'It's one of the abbot's words. It means more numbers than you can imagine in a yonk.'
'What's a yonk?'
'A very long time.'
'And we don't feel it? The universe is destroyed and we don't feel it?'
'They say not. The first time it was explained to me I got a bit jumpy, but it's far too quick for us to notice.' Lobsang stared at the snow for a while. Then he said, 'All right. Go on.'
'Someone in Uberwald built this clock out of glass. Powered by lightning, as I recall. It somehow got down to a level where it could tick with the universe.'
'Why did he want to do that?'
'Listen, he lived in a big old castle on a crag in Uberwald. People like that don't need a reason apart from “because I can”. They have a nightmare and try to make it happen.'
'But, look, you can't make a clock like that, because it's inside the universe, so it'll ... get rebuilt when the universe does, right?' Lu-Tze looked impressed, and said so. 'I'm impressed,' he said. 'It'd be like opening a box with the crowbar that's inside.'
'The abbot believes that part of the clock was outside, though.'
'You can't have something outside the-'
'Tell that to a man who has been working on the problem for nine lifetimes,' said Lu-Tze. 'You want to hear the rest of the story?'
'Yes, Sweeper.'
'So ... we were spread pretty thin in those days, but there was this young sweeper-'
'You,' said Lobsang. 'This is going to be you, right?'
'Yes, yes,' said Lu-Tze testily. 'I was sent to Uberwald. History hadn't diverged much in those days, and we knew something big was going to happen around Bad Schüschein. I must have spent weeks looking. You know how many remote castles there are along the gorges? You can't move for remote castles!'
'That's why you didn't find the right one in time,' said Lobsang. 'I remember what you told the abbot.'
'I was just down in the valley when the lightning struck the tower,' said Lu-Tze. 'You know it is written, “Big events always cast their shadows.” But I couldn't detect where it was happening until too late. A half-mile sprint uphill faster than a lightning bolt... No one could do that. Nearly made it, though - I was actually through the door when it all went to hell!'
'No point in blaming yourself, then.'
'Yes, but you know how it is - you keep thinking “If only I'd got up earlier, or had gone a different way...”' said Lu-Tze. 'And the clock struck,' said Lobsang. 'No. It stuck. I told you part of it was outside the universe. It wouldn't go with the flow. It was trying to count the tick, not move with it.'
'But the universe is huge! It can't be stopped by a piece of clock work!' Lu-Tze flicked the end of his cigarette into the fire . 'The abbot says the size wouldn't make any difference at all,' he said. 'Look, it's taken him nine lifetimes to know what he knows, so it's not our fault if we can't understand it, is it? History shattered. It was the only thing that could give. Very strange event. There were
cracks left all over the place. The... oh, I can't remember the words... the fastenings that tell bits of the past which bits of the present they belong to, they were flapping allover the place. Some got lost for ever.' Lu-Tze stared into the dying flames. 'We stitched it up as best we could,' he added. 'Up and down history. Filling up holes with bits of time taken from somewhere else. It's a patchwork, really.'
'Didn't people notice?'
'Why should they? Once we'd done it, it had always been like that. You'd be amazed at what we got away with. F'rinstance-'
'I'm sure they'd spot it somehow.' Lu-Tze gave Lobsang one of his sidelong glances. 'Funny you should say that. I've always wondered about it. People say things like “Where did the time go?” and “It seems like only yesterday.” We had to do it, anyway. And it's healed up very nicely.'
'But people would look in the history books and see-'
'Words, lad. That's all. Anyway, people have been messing around with time ever since there were people. Wasting it, killing it, sparing it, making it up. And they do it. People's heads were made to play with time. Just like we do, except we're better trained and have a few extra skills. And we've spent centuries working to bring it all back in line. You watch the Procrastinators even on a quiet day. Moving time, stretching it here, compressing it there... it's a big job. I'm not going to see it smashed a second time. A second time, there won't be enough left to repair.' He stared at the embers. 'Funny thing,' he said. 'Wen himself had some very curious ideas about time, come the finish. You remember I told you that he reckoned time was alive: He said it acted like a living thing, anyway. Very strange ideas indeed. He said he'd met Time, and she was a woman. To him, anyway. Everyone says that was just a very complicated metaphor, and maybe I was simply hit on the head or something, but on that day I looked at the glass clock just as it exploded and-' He stood up and grabbed his broom. 'Best foot forward, lad. Another two or three seconds and we'll be down in Bong Phut.'
'What were you going to say?' said Lobsang, hurrying to his feet. 'Oh, just an old man rambling,' said Lu-Tze. 'The mind wanders a bit when you get to over seven hundred. Let's get moving.'
'Sweeper?'
'Yes, lad?'
