Early in the morning, before there was a stir in the house, Will packed his bag and tucked the cloth map Uncle Tam had given him into the top of his boot. He checked that the node stones and light orb were in his pockets, then went over to Cal and shook him awake.
'I'm off,' Will said in a low voice as his brother's eyes flickered open. Cal sat up, scratching his head.
'Thanks for everything, Cal,' Will whispered, 'and say good-bye to Granny for me, won't you?'
'Course I will,' his brother replied, then frowned. 'You know I'd give anything to come, too.'
'I know, I know… but you heard what Tam said: I have a better chance by myself. Anyway, your family is here,' he said finally, and turned to the door.
Will tiptoed down the stairs. He felt exhilarated to be on the move again, but this was tempered by an unexpected pang of sadness that he was leaving. Of course, he could stay here, somewhere where he actually belonged, if he chose, rather than venturing out into the unknown and risking it all. It would be so easy just to go back to bed. As he reached the hallway, he could hear Bartleby snoring somewhere in the shadows. It was a comforting sound, the sound of home. He would never hear that sound again if he went now. He stood by the front door and hesitated. No! How could he ever live with himself if he chose to leave Chester to the Styx? He would rather die trying to free him. He took a deep breath and, glancing behind him into the still house, slipped the heavy catch on the door. He opened it, stepped over the threshold, and then closed it gently behind him. He was out.
He knew he had a considerable distance to cover, so he walked quickly, his bag thumping a rhythm on his back. It took him a little under forty minutes to reach the building at the edge of the cavern that Tam had described. There was no mistaking it as, unlike most structures in the Colony, it had a tiled rather than a stone roof.
He was now on the road that led to the Skull Gate. Tam had said that he had to keep his wits about him because the Styx changed sentries at random intervals, and there was no way of knowing whether one was just about to appear around the corner.
Leaving the road, Will climbed over a gate and sprinted through the yard that lay in front of the building, a ramshackle farm property. He heard a pig-like grunting coming from one of the outlying buildings and spotted some chickens penned up in another area. They were spindly and malnourished but had perfectly white feathers.
He entered the building with the tiled roof and saw the old timber beams leaning against the wall just as Tam had described. As he crept in under them, something moved toward him.
'What—'
It was Tam. He immediately silenced Will by putting a finger to his lips. Will could hardly contain his surprise. He looked at Tam questioningly, but the man's face was grim and unsmiling.
There was hardly enough room for both of them under the beams, and Tam squatted awkwardly as he slid a massive paving slab along the wall. Then he leaned in toward Will.
'Good luck,' he whispered in his ear, and literally pushed him into the jagged opening. Then the slab grated shut behind Will, and he was on his own.
In the pitch-darkness he fumbled in his pocket for the light orb, to which he'd already attached a length of thick string. He knotted this around his neck, leaving his hands free. At first, he moved along the passage with ease, but then, after about thirty feet, it pinched down to a crawlway. The roof of the tunnel was so low that he ended up on his hands and knees. The passage angled upward, and as he heaved himself painfully over jagged plates of broken rock, his backpack kept snagging on the roof.
He caught sight of a movement in front of him and froze on the spot. With some trepidation he lifted the light orb to see what it was. He held his breath as something white flashed across the passage and then landed with a soft thump no more than five feet ahead of him. It was an eyeless rat the size of a well-fed kitten, with snowy fur and whiskers that oscillated like butterfly wings. It stood up on its hind legs, its muzzle twitching and its large, glistening incisors in full view. It showed absolutely no sign that it was afraid of him.
Will found a stone on the tunnel floor and threw it as hard as he could. It missed, glancing off the wall next to the animal, which didn't even flinch. Will's indignation that a mere rat was holding him up welled over, and he lunged toward the animal with a growl. In a single effortless bound it leaped at him, landing smack on his shoulder, and for a split second neither boy nor rat moved. Will felt its whiskers, as delicate as eyelashes, brush his cheek. He shook his shoulders frantically and it launched itself off, springing once on the back of Will's leg as it sped away in the opposite direction.
Will spat a few choice curses at the retreating rodent, then took a deep breath to steady his nerves before setting off again.
He crawled for what seemed like hours, his hands becoming cut and tender from the razor-sharp shards strewn across the floor. Much to his relief, the passage increased in height, and he was almost able to stand up again. Now that he could move at full speed, he became almost euphoric, and felt an irrepressible urge to sing as he negotiated the bends in the tunnel. But he thought better of it when it occurred to him that the sentries at the Skull Gate probably weren't very far from his current position and might somehow be able to hear him.
Eventually he reached the end of the passage, which was cloaked with several layers of stiff sacking, dirtied up to camouflage them against the stone. He brushed them aside and drew his breath as he saw that the tunnel had come out just under the roof of a cavern, and that there was nearly a one-hundred foot drop to the road below. He was proud that he'd gotten this far, past the Skull Gate, but he felt certain that this couldn't be right. He was at such a dizzying height that he immediately assumed he must be in the wrong place. Then Tam's words came back to him:
He leaned over to scan the array of ledges and nooks in the rock wall below him. Then he cautiously clambered out over the edge of the tunnel lip and began the descent, checking and rechecking each skaking hand— and foothold before he made the next move.
He'd climbed no more than twenty feet when he heard a noise below. A desolate groan. He held still and listened, his heart thudding in his ears. It came again. He had one foot on a small ridge with the other dangling in midair, while his hands gripped an outcrop of rock at chest height. He slowly twisted his head and peered down over his shoulder.
Swinging a lantern, a man was strolling in the direction of the Skull Gate with two emaciated cows a couple of paces in front of him. He shouted something at them as he drove them along, completely unaware of Will's presence above him.
Will was totally exposed, by there was nothing he could do. He held absolutely still, praying that the man wouldn't stop and look up. Then just the thing Will was dreading happened: The man came to an abrupt halt.
With his bird's eye view, Will could clearly make out the man's shiny white scalp as he took something out of a shoulder bagg. It was a clay pipe with a long stem, which he loaded with tobacco from a pouch and lit, puffing out little clouds of smoke. Will heard him say something to the cows, and then he started on his way again.
Will breathed a silent sigh of relief and, checking that the coast was clear, quickly finished the descent, crisscrossing from ledge to ledge until he was safely back on the ground. Then he dashed as fast as he could along the road, on either side of which were fields of impossibly proportioned mushrooms, their bulbous, ovoid caps standing on thick stalks. He now recognized these as pennybuns and, as he went, the motion of his light bobbing around his neck threw a multitude of their shifting shadows over the cavern walls behind them.
Will slowed his pace as he developed a painful stitch in his side. He took a series of deep breaths to try to ease it, then forced himself to speed up again, aware that every second counted if he was going to reach Chester in time. Cavern after cavern fell behind him, the fields of pennybuns eventually gave way to black carpets of lichen, and he was relieved when he spotted the first of the lampposts and the hazy outline of a building in the distance. He was getting closer. Suddenly, he found himself at a huge stone archway hewn into the rock. He went through it, into the main body of the Quarter. Soon the dwellings were crowding the sides of the road, and he was becoming more and more nervous. Although nobody seemed to be around, he kept the sound from his boots to a minimum by running on his toes. He was terrified that someone was going to appear from one of the houses and spot him. Then he saw what he'd been looking for. It was the first of the side tunnels that Tam had mentioned.
'Left, left, right.' As he went, Will repeated the sequence Tam had drummed into him.
The tunnels were just wide enough for a coach to pass through them.
