map. I have always had information like a sea in me. I am a person who if left alone in someone’s home walks to the bookcase, pulls down a volume and inhales it. So history enters us. I knew maps of the sea floor, maps that depict weaknesses in the shield of the earth, charts painted on skin that contain the various routes of the Crusades.
