Billy looked up.

'It's not in my hands,' he said, very simply. 'Not now. It's up to Grandfather. He may be merciful; he may not.'

'Why do you have to tell him?'

'He knows what's in me. He and I... we're like one. That's how I know he wouldn't cheat me.'

Soon it would be night; the lights would go out along the wing, the shadows would come.

'So I just have to wait, do I?' Cleve said.

Billy nodded. 'I'll call him, and then we'll see.'

Call him?, Cleve thought. Did the old man need summoning from his resting place every night? Was that what he had seen Billy doing, standing in the middle of the cell, eyes closed and face up to the window? If so, perhaps the boy could be prevented from putting in his call to the dead.

As the evening deepened Cleve lay on his bunk and thought his options through. Was it better to wait here, and see what judgement came from Tait, or attempt to take control of the situation and block the old man's arrival? If he did so, there would be no going back; no room for pleas or apologies: his aggression would undoubtedly breed aggression. If he failed to prevent the boy from calling Tait, it would be the end.

The lights went out. In cells up and down the five landings of B Wing men would be turning their faces to their pillows. Some, perhaps, would lie awake planning their careers when this minor hiccup in their professional lives was over; others would be in the arms of invisible mistresses. Cleve listened to the sounds of the cell: the rattling progress of water in the pipes, the shallow breathing from the bunk below. Sometimes it seemed that he had lived a second lifetime on this stale pillow, marooned in darkness.

The breathing from below soon became practically inaudible; nor was there sound of movement. Perhaps Billy was waiting for Cleve to fall asleep before he made any move. If so, the boy would wait in vain. He would not close his eyes and leave them to slaughter him in his sleep. He wasn't a pig, to be taken uncomplaining to the knife.

Moving as cautiously as possible, so as to arouse no suspicion, Cleve unbuckled his belt and pulled it through the loops of his trousers. He might make a more adequate binding by tearing up his sheet and pillowcase, but he could not do so without arousing Billy's attention. Now he waited, belt in hand, and pretended sleep.

Tonight he was grateful that the noise in the Wing kept stirring him from dozing, because it was fully two hours before Billy moved out of his bunk, two hours in which - despite his fear of what would happen should he sleep - Cleve's eyelids betrayed him on three or four occasions. But others on the landings were tearful tonight; the deaths of Lovell and Nayler had made even the toughest cons jittery. Shouts - and countercalls from those woken - punctuated the hours. Despite the fatigue in his limbs, sleep did not master him.

When Billy finally go up from the lower bunk it was well past twelve, and the landing was all but quiet. Cleve could hear the boy's breath; it was no longer even, but had a catch in it. He watched, eyes like slits, as Billy crossed the cell to his familiar place in front of the window. There was no doubt that he was about to call up the old man.

As Billy closed his eyes, Cleve sat up, threw off his blanket and slipped down from the bunk. The boy was slow to respond. Before he quite comprehended what was happening, Cleve had crossed the cell, and thrust him back against the wall, hand clamped over Billy's mouth.

'No, you don't,' he hissed, 'I'm not going to go like Lowell.' Billy struggled, but Cleve was easily his physical superior.

'He's not going to come tonight,' Cleve said, staring into the boy's wide eyes, 'because you're not going to call him.'

Billy fought more violently to be free, biting hard against his captor's palm. Cleve instinctively removed his hand and in two strides the boy was at the window, reaching up. In his throat, a strange half-song; on his face, sudden and inexplicable tears. Cleve dragged him away.

'Shut your noise up!' he snapped. But the boy continued to make the sound. Cleve hit him, open-handed but hard, across the face. 'Shut up!' he said. Still the boy refused to cease his singing; now the music had taken on another rhythm. Again, Cleve hit him; and again. But the assault failed to silence him. There was a whisper of change in the air of the cell; a shifting in its chiaroscuro. The shadows were moving.

Panic took Cleve. Without warning he made a fist and punched the boy hard in the stomach. As Billy doubled up an upper-cut caught his jaw. It drove his head back against the wall, his skull connecting with the brick. Billy's legs gave, and he collapsed. A featherweight, Cleve had once thought, and it was true. Two good punches and the boy was laid out cold.

Cleve glanced round the cell. The movement in the shadows had been arrested; they trembled though, like greyhounds awaiting release. Heart hammering, he carried Billy back to his bunk, and laid . him down. There was no sign of consciousness returning; the boy lay limply on the mattress while Cleve tore up his sheet, and gagged him, thrusting a ball of fabric into the boy's mouth to prevent him making a sound behind his gag. He then preceded to tie Billy to the bunk, using both his own belt and the boy's, supplemented with further makeshift bindings of torn sheets. It took several minutes to finish the job. As Cleve was lashing the boy's legs together, he began to stir. His eyes flickered open, full of puzzlement. Then, realizing his situation, he began to thrash his head from side to side; there was little else he could do to signal his protest.

'No, Billy,' Cleve murmured to him, throwing a blanket across his bound body to keep the fact from any officer who might look in through the spy-hole before morning, 'Tonight, you don't bring him. Everything I said was true, boy. He wants out; and he's using you to escape.' Cleve took hold of Billy's head, fingers pressed against his cheeks. 'He's not your friend. / am. Always have been.' Billy tried to shake his head from Cleve's grip, but couldn't. 'Don't waste your energy,' Cleve advised, 'it's going to be a long night.'

He left the boy on the bunk, crossed the cell to the wall, and slid down it to sit on his haunches and watch. He would stay awake until dawn, and then, when there was some light to think by, he'd work out his next move. For now, he was content that his crude tactics had worked.

The boy had stopped trying to fight; he had clearly realised the bonds were too expertly tied to be loosened. A kind of calm descended on the cell: Cleve sitting in the patch of light that fell through the window, the boy lying in the gloom of the lower bunk, breathing steadily through his nostrils. Cleve glanced at his watch. It was twelve-fifty-four. When was morning? He didn't know. Five hours, at least. He put his head back, and stared at the light.

It mesmerised him. The minutes ticked by slowly but steadily, and the light did not change. Sometimes an officer would advance along the landing, and Billy, hearing the footsteps, would begin his struggling afresh. But nobody looked into the cell. The two prisoners were left to their thoughts; Cleve to wonder if there would ever come a time when he could be free of the shadow behind him, Billy to think whatever thoughts came to bound monsters. And still the dead-of-night minutes went, minutes that crept across the mind like dutiful schoolchildren, one upon the heels of the next, and after sixty had passed that sum was called an hour. And dawn was closer by that span, wasn't it? But then so was death, and so, presumably, the end of the world: that glorious Last Trump of which The Bishop had spoken so fondly, when the dead men under the lawn outside would rise as fresh as yesterday's bread and go out to meet their Maker. And sitting there against the wall, listening to Billy's inhalations and exhalations, and watching the light in the glass and through the glass, Cleve knew without doubt that even if he escaped this trap, it was only a temporary respite; that this long night, its minutes, its hours, were a foretaste of a longer vigil. He almost despaired then; felt his soul sink into a hole from which there seemed to be no hope of retrieval. Here was the real world, he wept. Not joy, not light, not looking forward; only this waiting in ignorance, without hope, even of fear, for fear came only to those with dreams to lose. The hole was deep and dim. He peered up out of it at the light through the window, and his thoughts became one wretched round. He forgot the bunk and the boy lying there. He forgot the numbness that had overtaken his legs. He might, given time, have forgotten even the simple act of taking breath, but for the smell of urine that pricked him from his fugue.
