'Puzzling, that,' said Ridcully. 'My dad used to say the Verruca Gnome turned up if you walked around in bare feet but I never knew you existed. I thought he just made it up. I mean, tooth fairies, yes, and them little buggers that live in flowers, used to collect 'em myself as a lad, but can't recall anything about verrucas.' He drank thoughtfully. 'Cot a distant cousin called Verruca, as a matter of fact. It's quite a nice sound, when you come to think of it.'
He looked at the gnome over the top of his glass.
You didn't become Archchancellor without a feeling for subtle wrongness in a situation. Well, that wasn't quite true. It was more accurate to say that you didn't remain Archchancellor for very long.
'Good job, is it?' he said thoughtfully.
'Dandruff'd be better,' said the gnome. 'At least I'd be out in the fresh air.'
'I think we'd better check up on this,' said Ridcully. 'Of course, it might be nothing.'
'Oh, thank you,' said the Verruca Gnome, gloomily.
It was a magnificent Grotto this year, Vernon Crumley told himself. The staff had worked really hard. The Hogfather's sleigh was a work of art in itself, and the pigs looked really real and a wonderful shade of pink.
The Grotto took up nearly all of the first floor. One of the pixies had been Disciplined for smoking behind the Magic Tinkling Waterfall and the clockwork Dolls of All Nations showing how We Could All Get Along were a bit jerky and giving trouble but all in all, he told himself, it was a display to Delight the Hearts of Kiddies everywhere.
The kiddies were queueing up with their parents and watching the display owlishly.
And the money was coming in. Oh, how the money was coming in.
So that the staff would not be Tempted, Mr Crumley had set up an arrangement of overhead wires across the ceilings of the store. In the middle of each floor was a cashier in a little cage. Staff took money from customers, put it in a little clockwork cable car, sent it whizzing overhead to the cashier, who'd make change and start it rattling back again. Thus there was no possibility of Temptation, and the little trolleys were shooting back and forth like fireworks.
Mr Crumley loved Hogswatch. It was for. the Kiddies, after all.
He tucked his fingers in the pockets of his waistcoat and beamed.
'Everything going well, Miss Harding?'
'Yes, Mr Crumley,' said the cashier, meekly.
'Jolly good.' He looked at the pile of coins.
A bright little zig-zag crackled off them and earthed itself on the metal grille.
Mr Crumley blinked. In front of him sparks flashed off the steel rims of Miss Harding's spectacles.
The Grotto display changed. For just a fraction of a second Mr Crumley had the sensation of speed, as though what appeared had screeched to a halt. Which was ridiculous.
The four pink papier-mache pigs exploded. A cardboard snout bounced off Mr Crumley's head.
There, sweating and grunting in the place where the little piggies had been, were ... well, he assumed they were pigs, because hippopotamuses didn't have pointy ears and rings through their noses. But the creatures were huge and grey and bristly and a cloud of acrid mist hung over each one.
And they didn't look sweet. There was nothing charming about them. One turned to look at him with small, red eyes, and didn't go 'oink', which was the sound that Mr Crumley, born and raised in the city, had always associated with pigs.
It went 'Ghnaaarrrwnnkh?'
The sleigh had changed, too. He'd been very pleased with that sleigh. It had delicate silver curly bits on it. He'd personally supervised the gluing on of every twinkling star. But the splendour of it was lying in glittering shards around a sledge that looked as though it had been built of crudely sawn tree trunks laid on two massive wooden runners. It looked ancient and there were faces carved on the wood, nasty crude grinning faces that looked quite out of place.
Parents were yelling and trying to pull their children away, but they weren't having much luck. The children were gravitating towards it like flies to jam.
Mr Crumley ran towards the terrible thing, waving his hands.
'Stop that! Stop that!' he screamed. 'You'll frighten the Kiddies!'
He heard a small boy behind him say, 'They 've got tusks! Cool!'
His sister said, 'Hey, look, that one's doing a wee!' A tremendous cloud of yellow steam arose. 'Look, it's going all the way to the stairs! All those who can't swim hold onto the banisters!'
'They eat you if you're bad, you know,' said a small girl with obvious approval. 'All up. Even the bones. They crunch them.'
Another, older, child opined: 'Don't be childish. They're not real. They've just got a wizard in to do the magic. Or it's all done by clockwork. Everyone knows they're not really r...'
One of the boars turned to look at him. The boy moved behind his mother.
