"You're good men. We mean to pray, but sometimes we forget." His tribesmen cackled at his wit._ I didn't pay any attention to that. "We'll need water for. tomorrow's journey, O Shaykh," I said. I suppose I could've phrased that more politely.

Muhammad thought about it for a moment. He couldn't very well refuse, but he wasn't happy about part-ing with any of his own supply. He leaned over and mut-tered something to one of the others. The second Bedu got up and fetched a goatskin bag of water and brought it to me. "Here, my brother," he said with a blank expres-sion. "May it be pleasant to you."

"We're obliged," I said. "We'll just fill our canteens, and return the rest of the water to you."

The man nodded, then reached out and touched one of my corymbic implants. "My cousin wants to know what these are," he said.

I shrugged. "Tell your cousin that I like to listen to music on the radio."

"Ah," said the Bayt Tahiti. I don't know if he believed me. He came with me while I filled my canteen and Papa's.

Then the Bedu took the goatskin bag and returned to his friends.

"The sons of bitches didn't invite us to join them by the fire," I said, sitting down on the sand beside Papa.He only turned one hand over. "It means nothing, my nephew," he said. "Now, I must sleep. It would be well if you remained awake and watchful."

"Of course, O Shaykh." Papa made himself as com-fortable as he could on the hard-packed sand of the desert floor. I sat for a little while longer, lost in thought. I re-membered what Papa had said about revenge, and from the pocket of my gallebeya I took the paper the qadi had given me. It was a copy of the charges against Friedlander Bey and rne, the verdict, and the order for our deportation. It was signed by Dr. Sadiq Abd ar-Razzaq, imam of the Shimaal Mosque and adviser to the amir on the inter-pretation of shari'a, or religious law. I was happy to see that Shaykh Mahali had apparently played no part in our kidnapping.

Finally, I decided to lie down and pretend to be asleep, because I realized that the Bayt Tabiti were watching me, and that they wouldn't retire for the night until I did. I stretched out not far from Friedlander Bey, but I didn't close my eyes. I was sleepy, but I didn't dare drift off. If I did, I might never awaken again.

I could see the top of a gracefully curved dune about a hundred yards away. This particular sand hill must have been two hundred feet high, and the wind had blown it into a delicate, sinuous fold. I thought I could see a stately cedar tree growing from the very crest of the dune. I knew the mirage was a product of my fatigue, or perhaps I was already dreaming.

I wondered how the cedar tree could live in this wa-terless place, and I told myself that the only answer was that someone must be cultivating it. Someone had planned for that cedar to be there, and had worked very hard to make it grow.

I opened my eyes and realized that there was no cedar tree on that dune. Maybe it had been a vision from Allah.

Maybe God was telling me that I had to make plans, and work very hard and persevere. There was no time now for rest.

I lifted my head a little, and saw that the Bayt Tabiti had thrown themselves on the ground near their fire, which had died down to pale, weakly glowing embers. One of the Bedu had been ordered to keep watch, but he sat against a wall of sand with his head thrown back and his mouth open. His rifle lay discarded beside him on the ground. I believed all six of them were sound asleep, but I did not stir. I did nothing for another hour but stare at the seconds as they flicked by in the window of my watch. When I was certain that all the Bayt Tabiti were in deep slumber, I sat up quietly and touched Friedlander Bey on the shoulder. He came awake quickly. Neither of us said a word. We picked up our canteens and rose as silently as we could. I agonized for a few moments about trying to steal food and rifles, but at last I knew it would be suicidal to approach the camels or the sleeping Bedu. Instead, Papa and I just sk'pped away into the night.

We marched westward for a long time before either of us spoke. "Will they follow us when they find we're miss-ing?" I asked.

Papa frowned. "I can't say, my nephew. Perhaps they'll just let us go. They're sure we'll die in the desert anyway."

There wasn't much I could say to that. From then on, we just concentrated on putting as much distance be-tween us and them as we could, heading off at a right angle to the direction we'd traveled with them during the day, I prayed that if we crossed a desert track in the night we'd see it. It was our only hope of finding a well.

We had the stars as guides, and we trudged westward for two hours, until Papa announced that he had to stop and rest. We'd been traveling against the dunes, which ran from west to east, due to the prevailing winds. The westward slope of each dune was smooth and gradual, but the east side, which we'd have to climb, was usually high and steep.

Consequently, we were making long detours as we tried to cross each hill at one of its low shoulders. It was slow, tiring, zigzag progress, and we couldn't have covered more than a mile or two as the sand grouse flies. We sat panting beside each other at the base of yet another monstrous cliff of sand. I opened my canteen and gulped down a mouthful before I realized how brackish and alkaline it was. "Praise Allah," I groaned, "well be lucky if this water doesn't kill us before the sun does."

Papa had drunk his fill, too. "It is not sweet water, my nephew," he said, "but there is very little sweet water in the desert. This is the water the Bedu drink almost every day of their lives."

I'd known that the nomads lived harsh, desperate lives, but I was beginning to learn that I'd undervalued their skill at forcing a living from this most inclement environment. "Why don't they just go somewhere else?" I asked, capping my canteen again.

Papa smiled. "They are proud people. They get satis-faction in their ability to exist here, in a place that means death for any outsider. They scorn the softness and luxury of villages and towns."

"Yeah, you right. Luxuries like fresh water and actual food."

We stood up and started walking again. It was now about midnight. The path across the dunes didn't get any easier, and in a little while I could hear Papa's heavy breathing. I worried about the old man's condition. My own body was beginning to protest this unaccustomed ex-ercise.

The stars turned slowly overhead, and when I looked at my watch again, it was half past one. Maybe we'd come"

another mile.

Papa estimated that the Rub al-Khali was about seven hundred and fifty miles west to east, and three hundred miles north to south. I figured it was likely that the mili-tary chopper had dropped us smack in the middle, so figuring a generous mile per hour, walking eight hours a night, we could get out of the Empty Quarter in, oh, just under forty-seven days. If we could also have a gigantic caravan of support equipment and supplies trailing along behind us. ( We rested again, drank some more of the bitter water, and headed off on the last leg of the night's journey. We were both too tired to talk. I lowered my head against the wind, which was constantly flinging sand into our faces. Ijust kept putting one foot in front of the other. I told myself that if Friedlander Bey had the resolve to keep i moving, so did I.

We reached our limit about four o'clock, and col-lapsed in utter exhaustion. The sun wouldn't rise for an-other hour or so, but the idea of going any farther that night was out of the question. We stopped beneath the ; vertical face of a gigantic dune, which would give us some protection from the wind. There we drank as much water as we could hold, and then prepared to sleep. I removed my beautiful royal blue robe and covered Papa with it. Then I huddled in a fetal position within my gallebeya and fell into cold, restless sleep. I kept waking and falling back to sleep, and I was troubled by confused, anxious dreams. I was aware after a while that the sun had risen, and I knew the best thing would be to stay asleep as long as possible during the hot day. I pulled the gallebeya up over my head, to protect my face and scalp from burning. Then I pretended that everything was just fine, and closed my eyes. It was about ten o'clock when I realized that I wasn't going to be able to sleep any later. The sun was beating down on me, and I could feel the exposed areas of skin burning. Friedlander Bey woke up then, too, and he didn't look as if he'd rested any better than I had.

"Now we must pray," he said. His voice sounded peculiar and hoarse. He struck the sand in front of him with his palms, and rubbed the sand on his face and hands. I did the same. Together we prayed, thanking Allah for giving us His protection, and asking that if it was His will, we might survive this ordeal. Each time I joined in worship with Papa, I was filled with peace and hope. Somehow, being lost in this wilder-ness had made the meaning of our religion clear to me. I wish it hadn't taken such a drastic demonstration to make me understand my relationship to Allah.

When we'd finished, we drank as much water as ve could hold. There wasn't much left in our canteens, but we didn't see any reason to discuss that fact. "My nephew," the old man said, "I think it would be wise to bury ourselves in the sand until evening."

That sounded crazy to me. "Why?" I asked. "Won't we bake ourselves like a lamb pie?"

"The deeper sand will be cooler than the surface," he said. "It will keep our skin from burning any further, and it will help reduce our loss of water through perspiration."

Once again, I shut up and learned something. We dug shallow pits and covered ourselves over with the sand. At one point, I noted to myself how very like graves they were. I was surprised to find that my body seemed to enjoy the experience. The warm sand soothed my aching muscles, and I was able to relax for the first time since we'd been snatched at the amir's celebration. In fact, after a while, listening to the murmurous buzzing of insects, I dozed off into a light sleep. The day passed slowly. I had my gallebeya pulled up over my head again, so I couldn't see anything.

There was nothing to do but lie there in the sand and think and plan and indulge in fantasies. After a few hours, I was startled to hear a low vibrat-ing hum. I couldn't imagine what it could be, and at first I thought it was only a ringing noise in my ears. It didn't go away, however, and if anything it got louder. "Do you hear that, O Shaykh?" I called.

"Yes, my nephew. It is nothing."

By now I was convinced that it was the warning whine of an approaching aircraft. I didn't know if that was good news or bad. The sound grew louder, until it was almost a shriek. I couldn't stand not being able to see, so I pushed my hands up out of the sand and pulled down the neck of my gallebeya.

There was nothing there. The buzzing had increased in volume until the aircraft should have been visible above our heads, but the sky was empty and blue. Then sud-denly, as the wind shifted direction, everything fell silent again.

The loud noise did not fade away but disappeared abruptly. "What was that?" I asked, bewildered.

"That, O Clever One, was the famous 'singing sands.' It is a very rare privilege to hear it."

"The sand made that sound? It was like the roaring of an engine!"

"They say it is made by one layer of sand slipping over another, nothing more."

Now I felt dumb for getting so upset over a little hum-ming noise created by a sand dune. Papa, however, was not one to laugh or mock me, and I was grateful for that. I covered myself in the sand again and told myself not to be such a fool.

About five o'clock, we emerged from our sandy beds and prepared for the night's exertions. We prayed and drank the brackish water, and then headed off toward the west again. After we'd walked for half an hour, I had a brilliant idea.

I took out my rack of neuralware and chipped in the special daddy that blocked thirst. Immedi-ately, I felt refreshed.

This was a dangerous illusion, be-cause although I didn't feel thirsty-and wouldn't again, as long as I had that daddy chipped in-my body was still dehydrating at the same rate. Still, I felt that I could go on without water longer now, and so I gave my canteen to Papa. "I can't take this from you, my nephew," he said.

"Sure you can, O Shaykh," I said. "This add-on will keep me from suffering for as long as our canteens do the same for you. Look, if we don't find more water soon, we'll both die anyway."

"That's true, my darling, but-"

"Let's walk, my grandfather," I said.

The sun began to set and the air began to get cooler. We took a rest stop some time later, and we prayed. Papa finished all the water in one of the canteens. Then we pushed on.

I was beginning to feel very hungry, and I realized that except for the crummy dates of the Bayt Tahiti, the last meal I'd eaten had been almost forty-eight hours ago, at the amir's palace. I was lucky, because I had a daddy that blocked hunger, too. I chipped it in, and the hollow pangs in my belly disappeared. I knew that Papa must be ravenous, but there was nothing I could do about that. I put everything out of my mind except making tracks across the remainder of the Empty Quarter.

Once, when we'd topped the crest of a high dune, I turned to look back. I saw what I thought was a smudge ofdust rising in the pale moonlight from behind a distant dune. I prayed to Allah that it wasn't the Bayt Tabiti com-ing after us. When I tried to point it out to Friedlander Bey, I couldn't find the dust cloud again.-Maybe I'd imag-ined it.

The vast desert was good for that kind of halluci-nation.

After the second hour, we had to rest. Papa's face was drawn and haggard. He opened his other canteen and drained it dry. All our water was now gone. We looked at each other wordlessly for a moment. "I testify that there is no god but God," said Papa in a quiet voice.

"I testify that Muhammad is the Prophet of God," I added. We got up and continued our march.

After a while, Papa fell to his knees and began retch-ing. He had nothing in his belly to vomit, but his spasms were long and violent. I hoped he wasn't losing much water. I knew that nausea was one of the first signs of severe dehydration. After a few minutes, he waved a hand weakly to let me know he wanted to keep going. From then on, I was more frightened than ever. I had no more illusions that we'd be able to save ourselves without a miracle.

I began to experience severe muscle cramps, and for the third time I turned to my moddy rack. I chipped in the pain-blocking daddy, knowing that I was going to be in pretty terrible shape if I ever lived to pop it out again. As my friend Chiriga likes to say, "Paybacks are a bitch."

About midnight, after another rest period, I noticed that Papa had begun to stagger. I went up to him and touched his shoulder. He faced me, but his eyes seemed unfocused. "What is it, my son?" he said. His voice was thick and his words indistinct.

"How are you feeling, O Shaykh?"

"I feel . . . strange. I'm not hungry anymore, which is a blessing, but I have a terrible headache. There are many little bright spots in front of my eyes; I can barely see in front of me. And there is the most annoying tin-gling in my arms and legs. Unfortunate symptoms."

"Yes, O Shaykh."

He looked up at me. For the first time in all the time I'd known him, he had genuine sadness in his eyes. "I do not wish to walk anymore."

"Yes, O Shaykh," I said. "Then I will carry you."

He protested, but he didn't do a very good job of it. I begged his forgiveness, then picked him up and slung him over my shoulder. I wouldn't have been able to haul him fifty yards without the daddies, which were damping out every last unpleasant signal my body was sending to my brain. I went on with a blithe, completely false sense of well-being. I wasn't hungry, I wasn't thirsty, I wasn't tired, and I didn't even ache. I even had another daddy I could use if I started to feel afraid. In a little while, I realized that Papa was muttering deliriously. It was up to jne to get us both out of this mess. I just gritted my teeth and went on. My amped brain was ridiculously confident that I'd emerge victorious against the most murderous desert in the world.

The night passed. I plodded my way through the swirling sand like a robot. All the while, my body was suffering the same debilitating effects of dehydration that had struck down Papa, and fatigue poisons were building up in my muscles.

The sun came up behind me, and I felt the heat grow on the back of my head and neck. I trudged on through the morning. Papa was no longer making any sounds at all. Once, about 8 a.m., my arms and legs just gave out. I dropped Papa heavily to the ground and fell down beside him. I let myself rest there for a little while. I knew I'd been abusing my body. I thought perhaps lying there mo-tionless for a few minutes would be helpful. I suppose I was unconscious, because the next time I checked my watch, two hours had passed. I got to my feet and picked up Papa and put him across my other shoul-der. Then I walked some more. I kept going until I collapsed again. This became a pattern, and soon I lost all track of time. The sun rose in the sky, the sun went away. The sun rose, the sun went away. I have no idea how far I managed to get. I have a vague memory of sitting on the side of a large dune, pat-ting Friedlander Bey's hand and weeping. I sat there for a long time, and then I thought I heard a voice calling my name. I picked up Papa and stumbled on, in the direction of the voice. This time, I didn't get far. I crossed two, maybe three great dunes, and then my muscles quit on me again.

I could only lie on the ground, my face half-pressed into the hot, red sand. I could see Papa's leg from the corner of my eye. I was pretty sure that I was never going to get up again. "I take refuge . . ."I murmured. I didn't have enough saliva to finish. "I take refuge with the Lord of the Worlds," I said in my mind. I passed out again. The next thing I knew, it was night. I was probably still alive. A man with a stern, lean face dominated by a huge hooked nose was bending over me. I didn't know who he was, or even if he was really there. He said something to me, but I couldn't understand his words. He wet my lips with water, and I tried to grab the goatskin bag out of his hands, but I couldn't seem to work my arms. He said something more to me. Then he reached forward and touched my implants.

With horror, I realized what he was trying to do. "No!" I cried in my cracked voice. "Please, for the love of Allah, no!"

He pulled his hand back and studied me for another few seconds. Then he opened a leather bag, removed an old-fashioned disposable syringe and a vial of some fluid, and gave me an injection. * What I really wanted was about a quart of clean, fresh water. But the shot of Sonneine was okay, too.

5.

I was now clear on the events between the kidnapping and our rescue by the Bani Salim. The days after that, however, were probably lost forever in a fog of delirium. Shaykh Hassanein had sedated me, and then pulled free the daddies. My mind and body had im-mediately been overwhelmed by a ravaging flood of ag-ony. I was grateful to Hassanein for keeping me knocked out with Sonneine until I'd begun to recover.

Noora was awake and watchful when I sat up and stretched in the morning. It took me a few seconds to recall where I was. The front and back flaps of the goat-hair tent had been thrown open, and a fresh, warm breeze passed through. I bowed my head and prayed, "Oh, that this day may be fortunate; give Thou that we see not the evil!"

"Blessings of Allah be on you, O Shaykh," said Noora. She came nearer, carrying a bowl of camel's milk and a plate of bread and hummus, a paste made of chick-peas and olive oil.

"Bismittah," I murmured, tearing off a piece of bread. "May your day be pleasant, Noora." I began wolfing down the breakfast.

"It's good to see that your appetite is back. Would you like some more?"

My mouth was crammed full, so I just nodded. Noora went out of the tent to fetch a second helping. I took a few deep breaths and experimented with moving my limbs. There was still a deep soreness in my muscles, but I felt that I could get up soon. I remembered what Hassanein had told me, that the Bani Salim would need to find new grazing for their animals very soon. I wasn't thrilled by the prospect of walking a couple of hundred miles with them, so it was probably time that I learned how to ride a camel.

Noora returned with another plate of bread and hum-mus, and I attacked it hungrily. "The old shaykh will visit you when you're finished eating," she said.

I was glad to hear that. I wanted to see how well Friedlander Bey had survived our ordeal. It wasn't over by any means, though. We still had a long distance to travel, and the conditions would be just as harsh. The lifesaving difference was that we'd be traveling with the Bani Salim, and they knew where all the wells were. "Papa and I have much to talk over," I said.

"You must plan your vengeance."

"What do you know of that?" I asked.

She smiled. I realized that she was no longer holding her head scarf over her face. "You've told me many times about the amir and the qadi and the imam and Shaykh Reda. Most of the time, you just babbled; but I under-stood enough of what you were saying, and the old shaykh told me much the same story."

I raised my eyebrows and mopped up the last dollop of hummus with a chunk of bread. "What do you think we should do?"

Her expression turned solemn. "The Bedu insist on revenge. We practically make it a necessary part of our religion. If you didn't return to your city and slay those who plotted against you, the Bani Salim wouldn't be your friends when you returned to us."

I almost laughed when I heard her speak of my re-turning to the Rub al-Khali. "Even though the man re-sponsible is a revered imam? Even though he's beloved by the fellahin of the city? Even though he's known for his goodness and generosity?"

"Then he is an imam of two faces," said Noora. "To some, he may be wise in the worship of Allah, and kind to his brothers in Islam. Yet he did this evil to you, so his true nature is corrupt. He takes the coins of your enemy, and unjustly sentences innocent men to an exile that is almost surely death. The second face renders the first false, and is an abomination in the eyes of God. It's your duty to repay his treachery with the penalty accorded by tradition."

I was startled by her vehemence. I wondered why this matter between Papa and me, on the one side, and Dr. Abd ar-Razzaq, on the other, disturbed her so much. She saw me studying her, and she blushed and covered her face with her head cloth.

"The tradition of the Bedu may not be legal in the city," I said.

Her eyes flashed. "What is legal'? There's only right and wrong. There's a story the Bedu women tell their children, about the evil imam in the well."

* "Noora, if it had been an accountant who'd done us harm, this story would be about the evil accountant in the well, right?"

"I don't even know what an accountant is," she said. "Listen, then. Maybe there was, and maybe there wasn't an evil imam of Ash-Sham, which you call Damascus, when Ash-Sham was the only city in the world. The Bedu have no need of imams, because every member of the tribe prays to God as an equal and defers to no other. The weak city folk needed an imam to help them, because they'd forgotten what it was to find their own water and make their own food, and they'd come to depend on other people to supply these things. So, too, had they come to depend on an imam to lead the way to Allah.

"Now, many of the people of Ash-Shfim still thought the evil imam was wise and good, because he made sure everyone who heard him preach gave money to their needy brothers. The imam himself never gave any of his own money, because he'd grown very fond of it. He loved gold so much that he sold his influence to one of Ash-Sham's most corrupt and ambitious citizens, "When Allah realized that the imam's heart had turned black, He sent one of His angels down to earth. The angel'sinstructions were to take the imam away into the desert, and imprison him so that he might never lead any of the people of Ash-Sham astray. The angel found the imam in his secret treasury, stacking up his piles of gold and silver coins, and cast a spell over the imam that made him fall into a deep sleep.

"The angel picked up the evil imam and carried him in the palm of his hand, and brought him to the very heart of the Rub al-Khali. The imam knew nothing of this, be-cause he was still fast asleep. The angel built a deep, deep well, and put the imam down at the very bottom, where there was only the most bitter and foul water. Then the angel caused the imam to awaken.

" Tea Allah!' cried the evil imam. 'Where am I, and how did I come to this place?'

" 'It is too late to call on God, O Son of Adam,' said the angel. His stern voice cracked like thunder in the air, and the walls of the well shook around the imam.

" 'Let me out,' said the imam fearfully, 'and I promise to change my ways! Have mercy on irie!'

" The angel shook his head, and his eyes loosed terri-ble flashes of lightning. 'It is for me neither to judge nor to have mercy. The One Judge has already condemned you to this place. Think on your deeds and repair your soul, for you have still to meet your God on the Last Day.' Then the angel departed, and left the evil imam all alone.

"A day came when the evil imam's successor, whose name was Salim and who was the founder of our tribe, came upon the well in his travels. Salim had never known the evil imam, and he was as different from him as the sun and the moon. This young man was truly kind and generous, and well beloved of all the people of Ash-Sham, who had appointed him to be their imam in recognition of his virtues.

"As Salim bent forward to peer into the well, he was startled to see that a number of creatures had fallen into it and were trapped with the evil imam. The animals begged him to release them from the deep well. Salim felt so sorry for the animals that he unwound his keffiya and lowered it into the dark hole.
