Feet of Clay (Discworld 19)

'You're probably right,' said Angua. 'But you can see the size of the place. I bet we wouldn't be able to prove it'd stepped out for half an hour. I think I'll suggest that we put it under what Commander Vimes calls special surveillance.'

'What, like... plain clothes?'

'Something like that,' said Angua carefully.

'Funny to see a pet goat in a slaughterhouse, I thought,' said Cheery, as they walked on through the fog.

'What? Oh, you mean the yudasgoat,' said Angua. 'Most slaughterhouses have one. It's not a pet. I suppose you could call it an employee.'

'Employee? What kind of job could it possibly do?'

'Hah. Walk into the slaughterhouse every day. That's its job. Look, you've got a pen full of frightened animals, right? And they're milling around and leaderless... and there's this ramp into this building, looks very scary... and, hey, there's this goat, it's not scared, and so the flock follows it and' - Angua made a throat-slitting noise - 'only the goat walks out.'

'That's horrible!'

'I suppose it makes sense from the goat's point of view. At least it does walk out,' said Angua.

'How did you know about this?'

'Oh, you pick up all sorts of odds and ends of stuff in the Watch.'

'I've got a lot to learn, I can see,' said Cheery. 'I never thought you had to carry bits of blanket, for a start!'

'It's special equipment if you're dealing with the undead.'

'Well, I knew about garlic and vampires. Anything holy works on vampires. What else works on werewolves?'

'Sorry?' said Angua, who was still thinking about the golem.

'I've got a silver mail vest which I promised my family I'd wear, but is anything else good for werewolves?'

'A gin and tonic's always welcome,' said Angua distantly.

'Angua?'

'Hmm? Yes? What?'

'Someone told me there was a werewolf in the Watchl I can't believe that!'

Angua stopped and stared down at her.

'I mean, sooner or later the wolf comes through,' said Cheery. 'I'm surprised Commander Vimes allows it.'

'There is a werewolf in the Watch, yes,' said Angua.

'I knew there was something odd about Constable Visit.'

Angua's jaw dropped.

'He always looks hungry,' said Cheery. 'And he's got that odd smile all the time. I know a werewolf when I see one.'

'He does look a bit hungry, that's true,' said Angua. She couldn't think of anything else to say.

'Well, I'm going to be keeping my distance!'

'Fine,' said Angua.

'Angua...'
