Work was ending for the day and lines of exhausted, silent slaves, shackled together at the ankle, were shuffling beside the road in the twilight. The clank of their chains against the stones and the flick of the overseer’s whip across their backs were the only sounds. She had heard about such wretches, crammed into the prison blocks attached to the larger farms and worked to death within a year or two: she had never actually seen them close-up. Occasionally a slave found the energy to raise his eyes from the dirt and meet her glance; it was like staring through a hole into hell.
And yet she would not give in, even as nightfall emptied the road of traffic and the line of the aqueduct became harder to follow. The reassuring sight of the villas on the lower slopes of the mountain gradually dissolved, to be replaced by isolated points of torchlight and lamplight, winking in the darkness. Her horse slowed to a walk and she swayed in the saddle in time with its plodding motion.
It was hot. She was thirsty. (Naturally, she had forgotten to bring any water: that was something the slaves always carried for her.) She was sore where her clothes chafed against her sweating skin. Only the thought of the aquarius and the danger he was in kept her moving. Perhaps she would be too late? Perhaps he had been murdered already? She was just beginning to wonder whether she would ever catch up with him when the heavy air seemed to turn solid and to hum around her, and an instant later, from deep inside the mountain to her left, came a loud crack. Her horse reared, pitching her backward, and she was almost thrown, the reins snapping through her sweaty fingers, her damp legs failing to grip its heaving sides. When it plunged forward again and set off at a gallop she only saved herself by wrapping her fingers tightly in its thick mane and clinging for her life.
It must have charged for a mile or more and when at last it began to slow and she was able to raise her head she found that they had left the road and were cantering over open ground. She could hear water somewhere near and the horse must have heard it, too, or smelled it, because it turned and began walking toward the sound. Her cheek had been pressed close to the horse’s neck, her eyes shut tight, but now, as she raised her head, she could make out white heaps of stone and a low brick wall that seemed to enclose an enormous well. The horse bent to drink. She whispered to it, and gently, so as not to alarm it, dismounted. She was trembling with shock.
Her feet sank into mud. Far in the distance she could see the lights of camp fires.
Attilius’s first objective was to remove the debris from underground: no easy task. The tunnel was only wide enough for one man at a time to confront the obstruction, to swing a pickax and dig with a shovel, and once a basket was filled it had to be passed along the matrix from hand to hand until it reached the bottom of the inspection shaft, then attached to a rope and hauled to the surface, emptied, and sent back again, by which time a second basket had already been loaded and dispatched on its way.
Attilius, as he always did, had taken the first turn with the pick. He tore a strip from his tunic and tied it round his mouth and nose to try to reduce the smell of the sulfur. Hacking away at the brick and earth and then shoveling it into the basket was bad enough. But trying to wield the ax in the cramped space and still find the force to smash the concrete into manageable lumps was a labor fit for Hercules. Some of the fragments took two men to carry and before long he had scraped his elbows raw against the walls of the tunnel. As for the heat, compounded by the sweltering night, the sweating bodies, and the burning torches—that was worse than he imagined it could be even in the gold mines of Hispania. But still, Attilius had a sense of progress, and that gave him extra strength. He had found the spot where the Augusta was choked. All his problems would be overcome if he could clear what lay ahead of him.
After a while, Brebix tapped him on the shoulder and offered to take over. Attilius gratefully handed him the pick and watched in admiration as the big man, despite the fact that his bulk completely filled the tunnel, swung it as easily as if it were a toy. The engineer squeezed back along the line and the others shifted to make room for him. They were working as a team now, like a single body: the Roman way again. And whether it was the restorative effects of their bathe, or relief at having a specific task to occupy their thoughts, the mood of the men appeared transformed. He began to think that perhaps they were not such bad fellows after all. You could say what you liked about Ampliatus: at least he knew how to train a slave gang. He took the heavy basket from the man beside him—the same man, he noticed, whose wine he had kicked away—turned, and shuffled with it to the next in the line.
Gradually he lost track of time, his world restricted to this narrow few feet of tunnel, his sensations to the ache of his arms and back, the cuts on his hands from the sharp debris, the pain of his skinned elbows, the suffocating heat. He was so absorbed that at first he did not hear Brebix shouting to him.
“Aquarius!Aquarius! ”
“Yes?” He flattened himself against the wall and edged past the men, aware for the first time that the water in the tunnel was up to his ankles. “What is it?”
“Look for yourself.” Attilius took a torch from the man behind him and held it up close to the compacted mass of the blockage. At first glance it looked solid enough, but then he saw that it was seeping water everywhere. Tiny rivulets were running down the oozing bulk, as if it had broken into a sweat. “See what I mean?” Brebix prodded it with the ax. “If this lot goes, we’ll be drowned like rats in a sewer.”
Attilius was aware of the silence behind him. The slaves had all stopped work and were listening. Looking back he saw that they had already cleared four or five yards of debris. So what was left to hold back the weight of the Augusta? A few feet? He did not want to stop. But he did not want to kill them all, either.
“All right,” he said, reluctantly. “Clear the tunnel.”
They needed no second telling, leaning the torches up against the walls, dropping their tools and baskets and lining up for the rope. No sooner had one man climbed it, his feet disappearing into the inspection shaft, than another had it in his hands and was hauling himself to safety. Attilius followed Brebix up the tunnel and by the time they reached the manhole they were the only ones left belowground.
Brebix offered him the rope. Attilius refused it. “No. You go. I’ll stay down and see what else can be done.” He realized Brebix was looking at him as if he were mad. “I’ll fasten the rope around me for safety. When you get to the top, untie it from the wagon and pay out enough for me to reach the end of the tunnel. Keep a firm hold.”
Brebix shrugged. “Your choice.”
As he turned to climb, Attilius caught his arm. “You are strong enough to hold me, Brebix?”
The gladiator grinned briefly. “You—and your fucking mother!”
Despite his weight, Brebix ascended the rope as nimbly as a monkey, and then Attilius was alone. As he knotted the rope around his waist for a second time he thought that perhaps hewas mad, but there seemed no alternative, for until the tunnel was drained they could not repair it, and he did not have the time to wait for all the water to seep through the obstruction. He tugged on the rope. “All right, Brebix?”
