Corporal Carrot, Ankh-Morpork City Guard (Night Watch), sat down in his nightshirt, took up his pencil, sucked the end for a moment, and then wrote:

“Dearest Mume and Dad,

Well here is another fine Turnup for the Books, for I have been made Corporal!! It means another Five Dollars a month plus also I have a new jerkin with, two stripes upon it as well. And a new copper badge! It is a Great responsibility!! This is all because we have got new recruits because the Patrician who, as I have formerly vouchsafed is the ruler of the city, has agreed the Watch must reflect the ethnic makeup of the City—”

Carrot paused for a moment and stared out of the small dusty bedroom window at the early evening sunlight sidling across the river. Then he bent over the paper again.

“—which I do not Fulley understand but must have something to do with the dwarf Grabpot Thundergust's Cosmetic Factory. Also, Captain Vimes of who I have often written to you of is, leaving the Watch to get married and Become a Fine Gentleman and, I'm sure we wish him All the Best, he taught me All I Know apart, from the things I taught myself. We are clubbing together to get him a Surprise Present, I thought one of those new Watches that don't need demons to make them go and we could inscribe on the back something like ‘A Watch from, your Old Freinds in the Watch’, this is a pune or Play on Words. We do not know who will be the new Captain, Sgt Colon says he will Resign if it's him, Cpl Nobbs—”

Carrot stared out of the window again. His big honest forehead wrinkled with effort as he tried to think of something positive to say about Corporal Nobbs.

“—is more suited in his current Roll, and I have not been in the Watch long enough. So we shall just have to wait and See—”

It began, as many things do, with a death. And a burial, on a spring morning, with mist on the ground so thick that it poured into the grave and the coffin was lowered into cloud.

A small greyish mongrel, host to so many assorted doggy diseases that it was surrounded by a cloud of dust, watched impassively from the mound of earth.

Various elderly female relatives cried. But Edward d'Eath didn't cry, for three reasons. He was the eldest son, the thirty-seventh Lord d'Eath, and it was Not Done for a d'Eath to cry; he was—just, the diploma still had the crackle in it—an Assassin, and Assassins didn't cry at a death, otherwise they'd never be stopping; and he was angry. In fact, he was enraged.

Enraged at having to borrow money for this poor funeral. Enraged at the weather, at this common cemetery, at the way the background noise of the city didn't change in any way, even on such an occasion as this. Enraged at history. It was never meant to be like this.

It shouldn't have been like this.

He looked across the river to the brooding bulk of the Palace, and his anger screwed itself up and became a lens.

Edward had been sent to the Assassins' Guild because they had the best school for those whose social rank is rather higher than their intelligence. If he'd been trained as a Fool, he'd have invented satire and made dangerous jokes about the Patrician. If he'd been trained as a Thief,1 he'd have broken into the Palace and stolen something very valuable from the Patrician.

However… he'd been sent to the Assassins…

That afternoon he sold what remained of the d'Eath estates, and enrolled again at the Guild school.

For the post-graduate course.

He got full marks, the first person in the history of the Guild ever to do so. His seniors described him as a man to watch—and, because there was something about him that made even Assassins uneasy, preferably from a long way away.

In the cemetery the solitary gravedigger filled in the hole that was the last resting place of d'Eath senior.

He became aware of what seemed to be thoughts in his head. They went something like this:

Any chance of a bone? No, no, sorry, bad taste there, forget I mentioned it. You've got beef sandwiches in your wossname, lunchbox thingy, though. Why not give one to the nice little doggy over there?

The man leaned on his shovel and looked around.

The grey mongrel was watching him intently.

It said, “Woof?”

It took Edward d'Eath five months to find what he was looking for. The search was hampered by the fact that he did not know what he was looking for, only that he'd know it when he found it. Edward was a great believer in Destiny. Such people often are.

The Guild library was one of the largest in the city. In certain specialized areas it was the largest. These areas mainly had to do with the regrettable brevity of human life and the means of bringing it about.

Edward spent a lot of time there, often at the top of a ladder, often surrounded by dust.

He read every known work on armaments. He didn't know what he was looking for and he found it in a note in the margin of an otherwise very dull and inaccurate treatise on the ballistics of crossbows. He copied it out, carefully.

Edward spent a lot of time among history books as well. The Assassins' Guild was an association of gentlemen of breeding, and people like that regard the whole of recorded history as a kind of stock book. There were a great many books in the Guild library, and a whole portrait gallery of kings and queens,2 and Edward d'Eath came to know their aristocratic faces better than he did his own. He spent his lunch hours there.

It was said later that he came under bad influences at this stage. But the secret of the history of Edward d'Eath was that he came under no outside influences at all, unless you count all those dead kings. He just came under the influence of himself.

That's where people get it wrong. Individuals aren't naturally paid-up members of the human race, except biologically. They need to be bounced around by the Brownian motion of society, which is a mechanism by which human beings constantly remind one another that they are… well… human beings. He was also spiralling inwards, as tends to happen in cases like this.

He'd had no plan. He'd just retreated, as people do when they feel under attack, to a more defensible position, i.e. the past, and then something happened which had the same effect on Edward as finding a plesiosaur in his goldfish pond would on a student of ancient reptiles.

He'd stepped out blinking in the sunlight one hot afternoon, after a day spent in the company of departed glory, and had seen the face of the past strolling by, nodding amiably to people.

He hadn't been able to control himself. He'd said, “Hey, you! Who are y-ou?”

The past had said, “Corporal Carrot, sir. Night Watch. Mr d'Eath, isn't it? Can I help you?”

“What? No! No. Be about your b-usiness!”

The past nodded and smiled at him, and strolled on, into the future.
