We'd ridden for many days out the coast highway toward Mauretania, the part of Algeria where I'd been born. In that time, even at its lethargic pace, the broken-down old bus had carried us from the city to some town forsaken by Allah before it even learned what its name was. Centuries come, centuries go: In the Arab world they arrive and depart loaded on the roofs of shuddering, rattling buses that are more trouble to keep in service than the long parades of camels used to be. I remembered what those bus rides were like from when I was a kid, sitting or standing in the aisle with fifty other boys and men and maybe another two dozen clinging up on the roof. The buses passed by my home then. I saw turbaned heads, heads wearing fezes or knit caps, heads in white or checked keffiyas. All men. That was something I planned to ask my father about, if I ever met him. "O my father," I would say, "tell me why everyone on the bus is a man. Where are their women?"

And I always imagined that my father -- I pictured him tall and lean with a fierce dark beard, a hawk or an eagle of a man; he was, in my vision, Arab, although I had my mother's word that he had been a French imam -- I saw my father gazing thoughtfully into the bright sunlight, framing a careful reply to his young son. "O Marîd, my sweet one," he would say -- and his voice would be deep and husky, issuing from the back of his throat as if he never used his lips to speak, although my mother said he wasn't like that at all -- "Marîd, the women will come later. The men will send for them later."

"Ah," I would say. My father could pierce all riddles. I could not pose a question that he did not have a proper answer for. He was wiser than our village shaykh, more knowledgeable than the man whose face filled the posters pasted on the wall we were pissing on. "Father," I would ask him, "why are we pissing on this man's face?"

"Because it is idolatrous to put his face on such a poster, and it is fit only for a filthy alley like this, and therefore the Prophet, may the blessing of Allah be on him and peace, tells us that what we are doing to these images is just and right."

"And father?" I would always have one more question, and he'd always be blissfully patient. He would smile down at me, put one hand fondly behind my head. "Father? I have always wanted to ask you, what do you do when you are pissing and your bladder is so full it feels like it will explode before you can relieve it and while you are pissing, just then, the muezzin--"

Saied hit me hard in the left temple with the palm of his hand. "You sleeping out here?"

I looked up at him. There was glare everywhere. I couldn't remember where the hell we were. "Where the hell are we?" I asked him.

He snorted. "You're the one from the Maghreb, the great, wild west. You tell me."

"Have we got to Algeria yet?" I didn't think so.

"No, stupid. I've been sitting in that goddamn little coffeehouse for three hours charming the warts off this fat fool. His name is Hisham."

"Where are we?"

"Just crossed through Carthage. We're on the outskirts of Old Tunis now. So listen to me. What's the old guy's name?"

"Huh? I don't remember."

He hit me hard in the right temple with the palm of his other hand. I hadn't slept in two nights. I was a little confused. Anyway, he got the easy part of the job: Sitting around the bus stops, drinking mint tea with the local ringleaders and gossiping about the marauding Christians and the marauding Jews and the marauding heathen niggers and just in general being goddamn smooth; and I got the piss-soaked alleys and the flies. I couldn't remember why we divided this business up like that. After all, I was supposed to be in charge -- it was my idea to find this woman, it was my trip, we were using my money. But Saied took the mint tea and the gossip, and I got -- well, I don't have to go into that again.

We waited the appropriate amount of time. The sun was disappearing behind a western wall; it was almost time for the sunset call to prayer. I stared at Saied, who was now dozing. Good, I thought, now I get to hit him in the head. I had just gotten up and taken one little step, when he looked up at me. "It's time, I guess," he said, yawning. I nodded, didn't have anything to add. So I sat back down, and Saied the Half-Hajj went into his act.

Saied is a natural-born liar, and it's a pleasure to watch him hustle. He had the personality module he liked best plugged into his brain -- his heavy-duty, steel-belted, mean mother of a tough-guy moddy. Nobody messed with the Half-Hajj when he was chipping that one in.

Back home in the city, Saied thought it was beneath him to earn money. He liked to sit in the cafés with me and Mahmoud and Jacques, all day and all evening. His little chicken, the American boy everybody called Abdul-Hassan, went out with older men and brought home the rent money. Saied liked to sneer a lot and wear his gallebeya cinched with a wide black leather belt, which was decorated with shiny chrome steel strips and studs. The Half-Hajj was always careful of his appearance.

What he was doing in this vermin-infested roadside slum was what he called fun. I waited a few minutes and followed him around the corner and into the coffeehouse. I shuffled in, unkempt, filthy, and took a chair in a shadowy corner. The proprietor glanced at me, frowned, and turned back to Saied. Nobody ever paid any attention to me. Saied was finishing the tail-end of a joke I'd heard him tell a dozen times since we'd left the city. When he came to the payoff, the shopkeeper and the four other men at the long counter burst into laughter. They liked Saied. He could make people like him whenever he wanted. That talent was programmed into an add-on chip snapped into his bad-ass moddy. With the right moddy and the right daddy chips, it didn't matter where you'd been born or how you'd been raised. You could fit in with any sort of people, you could speak any language, you could handle yourself in any situation. The information was fed directly into your short-term memory. You could literally become another person, Ramses II or Buck Rogers in the 25th Century, until you popped the moddy and daddies out.

Saied was being rough and dangerous, but he was also being charming, if you can imagine that combination. I watched the shopowner reach and grab the teapot. He poured some into the Half-Hajj's glass, slopping some more on the wooden counter. Nobody moved to mop it up. Saied raised the glass to drink, then slammed it down again. "Yaa salaam!" he roared. He leaped up.

"What is it, O my friend?" asked Hisham, the proprietor.

"My ring!" Saied shouted. He was wearing a large gold ring, and he'd been waving it under the old man's nose for two solid hours. It had had a big, round diamond in its center.

"What's the matter with your ring?"

"Look for yourself! The stone -- my diamond -- it's gone!"

Hisham caught Saied's flapping arm and saw that, indeed, the diamond was now missing. "Must have fallen out," the old man said, with the sort of folk wisdom you find only in these petrified provincial villages.

"Yes, fallen out," said Saied, not calmed in the least. "But where?"

"Do you see it?"

Saied made a great show of searching the floor around his stool. "No, I'm sure it's not here," he said at last.

"Then it must be out in the alley. You must've lost it the last time you went out to piss."

Saied slammed the bar with his heavy fist. "And now it's getting dark, and I must catch the bus."

"You still have time to search," said Hisham. He didn't sound very confident.

The Half-Hajj laughed without humor. "A stone like that, worth four thousand Tunisian dinars, looks like a tiny pebble among a million others. In the twilight I'd never find it. What am I to do?"

The old man chewed his lip and thought for a moment. "You're determined to leave on the bus, when it passes through?" he asked.

"I must, O my brother. I have urgent business."

"I'll help you if I can. Perhaps I can find the stone for you. You must leave your name and address with me; then if I find the diamond, I'll send it to you."

"May the blessings of Allah be on you and on your family!" said Saied. "I have little hope that you'll succeed, but it comforts me to know you will do your best for me. I'm in your debt. We must determine a suitable reward for you."

Hisham looked at Saied with narrowed eyes. "I ask no reward," he said slowly.

"No, of course not, but I insist on offering you one."

"No reward is necessary. I consider it my duty to help you, as a Muslim brother."

"Still," Saied went on, "should you find the wretched stone, I'll give you a thousand Tunisian dinars for the sustenance of your children and the ease of your aged parents."

"Let it be as you wish," said Hisham with a small bow.

"Here," said my friend, "let me write my address for you." While Saied was scribbling his name on a scrap of paper, I heard the rumbling of the bus as it lurched to a stop outside the building.

"May Allah grant you a good journey," said the old man.

"And may He grant you prosperity and peace," said Saied, as he hurried out to the bus.

I waited about three minutes. Now it was my turn. I stood up and staggered a couple of steps. I had a lot of trouble walking in a straight line. I could see the shopkeeper glaring at me in disgust. "The hell do you want, you filthy beggar?" he said.

"Some water," I said.

"Water! Buy something or get out!"

"Once a man asked the Messenger of God, may Allah's blessings be on him, what was the noblest thing a man may do. The reply was 'To give water to he who thirsts.' I ask this of you."

"Ask the Prophet. I'm busy."

I nodded. I didn't expect to get anything free to drink out of this crud. I leaned against his counter and stared at a wall. I couldn't seem to make the place stand still.

"Now what do you want? I told you to go away."

"Trying to remember," I said peevishly. "I had something to tell you. Ah, yes, I know." I reached into a pocket of my jeans and brought out a glittering round stone. "Is this what that man was looking for? I found this out there. Is this--?"

The old man tried to snatch it out of my hand. "Where'd you get that? The alley, right? My alley. Then it's mine."

"No, I found it. It's--"

"He said he wanted me to look for it." The shopkeeper was already gazing into the distance, spending the reward money.

"He said he'd pay you money for it."

"That's right. Listen, I've got his address. Stone's no good to you without the address."

I thought about that for a second or two. "Yes, O Shaykh."

"And the address is no good to me without the stone. So here's my offer: I'll give you two hundred dinars for it."

"Two hundred? But he said--"

"He said he'd give me a thousand. Me, you drunken fool. It's worthless to you. Take the two hundred. When was the last time you had two hundred dinars to spend?"

"A long time."

"I'll bet. So?"

"Let me have the money first."

"Let me have the stone."

"The money."

The old man growled something and turned away. He brought a rusty coffee can up from under the counter. There was a thick wad of money in it, and he fished out two hundred dinars in old, worn bills. "Here you are, and damn your mother for a whore."

I took the money and stuffed it into my pocket. Then I gave the stone to Hisham. "If you hurry," I said, slurring my words despite the fact that I hadn't had a drink or any drugs all day, "you'll catch up with him. The bus hasn't left yet."

The man grinned at me. "Let me give you a lesson in shrewd business. The esteemed gentleman offered me a thousand dinars for a four-thousand dinar stone. Should I take the reward, or sell the stone for its full value?"

"Selling the stone will bring trouble," I said.

"Let me worry about that. Now you go to hell. I don't ever want to see you around here again."

He needn't worry about that. As I left the decrepit coffeehouse, I popped out the moddy I was wearing. I don't know where the Half-Hajj had gotten it; it had a Malaccan label on it, but I didn't think it was an over-the-counter piece of hardware. It was a dumbing-down moddy; when I chipped it in, it ate about half of my intellect and left me shambling, stupid, and just barely able to carry out my half of the plan. With it out, the world suddenly poured back into my consciousness, and it was like waking from a bleary, drugged sleep. I was always angry for half an hour after I popped that moddy. I hated myself for agreeing to wear it, I hated Saied for conning me into doing it. He wouldn't wear it, not the Half-Hajj and his precious self-image. So I wore it, even though I'm gifted with twice the intracranial modifications as almost anybody else around, enough daddy capacity to make me the most talented son of a bitch in creation. And still Saied persuaded me to damp myself out to the point of near vegetability.

On the bus, I sat next to him, but I didn't want to talk to him or listen to him gloat.

"What'd we get for that chunk of glass?" he wanted to know. He'd already replaced the real diamond in his ring.

I just handed the money to him. It was his game, it was his score. I couldn't have cared less. I don't even know why I went along with him, except that he'd said he wouldn't come to Algeria with me unless I did.

He counted the bills. "Two hundred? That's all? We got more the last two times. Oh, well, what the hell -- that's two hundred dinars more we can blow in Algiers. 'Come with me to the Kasbah.' Little do those gazelle-eyed boys know what's stealing toward them even now, through the lemon-scented night."

"This stinking bus, that's what, Saied."

He looked at me with wide eyes, then laughed. "You got no romance in you, Marîd," he said. "Ever since you had your brain wired, you been no fun at all."

"How about that." I didn't want to talk anymore. I pretended that I was going to sleep. I just closed my eyes and listened to the bus thumping and thudding over the broken pavement, with the unending arguments and laughter of the other passengers all around me. It was crowded and hot on that reeking bus, but it was carrying me hour by hour nearer to the solution of my own mystery. I had come to a point in my life where I needed to find out who I really was.

The bus stopped in the Barbary town of Annaba, and an old man with a grizzled gray beard came aboard selling apricot nectar. I got some for myself and some for the Half-Hajj. Apricots are the pride of Mauretania, and the juice was the first real sign that I was getting close to home. I closed my eyes and inhaled that delicate apricot aroma, then swallowed a mouthful of juice and savored the thick sweetness. Saied just gulped his down with a grunt and gave me a blunt "Thanks." The guy's got all the refinement of a dead bat.

The road angled south, away from the dark, invisible coast toward the city of Constantine. Although it was getting late, almost midnight, I told Saied that I wanted to get off the bus and grab some supper. I hadn't eaten anything since noon. Constantine is built on a high limestone bluff, the only ancient town in eastern Algeria to survive through centuries of foreign invasions. The only thing I cared about, though, was food. There is a local dish in Constantine called chorba beida bel kefta, a meatball soup made with onions, pepper, chickpeas, almonds, and cinnamon. I hadn't tasted it in at least fifteen years, and I didn't care if it meant missing the bus and having to wait until tomorrow for another, I was going to have some. Saied thought I was crazy.

I had my soup, and it was wonderful. Saied just watched me wordlessly and sipped a glass of tea. We got back on the bus in time. I felt good now, comfortably full and warmed by a nostalgic glow. I took the window seat, hoping that I'd be able to see some familiar landscape as we passed through Jijel and Mansouria. Of course, it was as black as the inside of my pocket beyond the glass, and I saw nothing but the moon and the fiercely twinkling stars. Still, I pretended to myself that I could make out landmarks that meant I was drawing closer to Algiers, the city where I had spent a lot of my childhood.

When at last we pulled into Algiers sometime after sunrise, the Half-Hajj shook me awake. I didn't remember falling asleep. I felt terrible. My head felt like it had been crammed full of sharp-edged broken glass, and I had a pinched nerve in my neck, too. I took out my pill case and I stared into it for a while. Did I prefer to make my entrance into Algiers hallucinating, narcotized, or somnambulant? It was a difficult decision. I went for pain-free but conscious, so I fished out eight tabs of Sonneine. The sunnies obliterated my headache -- and every other mildly unpleasant sensation -- and I more or less floated from the bus station in Mustapha to a cab.

"You're stoned," said Saied when we got to the back of the taxi. I told the driver to take us to a public data library.

"Me? Stoned? When have you ever known me to be stoned so early in the morning?"

"Yesterday. The day before yesterday. The day before that."

"I mean except for then. I function better with a ton of opiates in me than most people do straight."

"Sure you do."

I stared out the taxi's window. "Anyway," I said, "I've got a rack of daddies that can compensate."

"Marîd Audran, Silicon Superman."

"Look," I said, annoyed by Saied's attitude, "for a long time I was terrified of getting wired, but now I don't know how I ever got along without it."

"Then why the hell are you still decimating your brain cells with drugs?" asked the Half-Hajj.

"Call me old-fashioned. Besides, when I pop the daddies out, I feel terrible. All that suppressed fatigue and pain hit me at once."

"And you don't get paybacks with your sunnies and beauties, right? That what you're saying?"

"Shut up, Saied. Why the hell are you so concerned all of a sudden?"

He looked at me sideways and smiled. "The religion has this ban on liquor and hard drugs, you know." And this coming from the Half-Hajj who, if he'd ever been inside a mosque in his life, was there only to check out the boys' school.

So in ten or fifteen minutes the cab driver let us out at the library. I felt a peculiar nervous excitement, although I didn't understand why. All I was doing was climbing the granite steps of a public building; why should I be so wound up? I tried to occupy my mind with more pleasant thoughts.

Inside, there were a number of terminals vacant. I sat down at the gray screen of a battered Bab el-Marifi. It asked me what sort of search I wanted to conduct. The machine's voice synthesizer had been designed in one of the North American republics, and it was having a lot of trouble pronouncing Arabic. I said, "Name," then "Enter." When the cursor appeared again, I said, "Monroe comma Angel." The data deck thought about that for a while, then white letters began flicking across its bright face:

Angel Monroe 16, Rue du Sahara (Upper) Kasbah Algiers Mauretania 04-B-28

"Inshallah," murmured Saied. If God wills.

We went back out into the hot, steamy morning to find another taxi. It didn't take long to get from the library to the Kasbah. There wasn't as much traffic as I remembered from my childhood -- not vehicular traffic, anyway; but there were still the slow, unavoidable battalions of heavily-laden donkeys being cajoled through the narrow streets.

Number 16 was an exhausted, crumbling brick pile with two bulging upper stories that hung out over the cobbled street. The apartment house across the way did the same, and the two buildings almost kissed above my head, like two dowdy old matrons leaning across a back fence. There was a jumble of mailslots, and I found Angel Monroe's name scrawled on a card in fading ink. I jammed my thumb on her buzzer. There was no lock on the front door, so I went in and climbed the first flight of stairs. Saied was right behind me.

Her apartment turned out to be on the third floor, in the rear. The hallway was carpeted, if that's the right word, with a dull, gritty fabric that had at one time been maroon. The traffic of uncountable feet had completely worn through the material in many places, so that the dry gray wood of the floor was visible through the holes. The walls were covered with a filthy tan wallpaper, hanging down here and there in forlorn strips. The air had an odd, sour tang to it, as if the building were occupied by people who had come there to die, or who were certainly sick enough to die but instead hung on in lonely misery. From behind one door I could hear a family battle, complete with bellowed threats and crashing crockery, while from another apartment came insane, high-pitched laughter and the sound of flesh loudly smacking flesh. I didn't want to know about it.

I stood outside the shabby door to Angel Monroe's flat and took a deep breath. I glanced at the Half-Hajj, but he just gave me a shrug and pointedly looked away. Some friend. I was on my own. I told myself that nothing weird was going to happen -- a lie just to get myself to take the next step -- and then I knocked on the door. There was no response. I waited a few seconds and knocked again, louder. This time I heard the rattle and squeak of bedsprings and the sound of someone coming slowly to the door. The door swung open. Angel Monroe stared out, trying very hard to focus her eyes.

She was a full head shorter than me, with bleached blonde hair curled tightly into an arrangement I would call "ratty." Her black roots looked as if no one had given them much attention since the Prophet's birthday. Her eyes were banded with dark blue and black makeup, in a manner that brought to mind the more colorful Mediterranean saltwater fish. The rouge she wore was applied liberally, but not quite in the right places, so she didn't look so much wantonly sexy as she did feverishly ill. Her lipstick, for reasons best known to Allah and Angel Monroe, was a kind of pulpy purple color; her lips looked like she'd bought them first and forgot to put them in the refrigerator while she shopped for the rest of her face.

Her body led me to believe that she was too old to be dressed in anything but the long white Algerian haik, with a veil conservatively and firmly in place. The problem was that this body had never seen the inside of a haik. She was clad now in shorts so small that her well-rounded belly was bending the waistband over. Her sagging breasts were not quite clothed in a kind of gauzy vest. I knew for certain that if she sat in a chair, you could safely hide the world's most valuable gem in her navel and it would be completely invisible. Her legs were patterned with broken veins like the dry chebka valleys of the Mzab. On her broad, flat feet she wore tattered slippers with the remains of pink fuzzy bows dangling loose.

To tell the truth, I felt a certain disgust. "Angel Monroe?" I asked. Of course, that wasn't her real name. She was at least half Berber, as I am. Her skin was darker than mine, her eyes as black and dull as eroded asphalt.

"Uh huh," she said. "Kind of early, ain't it?" Her voice was sharp and shrill. She was already very drunk. "Who sent you? Did Khalid send you? I told that goddamn bastard I was sick. I ain't supposed to be working today, I told him last night. He said it was all right. And then he sends you. Two of you, yet. Who the hell does he think I am? And it ain't like he don't have no other girls, either. He could have sent you to Efra, that whore, with her plug-in talent. If I ain't feeling good, it don't bother me if he sends you to her. Hell, I don't care. How much you give him, anyway?"

I stood there, looking at her. Saied gave me a jab in the side. "Well, uh, Miss Monroe," I said, but then she started chattering again.

"The hell with it. Come on in. I guess I can use the money. But you tell that son of a bitch Khalid that--" She paused to take a long gulp from the tall glass of whiskey she was holding. "You tell him if he don't care enough about my health, I mean, making me work when I already told him I was sick, then hell, you tell him there are plenty of others I can go work for. Anytime I want to, you can believe that."

I tried twice to interrupt her, but I didn't have any success. I waited until she stopped to take another drink. While she had her mouth full of the cheap liquor, I said, "Mother?"

She just stared at me for a moment, her filmy eyes wide. "No," she said at last, in a small voice. She looked closer. Then she dropped her whiskey glass to the floor.
