Bilal shrugged. ‘The caliph needs cut stone for his new city, and it is easier to quarry it from the past than from the ground.’
We made our way into the shade at the base of the largest pyramid and dismounted. Bilal had brought food — figs and dates and cheese — and also wine and sherbet. The slaves laid carpets on the hot sand, and we sat and ate in the shadow of antiquity. Our Turkish guards stayed on their horses and ate in the saddle, watching us from a little distance.
‘Do they expect us to steal a camel and escape into the desert?’ I wondered, pulling a fig from one of the baskets. A little way across the sand, the African boy sat in the shade of his hobbled camel and watched us impassively. Impulsively, I threw him the fig and watched his squinting eyes widen. He snatched it from the air, peeled back the green skin and sucked out the purple flesh and seeds. A trail of dark juice spilled onto the desert beside him.
Nikephoros looked away, bored or embarrassed, and pretended to examine the construction of the pyramid. Bilal glanced at me approvingly. It was a rare moment of empathy after so many weeks of guarded emotion, and I was suddenly desperate to make more of it.
I swept my arm across the desert, and back towards the river valley. ‘Is this your country?’
He shrugged. ‘I was born here.’
That wasn’t what I had meant. ‘Where are your people from?’
‘From the south.’ He spat a date seed onto the sand. ‘But that is not my country.’
‘Why not?’
‘My mother was brought to Egypt when she was a girl. I was born here. I have campaigned in Palestine, in Syria and in Arabia, but I have never set eyes on Zanj, where she came from. How could that be my home?’
It seemed a strange and rootless way to live. ‘I was born in Isauria, but I have not seen it in fifteen years. The Turks have governed it for most of that time — the emperor only reconquered it this past spring. But it is still my homeland.’
‘And when your emperor conquered it — what happened to all the Turks who were born there?’
‘I suppose they went back to their homelands in the East.’ I saw the look Bilal was giving me. ‘They did not belong there. It was Byzantine land.’
‘And Jerusalem. Is that Byzantine land as well?’
‘It’s Christian land,’ I said defensively.
‘And when did Christians last own it?’
‘Hundreds of years ago. But that is no reason why they should not have it again. Otherwise, you have nothing more than the rule of conquest.’
Bilal leaned sideways and sketched an abstract circle in the sand next to our carpet. ‘Of course I believe in the rule of conquest. Show me a soldier who doesn’t.’
‘A defeated soldier,’ said Nikephoros, who had shown every sign of ignoring us until then. Somehow, his attention now cast a chill on the conversation, and we lapsed into silence.
After lunch, I excused myself from the party and wandered across the desert to the northernmost of the pyramids. The Turkish guards watched me go but did not follow. There was nowhere I could have escaped to.
The pyramid was so vast that long before you entered its shadow you ceased to see it for what it was. Its geometric perfection, so obvious from afar, distorted until it became nothing more than a huge wall lifting out of the sand. Only as I reached its foot did it change again, resolving itself into a giant staircase, which seemed to rise to the heavens. Captivated, I began to climb without even thinking. The stripped courses were pitted and irregular, and I had to scramble to haul myself over each tier. Before I was even halfway up, my tunic was filthy with dust and sweat. Too late, I remembered I was supposed to be a representative of the emperor and probably above such things.
I paused in my ascent and looked down, shading my eyes with my hand. The green-brown smear of the Nile valley trailed away to the north, a thin vein of life between two apparently endless deserts. I could see the towers of al-Qahira, and the sprawling ruins of Fustat, the ghost city, beside it. Ahead and to my right, the blows of the masons’ chisels rung in the still air.
It was too hot to sit there long, but I did not want to go back to Nikephoros and Bilal so soon. I rose, and edged my way around the pyramid along the uneven course. As I came around to the western face I looked down, and saw two horses tethered to a fallen rock at the pyramid’s base. Even in this alien place, it seemed the Turkish guards would not allow me too long a leash, though I could not see the riders.
Sweating profusely, I reached the next corner and turned onto the northern side. I paused. A few tiers below me, and not quite in the centre of the face, a large gap broke the regular lines of stone. At first I thought it must just be where the caliph’s workmen had cut away a deeper layer, but as I scrambled closer I saw that it was actually a hole, the mouth of a sloping tunnel leading down into the unseen depths of the pyramid. The stones about it were jagged and raw, as if the pyramid had been smashed open, while the walls of the tunnel within were impeccably smooth, inviting and sinister. I shivered, despite the heat. I had pried into pagan temples once before and found nothing but blood and wickedness. On the other hand, confronted with a dark cave, who does not long to know what lies within?
It was then that I heard the scream. It shrilled out of the tunnel as if squeezed from the ancient stones themselves, as if the ghosts of the pharaohs had stirred in their coffins. I stepped back, almost over the edge of the ledge, and flailed my arms furiously to keep my balance. The effort seemed to right my senses. I believed there were demons in the world, of course, and I believed that evil lurked in the pagan inheritance of our ancestors. Sometimes I had felt it. But along with the scream, just after it, I had heard something else: a voice raised in anger. And as I peered at the sand that had drifted into the entrance, I could see two sets of fresh footprints — and two snaking lines as if something, or someone, had been dragged between them. Ghosts and spirits might dwell in the pyramid, but the sounds I had heard were the sounds of men. Crossing myself twice, I stepped into the darkness.
I had expected that the monumental scale of the building would be matched within: I had imagined cavernous chambers, high galleries and vast columns rising into darkness. Instead, almost immediately, the passage tapered into a shaft so small that I had to first crouch, then crawl — though it was so steep that I was grateful to be able to brace myself against the low ceiling for fear of losing my grip entirely and sliding forwards. . how far down? My misgivings mounted as the light from outside vanished behind me, but almost immediately my eyes seemed to adjust to the gloom. No — something was illuminating the passage before me. A flickering orange glow, a torch or a fire, licked up the tunnel walls from below. Blood rushed into my head, paining and dizzying me. I suddenly saw what a lunatic mistake this had been; I wanted to turn back, but the tunnel was so thin I did not have the space. Would it ever release me, or would I have to crawl on my belly all the way into the depths of hell? All I could do was hasten my pace.
At last, the passage opened out. The air inside was cool and stale, smeared with the oily smoke of a lamp set in a niche in the wall. By its billowing light I could see I had entered a chamber tall enough that I could stand. At the far end, a black granite boulder blocked the passage beyond, though a heap of rubble suggested someone had once tried to burrow around it. For myself, I no longer had any desire to penetrate deeper into the depths of the pyramid: I would have turned around and counted myself lucky just to see the sky again. But I could not. The smoky lamplight cast three shadows over the polished granite: two were Turkish guards, their swords and belts unbuckled from their waists and their robes hanging open; the third was the black-skinned boy who had led my camel, now lying cowering on the floor. He was completely naked, and I saw a balled-up cloth in a corner where his thin tunic had been ripped from his body.
I spoke without thinking if I would be understood, or what my words would provoke. ‘Stop!’
The two guards turned. The boy, who had seen me first, lifted himself on his hands like a dog scenting his master, though there was little hope on his face.
‘Stop,’ I said again. The sudden act of standing up had left me dizzy, and there was less conviction in my voice this time. The guard to my left scowled, then stepped towards me and spat out a stream of angry words. I shook my head dumbly, understanding nothing but terribly fearful for what I had begun. I glanced back at the boy: he had crawled over to his discarded tunic and reached out for it, but as he did so the second guard stamped a heavy boot on his hand. The gruesome crack of bone echoed around the chamber; the boy howled, and flung himself back into the far corner where he lay, whimpering, not even bothering to cover himself. How old could he be — ten? Twelve?
