'It's a play on words,' said Carrot.

There was a long, embarrassed silence.

'Um. I chipped in a few dollars each from you new recruits,' he added, blushing. 'I mean . . . you can pay me back when you like. If you want to. I mean . . . you'd be bound to be friends. Once you got to know him.'

The rest of the Watch exchanged glances.

He could lead armies, Angua thought. He really could. Some people have inspired whole countries to great deeds because of the power of their vision. And so could he. Not because he dreams about marching hordes, or world domination, or an empire of a thousand years. Just because he thinks that everyone's really decent underneath and would get along just fine if only they made the effort, and he believes that so strongly it burns like a flame which is bigger than he is. He's got a dream and we're all part of it, so that it shapes the world around him. And the weird thing is that no-one wants to disappoint him. It'd be like kicking the biggest puppy in the universe. It's a kind of magic.

'The gold's rubbing off,' said Cuddy. 'But it's a good watch,' he added quickly.

'I was hoping we could give it to him tonight,' said Carrot. 'And all go out for a . . . drink . . .'

'Not a good idea,' said Angua.

'Leave it until tomorrow,' said Colon. 'We'll form a guard of honour at the wedding. That's traditional. Everyone holds their swords up in a kind of arch.'

'We've only got one sword between us,' said Carrot glumly.

They all stared at the floor.

'It's not fair,' said Angua. 'I don't care who stole whatever they stole from the Assassins, but he was right to try to find out who killed Mr Hammerhock And no-one cares about Lettice Knibbs.'

'I like to find out who shoot me,' said Detritus.

'Beats me why anyone'd be daft enough to steal from the Assassins,' said Carrot. 'That's what Captain Vimes said. He said you'd have to be a fool to think of breaking into that place.'

They stared at the floor again.

'Like a clown or a jester?' said Detritus.

'Detritus, he didn't mean a cap-and-bells Fool,' said Carrot, in a kindly voice. 'He just meant you'd have to be some sort of idi—'

He stopped. He stared at the ceiling.

'Oh, my,' he said. 'It's as simple as that?'

'Simple as what?' said Angua.

Someone hammered at the door. It wasn't a polite knock. It was the thumping of someone who was either going to have the door opened for them or break it down.

A guard stumbled into the room. Half his armour was off and he had a black eye, but he was just recognizable as Skully Muldoon of the Day Watch.

Colon helped him up.

'Been in a fight, Skully?'

Skully looked up at Detritus, and whimpered.

'The buggers attacked the Watch House!'

'Who?'

'Them!'

Carrot patted him on the shoulder.

'This isn't a troll,' he said. 'This is Lance-Constable Detritus – don't salute. Trolls attacked the Day Watch?'
