Guards! Guards! (Discworld 8)

He selected an identical-looking but presumably less lucky arrow and nocked it. Then he looked around the rooftops with a speculative eye.

“Better get my hand in,” he muttered. “Of course, once you learn you never forget, it's like riding a- riding a-riding something you never forget being able to ride.”

He pulled the bowstring back to his ear, and grunted.

“Right,” he wheezed, as his arm trembled with the tension like a branch in a gale. “See the roof of the Assassins' Guild over there?” They peered through the grubby air.

“Right, then,” said Colon. “And do you see the weathervane on it? Do you see it?”

Carrot glanced at the arrowhead. It was weaving back and forth in a series of figure-eights.

“It's a long way off, Sarge,” said Nobby doubtfully.

“Never you mind me, you keep your eyes on the weathervane,” groaned the sergeant.

They nodded. The weathervane was in the shape of a creeping man with a big cloak; his outstretched dagger was always turned to stab the wind. At this distance, though, it was tiny.

“Okay,” panted Colon. “Now, d'you see the man's eye?”

“Oh, come on, ” said Nobby.

“Shutup, shutup, shutup!” groaned Colon. “Do you see it, I said!”

“I think I can see it, Sarge,” said Carrot loyally.

“Right. Right,” said the sergeant, swaying backwards and forwards with effort. “Right. Good lad. Okay. Now keep an eye on it, right?”

He grunted, and loosed the arrow.

Several things happened so fast that they will have to be recounted in stop-motion prose. Probably the first was the bowstring slapping into the soft inner part of Colon's wrist, causing him to scream and drop the bow. This had no effect on the path of the arrow, which was already flying straight and true towards a gargoyle on the rooftop just across the road. It hit it on the ear, bounced, ricocheted off a wall six feet away, and headed back towards Colon apparently at a slightly increased speed, going past his ear with a silky humming noise.

It vanished in the direction of the city walls.

After a while Nobby coughed and gave Carrot a look of innocent inquiry.

“About how big,” he said, “is a dragon's voonerables, roughly?”

“Oh, it can be a tiny spot,” said Carrot helpfully.

“I was sort of afraid of that,” said Nobby. He wandered to the edge of the roof, and pointed downwards. “There's a pond just here,” he said. “They use it for cooling water in the stills. I reckon it's pretty deep, so after the sergeant has shot at the dragon we can jump in it. What d'you say?”

“Oh, but we don't need to do that,” said Carrot. “Because the sergeant's lucky arrow would of hit the spot and the dragon'll be dead, so we won't have anything to worry about.”

“Granted, granted,” said Nobby hurriedly, looking at Colon's scowling face. “But just in case, you know, if by a million-to-one chance he misses-I'm not saying he will, mark you, you just have to think of all eventualities-if, by incredible bad luck, he doesn't quite manage to hit the voonerable dead on, then your dragon is going to lose his rag, right, and it's probably a good idea to not be here. It's a long shot, I know. Call me a worry-wart if you like. That's all I'm saying.”

Sergeant Colon adjusted his armour haughtily.

“When you really need them the most,” he said, “million-to-one chances always crop up. Well-known fact.”

“The sergeant is right, Nobby,” said Carrot virtuously. “You know that when there's just one chance which might just work-well, it works. Otherwise there'd be no-” he lowered his voice-“I mean, it stands to reason, if last desperate chances didn't work, there'd be no ... well, the gods wouldn't let it be any other way. They wouldn't.”

As one man, the three of them turned and looked through the murky air towards the hub of the Disc-world, thousands of miles away. Now the air was grey with old smoke and mist shreds, but on a clear day it was possible to see Cori Celesti, home of the gods. Site of the home of the gods, anyway. They lived in Dunmanifestin, the stuccoed Valhalla, where the gods faced eternity with the kind of minds that were at a loss to know what to do to pass a wet afternoon. They played games with the fates of men, it was said. Exactly what game they thought they were playing at the moment was anyone's guess.

But of course there were rules. Everyone knew there were rules. They just had to hope like Hell that the gods knew the rules, too.

“It's got to work,” mumbled Colon. “I'll be using my lucky arrow 'n all. You're right. Last hopeless chances have got to work. Nothing makes any sense otherwise. You might as well not be alive.”

Nobby looked down at the pond again. After a moment's hesitation Colon joined him. They had the speculative faces of men who had seen many things, and knew that while you could of course depend on heroes, and kings, and ultimately on gods, you could really depend on gravity and deep water.
