For a moment Daoud could not believe he had really heard it. The drug that he had brewed in his mind had taken control of his ears. Or else this was their way of tricking him into talking freely.

_But if they knew my Muslim name and that I speak Arabic, they would not waste time accusing me of being a Ghibellino._

"Wa aleikem salaam," he replied. The uprush of joy he felt at finding a friend here in this terrible cellar momentarily shattered the Face of Steel. What madness this was, that the friend should be the source of all his torment? He bit back hysterical laughter.

"Like you, I serve El Malik Dahir," Erculio said in Arabic. Hearing that t.i.tle, Daoud thought it even less likely that the little man was trying to trick him.

"I have been watching you since Lucera, My Lord," Erculio went on. "You have done well, even if it has been G.o.d's will that you should not succeed. You have been clever. But you should have taken the tawidh off before you surrendered. Do you think there are no Christians who can recognize Arabic numerals?"

Now Daoud was sure the little man was an ally of some sort.

In Arabic he said, "Does the scar on the back of my leg look fresh?"

"It has healed so completely that no one would believe you got it a few months ago. They know nothing of our Islamic medicine. You bear another wound, though, that would have much to say to the observant--your circ.u.mcision. That was why I had them put a loincloth on you and lay you facedown on this rack."

"Lucky for me you were here," Daoud said.

"Not luck," said Erculio. "El Malik deemed it wise that, should you be made a prisoner, one of his men ought to be among your captors."

_Even here, Baibars's hand reaches out to me_, thought Daoud, feeling a rush of grat.i.tude.

"Help me to escape," said Daoud. "The guards and the clerk are asleep."

Erculio brought his small hand downward in a gesture of flat rejection.

"There are a hundred men-at-arms on duty up above. The podesta himself will be down here in an hour. Why can you not make up a story that will satisfy him? Say you are a Ghibellino. That is what he believes, and since it is not true, it will not help him. In a thousand years he would never guess the truth."

"No. The only way I can protect those close to me is to admit nothing."

Erculio shook his head, and his black eyes were liquid with sadness.

"What a pity. Your case is hopeless, then. Ever since I saw you in Lucera I have felt sorry for you. How can El Malik expect one man to change the course of nations? You are like a man trying to hold apart two ships about to collide." He sighed. "I have done all I can for you.

I have hurt you as much as I can without doing you permanent injury--so far. There is only one other service I can perform for you."

"What is that?" said Daoud, though he felt sure he already knew the answer.

"You would not want to reveal under torture that you are an agent of the Sultan of El Kahira, and provoke the very crusade you were sent here to prevent. You would not want to give your friends away. If you break, I will see to it that you die before you might speak."

"I will not break," said Daoud. "And when it is all over, and d'Ucello has killed me, he will at last come to believe that I was telling the truth. Because he believes that no one can hold out against torture to the very end. But promise me one thing."

"Insh'Allah, anything."

"If you must cripple me, see that I do not leave this dungeon alive."

Understanding and respect glowed in the black eyes peering at Daoud over the edge of the rack. "As you wish, My Lord."

He knew he should be grateful that he had this man here to guarantee him a decent death. But a great sadness came over him at the thought that his life must end miserably in this dungeon. He had always hoped that he would meet his fate amid the glory of jihad, holy war.

_Well, this is jihad of a kind._

The respite was over. Erculio fell upon Daoud with renewed vigor, driving needles under his toenails and fingernails and beating him with a whip of knotted rawhide cords that tore open his back. Daoud felt the blood running down his sides and pooling underneath him. The little man took a red-hot poker and pressed it, hissing, against the scar made by the Tartar's arrow and Lorenzo's knife. That, Daoud realized, would make it impossible to tell what sort of wound it had been.

The pain seemed to be happening to someone miles away as Daoud converted it to ripples of light pa.s.sing through his body. He understood that Erculio was applying tortures whose effects could be seen. The podesta would be satisfied that Erculio had done his work well.

Daoud did his part too. The rest had restored his strength, and now Daoud screamed so loudly he woke the guards and the clerk. Erculio set the guards to work replacing the burned-down candles in the sconces around the dungeon. When Daoud turned his throbbing head to look at the candles, he saw hazy rings around them and rays radiating from them.

Sweat stung his eyes.

The thick wooden door of the cellar swung inward, and d'Ucello entered.

He walked over to where Daoud lay on the rack, and stood staring at him with his peculiar, glazed expression. D'Ucello's face was more sour than usual, and his eyelids were puffed. He looked just awakened from a sleep that had given him little refreshment. His mouth twitched under the thin mustache.

Daoud noticed that in one hand d'Ucello held a small silver flask with a narrow neck and a gla.s.s stopper. D'Ucello clenched his hand around it tightly, as if he feared to drop it.

"What has he said?" he demanded, turning to Erculio.

"Just much screaming, Signore." Erculio looked across the room at the bearded clerk, who nodded vigorously.

"You have not hurt him enough, then, Erculio," said the podesta. "He should be offering us _something_ by now. To withstand torture for so long almost smacks of sorcery."

"Perhaps he really has nothing to tell," Erculio ventured.

"Nonsense!" D'Ucello glared at the dwarf. "Even an innocent man would make the torture stop, if he had to lie to do it. And this man is not innocent."

_By that one remark Erculio risks much for me_, thought Daoud, praying the little man would not again endanger himself.

"Attenzione," said d'Ucello, coming close to Daoud's head and holding the flask so Daoud could see it. He withdrew the stopper, a long icicle of gla.s.s. He held the flask low over the rack table and tilted it momentarily. A few drops of dark brown liquid splashed onto the wood. At once d'Ucello righted and stopped the flask.

A white flash, bright as lightning, burst before Daoud's face, blinding him.

He jerked his head back and squeezed his eyes shut. He heard Erculio curse in Italian and the clerk and the guards cry out.

Smoke burned Daoud's nostrils and throat. As he coughed, he opened his eyes and saw a small fire burning its way into the wood a hand's breadth from his face. He felt a wave of heat. D'Ucello and his men watched in silence as the fire ate through the thick planking of the rack table.

Gradually the blaze lost its intensity as the liquid that started it was used up. It ended in a hole a man could pa.s.s his fist through, with glowing, smoking edges.

"What _is_ that?" said the clerk, tugging nervously at his brown beard.

"Witchcraft," said d'Ucello with a grim chuckle. The clerk and the guards stared at him. Erculio was expressionless.

In spite of Soma, in spite of his years of training, Daoud felt a scream of horror rising inside him at the thought of what d'Ucello was threatening.

"Not witchcraft, but just as evil," d'Ucello went on. "It is a weapon devised by the Byzantines."

"Ah!" said the clerk. "This must be that Greek Fire I have heard crusaders tell of. I always thought it another of their lies about the East."

"It is real," said d'Ucello. "Perhaps our guest, being from the East, has seen it before. The Turks stole the secret from the Byzantines and have been using it against the crusaders. It starts burning the moment it is exposed to air. It clings to whatever it touches, and its flames cannot be put out. Maligno."

The podesta turned to Daoud. "But in this case we will be using it for a good purpose. Messer David, do you love your organs of manhood?"

"What are you saying to me?" Daoud cried, determined that he would be David of Trebizond to the very end. His real terror now matched his pretended terror, but he managed to keep them two separate feelings. The scream trying to escape him battered itself like a trapped animal against the inner wall of the Face of Steel.
