I'd say.”
“What else did they do?”
“Well, there's…” Colon racked his brains. “There's al-gebra. That's like sums with letters. For… for people whose brains aren't clever enough for numbers, see?”
“Is that a fact?”
“Right,” said Colon. “In fact,” he went on, a little more assertively now he could see a way ahead, “I heard this wizard down the University say that the Klatchians invented nothing. That was their great contribution to maffs, he said. I said ‘What?’ an' he said, they come up with zero{17}.”
“Dun't sound that clever to me,” said Nobby. “Anyone could invent nothing. I ain't invented anything.”
“My point exactly,” said Colon. “I told him, it was people who invented numbers like four and, and—”
“—seven—”
“—right, who were the geniuses.
“It's having all that desert,” said Nobby.
“Right! Good point. Desert. Which, as everyone knows, is basically nothing. Nothing's a natural resource to them. It stands to reason. Whereas we're more civilized, see, and we got a lot more stuff around to count, so we invented numbers. It's like… well, they say the Klatchians invented astronomy—”
“Al-tronomy,” said Nobby helpfully.
“No, no… no, Nobby, I reckon they'd discovered esses by then, probably nicked 'em off'f us… anyway, they were
“I heard where they've got a lot of odd gods,” said Nobby.
“Yeah,
They watched the painter in silence for a moment. Colon was dreading the question that came.
“So how
“I hope you ain't being
“No, of course not. I was just asking. I can see where they'd be a lot worse than ours, being foreign and everything.”
“And of course they're all mad for fighting,” said Colon. “Vicious buggers with all those curvy swords of theirs.”
“You mean, like they viciously attack you while cowardly running away after tasting cold steel?” said Nobby, who sometimes had a treacherously good memory for detail.
“You can't trust 'em, like I said. And they burp hugely after meals.”
“Well… so do you, sarge.”
“Yes, but I don't pretend it's
“Well, it's certainly a good job there's you around to explain things, sarge,” said Nobby. “It's amazing the stuff you know.”
“I surprise myself, sometimes,” said Colon modestly.
The painter of the ship leaned back to admire his work. They heard him give a heartfelt little groan, and both of them nodded in satisfaction.
Hostage negotiations were always tricky, Carrot had learned. It paid not to rush things. Let the other man talk when he was ready.
So he was whiling away the time sitting behind the upturned cart they were using as a shield from the occasional random arrow and writing his letter home. The exercise was carried out with much frowning, sucking of the pencil and what Commander Vimes called a ballistic approach to spelling and punctuation.
Carrot folded the letter carefully and slipped it under his breastplate.
“I think they have had long enough to consider our suggestion, constable. What's next on the list?”
Constable Shoe leafed through a file of grubby paper and pulled out another sheet.
“Well, we're down to offences of stealing pennies off blind beggars now,” he said. “Oh, no, this is a good one…”
Carrot took the sheet in one hand and megaphone in the other and raised his head carefully over the edge of the cart.
“Good morning again!” he said brightly. “We've found another one. Theft of jewellery from—”
“Yes! Yes! We did it!” shouted a voice from the building.
“Really? I haven't even said what it was yet,” said Carrot.
“Never mind, we
“I think you ought to be able to tell me what you stole,” said Carrot.
“Er… rings? Gold rings?”
“Sorry, no rings mentioned.”
“Pearl necklace? Yes, that's what—”
“Getting warmer, but no.”
“Earrings?”
“Ooo, you're so close,” said Carrot encouragingly.
“A crown, was it? Maybe a coronet?”
Carrot leaned down to the constable. “Says here a tiara, Reg, can we let—?” He stood up. “We're prepared to accept ‘coronet’. Well done!”
He looked down at Constable Shoe again.
“This is all right, isn't it, Reg? It's not coercion, is it?”
“Can't see how it can be, captain. I mean, they broke in, they took a hostage…”
“I suppose you're right—”
“
“Seems to be about it, sir,” said Reg Shoe, peering around the edge of the cart. “We've got them down for everything but the Hide Park Flasher—”
“We did that!” screamed someone.
