The few people he had seen were like the wretches he had once watched sifting through rubbish on the Thames foreshore on a foggy London morning, only here they were naked and there was no tide to wash away the filth of the river. It was as if the city had collapsed in exhaustion during the day, and what little energy remained – for scouring the alleyways yet again for anything edible, for raising ever more fetid water from the river – came out in a brief burst at dusk, before it dissipated again and the night-time bombardment of the city resumed. The people had been living in the shadow of death for too long to care what tomorrow might bring; they knew as Mayne knew that this day could be their last, that the arrival of the steamers with the relief force would surely provoke the Mahdi to order a final assault in which everything squalid would be cleansed, in which the city would be cleared of its suffocating pallor and the divine light would be allowed to shine through, in which all those who did not see it and who still clung to Gordon would be raped and mutilated and butchered.
He turned again to the foreshore, and spotted a group of women and children dragging two corpses down to the river; they left them in the mud and scurried back up the bank. He looked at the dark pool below the bodies, and wondered whether the vultures were the only ones here with a taste for human flesh. Shaytan had told him that the slave-traders had captured crocodiles from the Nile and kept them in special underground tanks, feeding them with those who had crossed them. Perhaps these women were doing the same, leaving offerings to beasts that had been set free in the river but still lingered nearby, expecting a feast of death. He remembered the underground chamber beside the cataract and the image of the ancient Egyptian crocodile god Sobek. Perhaps these people, in this place too shrouded in horror for the divine light to break through, had reverted to worshipping the beasts the ancients believed radiated the divine presence. He wondered whether Gordon had seen that too, when he had first come here, and whether his zeal to lift the shroud and bring light to these people had brought darkness down upon himself, a darkness that Mayne could now see swallowing up the city, leaving only the lights of the palace flickering in the gloom.
He put his hand on his forehead, feeling the sticky dampness his fingers had picked up from the mud-brick wall. Everything seemed to be covered in a viscous overlay, as if the city were decaying and its putrescence seeping out around the edges, over the Nile and into the desert beyond. He remembered what this place had been before: a city whose population were either slave-dealers or the slaves themselves, people who had either discarded morality or whose morality had been destroyed when they were put in chains. A city like that had been in a state of decay long before the siege had begun, its rotting core concealed perhaps by the bustle of trade and the thin carapace of civilised normality provided by the governor and his administration. With those gone it was as if the horror had been allowed to surface, the decay to ooze out. The darkness he saw now in the corners and alleyways was not merely shadows, but something more substantial, a malaise that would soon swallow the skeletal houses and leave nothing there at all, a decaying mound eviscerated of life, like the ancient city-mounds he had seen in the desert to the north.
Seeing the emaciated forms of the people had made him conscious of his own body, of the sparseness of muscle on his forearms, the gaunt cheeks beneath his beard. It was as if all that had hardened him, toughened him up for the desert journey, had in reality been preparation for Khartoum, reducing him to a state where he could be absorbed by the city and stand alongside others as a supplicant to the man who had arrived in their midst like a prophet. But the spareness of his frame scarcely registered against those he had seen on the other shore. This had been a city without food for weeks, apart from the dwindling supply of grain that Gordon must have kept for his own people. The only conceivable sustenance could have come from the corpses that mounted every day, dead through starvation or disease or gunfire; even so, their withered bodies could scarcely have provided palatable nourishment. He caught himself up, suddenly horrified by the ease with which he had assumed the worst. But contemplating Khartoum was like looking at one of the medieval paintings of hell that so fascinated Corporal Jones, where imagining the concealed horrors was worse than the visible images. He wondered how many other cities had gone this way, their inhabitants reduced to living without meaning, solely for survival, until they were mere shadows; and how many of the stark white ruins he had visited, places like Akhenaten’s capital Amarna, had ended their days not in quiet abandonment but in squalor and amorality and putrescence, reeking of decay.
He heard a footfall outside the wall, and Charrière slid alongside him and squatted down. ‘I’ve found a small reed boat, about the size of a canoe. I’ve used my knife to make you a paddle from a piece of plank. It’s crude, but it will do. The channel will take you to within a hundred yards of the island, so you will need to go without making a sound, just as we used to when we crept up on deer on the shore of our lake in the forest.’
It was the first time Charrière had spoken of their past. Mayne had a sudden vision of the two of them as boys half a lifetime ago in Canada, of the birch-bark canoe that Charrière’s father had made him, of the trust they had had in him that he had betrayed by leaving. He started to say something, to tell Charrière how much he wished they were back there now, how sorry he was for letting him down all those years ago, but then he looked into Charrière’s eyes, cold, hard, dark, and said nothing. He raised himself up, keeping below the level of the walls. ‘A reed boat is good. There will be no noise if I go over a rock.’
Charrière looked back out over the desert, scanning the gloom and frowning.
‘What are you thinking?’ Mayne asked.
‘There are no camels, but I sense it. There are others there.’
Mayne stared at him. ‘Our pursuers? There’s been no sign of them since Abu Klea.’
‘I have not been able to backtrack at night and look for them. We have been on the move continuously.’
Mayne looked around. ‘There might be others hiding here in these ruins, people who have made it across from the city.’ He remembered Shaytan telling him that on the way out from Khartoum on the steamer, he had spotted figures along the banks of the Nile, scarcely human forms with distended bellies and bulbous eyes crawling over the mud and catching fish with their bare hands, eating them raw.
‘When you have gone across the river, I’ll look around. If there is anyone here, I will find them.’ Charrière handed him a cut section of reed and pointed to the hollow inside where he had pushed out the pith. ‘If you are shot at while you are on the river, you can drop over the side and breathe through this. Bullets are stopped after only a few feet underwater. You will be safe.’
