Pyramids (Discworld 7)

'What's that for?' said his father wearily.

'Next week.' The leading accountant glared at the top slab. 'For example,' he said. 'You know Rthur the fresco painter?'

'What about him?'

'He - that is, they - have put in a bill for two years' work.'

'Oh.'

'They said they did it on Tuesday. On account of how time is fractal in nature, they said.'

'They said that?' said Ptaclusp.

'It's amazing what they pick up,' said one of the accountants, glaring at the paracosmic architects.

Ptaclusp hesitated. 'How many of them are there?'

'How should we know? We know there were fifty-three. Then he went critical. We've certainly seen him around a lot.' Two of the IIas sat back and steepled their fingers, always a bad sign in anyone having anything to do with money. 'The problem is,' one of them continued, 'that after the initial enthusiasm a lot of the workers looped themselves unofficially so that they could stay at home and send themselves out to work.'

'But that's ridiculous,' Ptaclusp protested weakly. 'They're not different people, they're just doing it to themselves.'

'That's never stopped anyone, father,' said IIa. 'How many men have stopped drinking themselves stupid at the age of twenty to save a stranger dying of liver failure at forty?'

There was silence while they tried to work this one out.

'A stranger-?' said Ptaclusp uncertainly.

'I mean himself, when older,' snapped IIa. 'That was philosophy,' he added.

'One of the masons beat himself up yesterday,' said one of the IIbs gloomily. 'He was fighting with himself over his wife. Now he's going mad because he doesn't know whether it's an earlier version of him or someone he hasn't been yet. He's afraid he's going to creep up on him. There's worse than that, too. Dad, we're paying forty thousand people, and we're only employing two thousand.'

'It's going to bankrupt us, that's what you're going to say,' said Ptaclusp. 'I know. It's all my fault. I just wanted something to hand on to you, you know. I didn't expect all this. It seemed too easy to start with.'

One of the IIas cleared his throat.

'It's . . . uh . . . not quite as bad as all that,' he said quietly.

'What do you mean?'

The accountant laid a dozen copper coins on the table.

'Well, er,' he said. 'You see, eh, it occurred to me, since there's all this movement in time, that it's not just people who can be looped, and, er, look, you see these coins?'

One coin vanished.

'They're all the same coin, aren't they,' said one of his brothers.

'Well, yes,' said the IIa, very embarrassed, because interfering with the divine flow of money was alien to his personal religion. 'The same coin at five minute intervals.'

'And you're using this trick to pay the men?' said Ptaclusp dully.

'It's not a trick! I give them the money,' said IIa primly. 'What happens to it afterwards isn't my responsibility, is it?'

'I don't like any of this,' said his father.

'Don't worry. It all evens out in the end,' said one of the IIas. 'Everyone gets what's coming to them.'

'Yes. That's what I'm afraid of,' said Ptaclusp.
