Urban's eyes grew wide and he leaned forward. "And I will preach yet another crusade, Simon. Against Manfred the Antichrist. That is why I would have sent for you if you had not come here. You must make the journey to King Louis and tell him that this crusade that I will preach is the most important war of his lifetime. He must come to my aid. I will make his brother Charles king of southern Italy and Sicily. I will write the letter to King Louis, and you will carry it to him." _Now I must make my effort._ "He will heed your appeal if you give him what he wants, Your Holiness. Write that letter. But in it give your permission for King Louis to ally himself with the Tartars and begin preparations for a new crusade." Urban looked slyly up at Simon. "Surely you suspect that it was I who persuaded Fra Tomasso d'Aquino to change his colors where the Tartars are concerned. I saw to it that the possibility of an alliance was kept alive, so that I might have something Louis and I could haggle over. Louis is the most stubborn man in the world. If I simply give him whatever he wants, there is no guarantee that he will give me what I want." Simon took a deep breath. What he was about to say might offend the pope deeply. "Your Holiness, you have said it yourself. There is no more time for haggling. You must make your best offer and hope it is enough." The pope shut his eyes and slumped in his chair. Simon's heart went cold, thinking for a moment that the old man had suffered a seizure. But then Urban said very softly, "Help me to turn my chair around." Now Simon's heart beat faster as he moved the pope's chair so that it faced his desk. Urban took a gleaming blank sheet of parchment from the pile on his desk, dipped a quill, shook it, and began to write. Simon stood by the wall, his heart pounding with exhilaration. Could it actually be that his words had moved the pope himself? It seemed impossible, as if he had stood in the path of a mighty river and diverted its course. "The Tartars," the old man said with a sigh sometime later, when he had covered two sheets of parchment. "I hope I am not making a terrible mistake. I still think Fra Tomasso was right in what he first said about them." He dropped wax at the bottom of the letter, stamped it with his ring, and blew on the wax to cool it. Then he folded the parchment and sealed it again. "Ride to King Louis as quickly as possible." Urban turned, again half rising from his chair, and handed Simon the letter. "Shall I carry the king's answer to Perugia, Holy Father?"
