'Put a title like "Letters" on the top and put them in,' said William. 'Except the one about the dwarfs. That sounds like Mr Windling. It sounds like my father, too, except that at least he can spell "undesirable" and wouldn't use crayon.'

'Why not that letter?'

'Because it's offensive.'

'Some people think it's true, though,' said Sacharissa. 'There's been a lot of trouble.'

'Yes, but we shouldn't print it.'

William called Goodmountain over and showed him the letter. The dwarf read it.

'Put it in,' he suggested. 'It'll fill a few inches.'

'But people will object,' said William.

'Good. Put their letters in, too.'

Sacharissa sighed. 'We'll probably need them,' she said. 'William, grandfather says no one in the Guild will engrave the iconographs for us.'

'Why not? We can afford the rates.'

'We're not Guild members. It's all getting unpleasant. Will you tell Otto?'

William sighed and walked over to the ladder.

The dwarfs used the cellar as a bedroom, being naturally happier with a floor over their heads. Otto had been allowed to use a dank corner, which he'd made his own by hanging an old sheet across on a rope.

'Oh, hello, Mr Villiam,' he said, pouring something noxious from one bottle into another.

'I'm afraid it looks as if we won't get anyone to engrave your pictures,' said William.

The vampire seemed unmoved by this. 'Yes, I vundered about zat.'

'So I'm sorry to say that--'

'No problem, Mr Villiam. Zere is alvays a yay.'

'How? You can't engrave, can you?'

'No, but... all ve are printing is black and vite, yes? And zer

paper is vite zo all ve are really printink is black, okay? I looked at how zer dvarfs do zer letters, and zey haf all zese bits of metal lying around and... you know how zer engravers can engrave metal viz acid?'

'Yes?'

'Zo, all I haf to do is teach zer imps to paint viz acid. End of problem. Getting grey took a bit of thought, but I zink I haf--'

'You mean you can get the imps to etch the picture straight on to a plate?'

'Yes. It is vun of those ideas that are obvious ven you zink about it.' Otto looked wistful. 'And I zink about light all zer time. All zer... time.'

William vaguely remembered something someone had once said: the only thing more dangerous than a vampire crazed with blood lust was a vampire crazed with anything else. All the meticulous single-mindedness that went into finding young women who slept with their bedroom window open was channelled into some other interest, with merciless and painstaking efficiency.

'Er, why do you need to work in a dark room, though?' he said. 'The imps don't need it, do they?'

'Ah, zis is for my experiment,' said Otto proudly. 'You know zat another term for an iconographer would be "photographer"? From the old word photus in Latation, vhich means--'

' "To prance around like a pillock ordering everyone about as if you owned the place",' said William.

'Ah, you know it!'

William nodded. He'd always wondered about that word.

'Veil, I am vorking on an obscurograph,'

William's forehead wrinkled. It was turning into a long day. Taking pictures with darkness?' he ventured.

'Viz true darkness, to be precise,' said Otto, excitement entering his voice. 'Not just absence of light. Zer light on zer ozzer side of darkness. You could call it... living darkness. Ve can't see it, but imps can. Did you know zer Uberwaldean Deep Cave land eel emits a burst of dark light ven startled?'

William glanced at a large glass jar on the bench. A couple of ugly things were coiled up in the bottom.

'And that will work, will it?'

'I zink so. Hold it vun minute.'

'I really ought to be getting back--'

'Zis vill not take a second

Otto gently lifted one of the eels out of its jar and put it into the hod usually occupied by a salamander. He carefully aimed one of his iconographs at William and nodded.

'Vun... two... three... BOO!'

There was--

--there was a soft noiseless implosion, a very brief sensation of the world being screwed up small, frozen, smashed into tiny little sharp pins and hammered through every cell of William's body.* Then the gloom of the cellar flowed back.

'That was... very strange,' said William, blinking. 'It was like something very cold walking through me.'

'Much may be learnt about dark light now ve have left our disgusting past behind us and haf emerged into zer bright new future vhere ve do not zink about zer b-vord all day in any vay at all,' said Otto,'fiddling with the iconograph. He looked hard at the picture the imp had painted and then glanced up at William. 'Oh veil, back to zer drawink board,' he said.

'Can I see?'

'It vould embarrass me,' said Otto, putting the square of cardboard down on his makeshift bench. 'All zer time I am doing things wronk.'

'Oh, but I'd--'

'Mister de Worde, dere's something happening!'

The bellow came from Rocky, whose head eclipsed the hole.

'What is it?'

'Something at der palace. Someone's been killed!'

William sprang up the ladder. Sacharissa was sitting at her desk, looking pale.

'Someone's assassinated Vetinari?' said William.

'Er, no,' said Sacharissa. 'Not... exactly,'

Down in the cellar Otto Chriek picked up the dark light

* In many ways William de Worde had quite a graphic imagination.

iconograph and looked at it again. Then he scratched it with a long pale finger, as if trying to remove something.

'Strange...' he said.

The imp hadn't imagined it, he knew. Imps had no imagination whatsoever. They didn't know how to lie.

He looked around the bare cellar suspiciously.

'Is zere anyvun zere?' he said. 'Is anyvun playink zer silly buggers?'

Thankfully there was no answer.

Dark light. Oh dear. There were lots of theories about dark light...

'Otto!'

He glanced up, shoving the picture into his pocket.

'Yes, Mr Villiam?'

'Get your stuff together and come with me! Lord Vetinari's murdered someone! Er, it is alleged,' William added. 'And it can't possibly be true.'

It sometimes seemed to William that the whole population of Ankh-Morpork was simply a mob waiting to happen. It was mostly spread thin, like some kind of great amoeba, all across the city. But when something happened somewhere it contracted around that point, like a cell around a piece of food, filling the streets with people.

It was growing around the main gates to the palace. It came together apparently at random. A knot of people would attract other people, and become a bigger, more complicated knot. Carts and sedan chairs would stop to find out what was going on. The invisible beast grew bigger.

There were watchmen on the gate instead of the palace guard. This was a problem. 'Let me in, I'm nosy,' was not a request likely to achieve success. It lacked a certain authority.

'Vy are ve stoppink?' said Otto.

'That's Sergeant Detritus on the gate,' said William.

'Ah. A troll. Very stupid,' opined Otto.

'But hard to fool. I'm afraid I shall have to try the truth.'

'Vy vill zat vork?'

'He's a policeman. The truth usually confuses them. They don't often hear it.'

The big troll sergeant watched William impassively as he approached. It was a proper policeman's stare. It gave nothing away. It said: I can see you, now I'm waiting to see what you're going to do that's wrong.

'Good morning, sergeant,' said William.

A nod from the troll indicated that he was prepared to accept, on available evidence, that it was morning and, in certain circumstances, by some people, it might be considered good.

'I urgently need to see Commander Vimes.'

'Oh, yes?'

'Yes. Indeed.'

'And does he urgently need to see you?' The troll leaned closer. 'You're Mr de Worde, right?'

'Yes. I work for the Times.'

'I don't read dat,' said the troll.

'Really? We'll bring out a large-print edition,' said William.

'Dat was a very funny joke,' said Detritus. Ting is, fick though I am, I am der one that's sayin' you can stay outside, so-- What's dat vampire doing?'

'Hold it just vun second!' said Otto.

WHOOMPH.

'--damndamndamn!'

Detritus watched Otto roll around on the cobbles screaming.

'What was dat about?' he said, eventually.

'He's taken a picture of you not letting me into the palace,' said William.

Detritus, although born above the snowline on some distant mountain, a troll who had never seen a human until he was five years old, nevertheless was a policeman to his craggy, dragging fingertips and reacted accordingly.

'He can't do dat,' he said.

William pulled out his notebook and poised his pencil. 'Could you explain to my readers exactly why not?' he said.

Detritus looked around, a little worried. 'Where are dey?'

'No, I mean I'm going to write down what you say.'

Basic policing rushed to Detritus's aid once again. 'You can't do dat,' he said.

Then can I write down why I can't write anything down?' William said, smiling brightly.

Detritus reached up and moved a little lever on the side of his helmet. A barely audible whirring noise became fractionally louder. The troll had a helmet with a clockwork fan, to blow air across his silicon brain when overheating threatened to reduce its operating efficiency. Right now he obviously needed a cooler head.

'Ah. Dis is some kind of politics, right?' he said.

'Um, maybe. Sorry.'

Otto had staggered to his feet and was fiddling with the icono-graph again.

Detritus reached a decision. He nodded to a constable.

'Fiddyment, you take dese... two to Mister Vimes. Dey are not to fall down any steps on der way or any stuff like dat.'

Mister Vimes, thought William, as they hurried after the constable. All the watchmen called him that. The man had been a knight and was now a duke and a commander, but they called him Mister. And it was Mister, too, the full two syllables, not the everyday unheeded 'Mr'; it was the 'mister' you used when you wanted to say things like Tut down that crossbow and turn around real slow, mister.' He wondered why.

William had not been brought up to respect the Watch. They weren't our kind of people. It was conceded that they were useful, like sheepdogs, because clearly someone had to keep people in order, heavens knew, but only a fool would let a sheepdog sleep in the parlour. The Watch, in other words, was a regrettably necessary sub-set of the criminal classes, a section of the population informally defined by Lord de Worde as anyone with less than a thousand dollars a year.

William's family and everyone they knew also had a mental map of the city that was divided into parts where you found upstanding citizens and other parts where you found criminals. It had come as a shock to them... no, he corrected himself, it had come as an affront to learn that Vimes operated on a different map. Apparently he'd instructed his men to use the front door when calling at any

building, even in broad daylight, when sheer common sense said that they should use the back, just like any other servant.* The man simply had no idea.

That Vetinari had made him a duke was just another example of the Patrician's lack of grip.

William therefore felt predisposed to like Vimes, if only because of the type of enemies he made, but as far as he could see everything about the man could be prefaced by the word 'badly', as in -spoken, -educated and -in need of a drink.

Fiddyment stopped in the big hall of the palace.

'Don't you go anywhere and don't you do anything,' he said. 'I'll go and--'

But Vimes was already coming down the wide stairs, trailed by a giant of a man William recognized as Captain Carrot.

You could add '-dressed' to Vimes's list. It wasn't that he wore bad clothes. He just seemed to generate an internal scruffiness field. The man could rumple a helmet.

Fiddyment met them halfway. There was a muttered conversation, out of which the unmistakable words 'He's what?' arose, in Vimes's voice. He glared darkly at William. The expression was clear. It said: it's been a bad day and now there's you.

Vimes walked the rest of the way down the stairs and looked William up and down.

'What is it you're wanting?' he demanded.

'I want to know what's happened here, please,' said William.

'Why?'

'Because people will want to know.'

'Hah! They'll find out soon enough!'

'But who from, sir?'

Vimes walked round William as if he was examining some strange new thing.

'You're Lord de Worde's boy, aren't you?'

'Yes, your grace.'

'Commander will do,' said Vimes sharply. 'And you write that little gossipy thing, right?'

* William's class understood that justice was like coal or potatoes. You ordered it when you needed it.

'Broadly, sir.'

'What was it you did to Sergeant Detritus?'

'I only wrote down what he said, sir.'

'Aha, pulled a pen on him, eh?'

'Sir?'

'Writing things down at people? Teh, tch... that sort of thing only causes trouble.'

Vimes stopped walking round William, but having him glare from a few inches away was no improvement.

'This has not been a nice day,' he said. 'And it's going to get a lot worse. Why should I waste my time talking to you?'

'I can tell you one good reason,' said William.

'Well, go on, then.'

'You should talk to me so that I can write it down, sir. All neat and correct. The actual words you say, right down there on the paper. And you know who I am, and if I get them wrong you know where to find me.'

'So? You're telling me that if I do what you want you'll do what you want?'

'I'm saying, sir, that a lie can run round the world before the truth has got its boots on.'

'Ha! Did you just make that up?'

'No, sir. But you know it's true.'

Vimes sucked on his cigar. 'And you'll let me see what you've written?'

'Of course. I'll make sure you get one of the first papers off the press, sir.'

'I meant before it gets published, and you know it.'

'To tell you the truth, no, I don't think I should do that, sir.'

'I am the Commander of the Watch, lad.'

'Yes, sir. And I'm not. I think that's my point, really, although I'll work on it some more.'

Vimes stared at him a little too long. Then, in a slightly different tone of voice, he said:

'Lord Vetinari was seen by three cleaning maids of the household staff, all respectable ladies, after they were alerted by the barking of his lordship's dog at about seven o'clock this morning. He said'

- here Vimes consulted his own notebook - ' "I've killed him, I've killed him, I'm sorry." They saw what looked very much like a body on the floor. Lord Vetinari was holding a knife. They ran downstairs to fetch someone. On their return they found his lordship missing. The body was that of Rufus Drumknott, the Patrician's personal secretary. He had been stabbed and is seriously ill. A search of the buildings located Lord Vetinari in the stables. He was unconscious on the floor. A horse was saddled. The saddlebags contained... seventy thousand dollars... Captain, this is damn stupid.'

'I know, sir,' said Carrot. They are the facts, sir.'

'But they're not the right facts! They're stupid facts!'

'I know, sir. I can't imagine his lordship trying to kill anyone.'

'Are you mad?' said Vimes. 'I can't imagine him saying sorry!'

Vimes turned and glared at William, as if surprised to find him still there. 'Yes?' he demanded.

'Why was his lordship unconscious, sir?'

Vimes shrugged. 'It looks as though he was trying to get on the horse. He's got a game leg. Maybe he slipped-- I can't believe I'm saying this. Anyway, that's your lot, understand?'

'I'd like to get an iconograph of you, please,' William persisted.

'Why?' .

William thought fast. 'It will reassure the citizens that you are on the case and handling this personally, commander. My iconogra-pher is just downstairs. Otto!'

'Good gods, a damn vamp--' Vimes began.

'He's a Black Ribboner, sir,' Carrot whispered. Vimes rolled his eyes.

'Good mornink,' said Otto. 'Do not be movink, please, you are making a good pattern of light and shade.' He kicked out the legs of the tripod, peered into the iconograph and raised a salamander in its cage.

'Looking this vay, please--'

WHOOMPH.

'--oh, shee-yut!'

Dust floated to the floor. In the midst of it a twist of black ribbon spiralled down.

There was a moment of shocked silence. Then Vimes said, 'What the hell happened just then?'

'Too much flash, I think,' said William. He reached down with a trembling hand and retrieved a small square of card that was sticking out of the little grey cone of the late Otto Chriek.

' "DO NOT BE ALARMED,"' he read. ' "The former bearer of this card has suffered a minor accident. You vill need a drop of blood from any species, and a dustpan and brush."'

'Well, the kitchens are over that way,' said Vimes. 'Sort him out. I don't want my men treading him in all over the damn place.'

'One last thing, sir. Would you like me to say that if anyone saw anything suspicious they should tell you, sir?' said William.

'In this town? We'd need every man on the Watch just to control the queue. Just you be careful what you write, that's all.'

The two watchmen strode away, Carrot giving William a wan smile as he passed.

William busied himself in carefully scraping up Otto with two pages from his notebook and depositing the dust in the bag the vampire used to carry his equipment.

Then it dawned on him that he was alone - Otto probably didn't count at the moment - in the palace with Commander Vimes's permission to be there, if 'the kitchens are over that way' could be parlayed into 'permission'. And William was good with words. Truth was what he told. Honesty was sometimes not the same thing.

He picked up the bag and found his way to the back stairs and the kitchen, whence came a hubbub.

Staff were wandering around with the bewildered air of people with nothing to do who were nevertheless still being paid to do it. William sidled over to a maid who was sobbing into a grubby handkerchief.

'Excuse me, miss, but could you let me have a drop of blood-- Yes, perhaps this isn't the right moment,' he added nervously, as she fled shrieking.

' 'ere, what did you say to our Rene?' said a thickset man, putting down a tray of hot loaves.

'Are you the baker?' said William.

The man gave him a look. 'What does it look like?'

'I can see what it looks like,' said William. There was another look, but this one had just a measure of respect in it. 'I'm still asking the question,' he went on.

'I'm the butcher, as it happens,' said the man. 'Well done. The baker's off sick. And who are you, askin' me questions?'

'Commander Vimes sent me down here,' said William. He was appalled at the ease with which the truth turned into a something that was almost a lie, just by being positioned correctly. He opened his notebook. I'm from the Times. Did you--'

'What, the paper?' said the butcher.

That's right. Did you--'

'Hah! You got it completely up your bum about the winter, y'know. You should've said it was the Year of the Ant, that was the worst. You should've arsked me. I could've put you right.'

'And you are--?'

'Sidney Clancy and Son, aged 39, 11 Long Hogmeat, Purveyors of Finest Cat and Dog Meats to The Gentry... Why aren't you writing it down?'

'Lord Vetinari eats pet food?'

'He doesn't eat much of anything from what I hear. No, I delivers for his dog; Finest stuff. Prime. We sell only the best at 11 Long Hogmeat, open every day from 6 a.m. to mid--'

'Oh, his dog. Right,' said William. 'Er.' He looked around at the throng. Some of those people could tell him things, and he was talking to a dogmeat man. Still...

'Could you let me have a tiny piece of meat?' he said.

'Are you going to put it in the paper?'

'Yes. Sort of. In a way.'

William found a quiet alcove hidden from the general excitement and gingerly let the piece of meat dribble one drop of blood on to the little grey pile.

The dust mushroomed up into the air, became a mass of coloured flecks, became Otto Chriek.

'How vas that vun?' he said. 'Oh

'I think you got the picture,' said William. 'Er, your jacket...'

Part of the sleeve of the vampire's jacket was now the colour and

texture of the stair carpet in the big hall, a rather dull pattern of red and blue.

'Carpet dust got mixed in, I expect,' said Otto. 'Do not be alarmed. Happens all zer time,' He sniffed the sleeve. 'Finest steak? Thank you!'

'It was dog food,' said William the Truthful.

'Dog food?'

'Yes. Grab your stuff and follow me.'

'Dog food?'

'You did say it was finest steak. Lord Vetinari is kind to his dog. Look, don't complain to me. If this sort of thing happens a lot then you ought to carry a little bottle of emergency blood! Otherwise people will do the best they can!'

'Veil, yes, fine, zank you anyvay,' the vampire mumbled, trailing behind him. 'Dog food, dog food, oh dear me... vhere are ve goink now?'

'To the Oblong Office to see where the attack was made,' said William. 'I just hope it isn't being guarded by someone clever.'

'Ve will get into a lot off trouble.'

'Why?' said William. He'd been thinking the same thing, but: why? The palace belonged to the city, more or less. The Watch probably wouldn't like him going in there, but William felt in his bones that you couldn't run a city on the basis of what the Watch liked. The Watch would probably like it if everyone spent their time indoors, with their hands on the table where people could see them.

The door to the Oblong Office was open. Guarding it, if you could truly be said to be on guard whilst leaning against the wall staring at the opposite wall, was Corporal Nobbs. He was smoking a surreptitious cigarette.

'Ah, just the man I was looking for!' said William. That was true. Nobby was more than he'd hoped for.

The cigarette disappeared by magic.

'Am I?' wheezed Nobbs, smoke curling out of his ears.

'Yes, I've been talking to Commander Vimes, and now I would like to see the room where the crime was committed.' William had great hopes of that sentence. It seemed to contain the

words 'and he gave me permission to' without actually doing so.

Corporal Nobbs looked uncertain, but then he noticed the notebook. And Otto. The cigarette appeared between his lips again.

' 'ere, are you from that news paper?'

'That's right,' said William. 'I thought people would be interested in seeing how our brave Watch swings into action at a time like this.'

Corporal Nobbs's skinny chest visibly swelled.

'Corporal Nobby Nobbs, sir, probably 34, bin in uniform since prob'ly ten years old, man and boy.'

William felt he ought to make a show of writing this down. 'Probably 34?'

'Our mam has never been one for numbers, sir. Always a bit vague on fine detail, our mam.'

'And...' William took a closer look at the corporal. You had to assume he was a human being because he was broadly the right shape, could talk and wasn't covered in hair. 'Man and boy and... ?' he heard himself say.

'Just man and boy, sir,' said Corporal Nobbs reproachfully. 'Just man and boy.'

'And were you first on the scene, corporal?'

'Last on the scene, sir.'

'And your important job is to... ?'

'Stop anyone going through this door, sir,' said Corporal Nobbs, trying to read William's notes upside down. 'That's "Nobbs" without a "K", sir. It's amazing how people get that wrong. What's he. doing with that box?'

'Got to take a picture of Ankh-Morpork's finest,' said William, easing himself towards the door. Of course, that was a lie, but since it was such an obvious lie he considered that it didn't count. It was like saying the sky was green.

By now Corporal Nobbs was almost leaving the floor under the lifting power of pride.

'Could I have a copy for my mam?' he said.

'Smile, please...' said Otto.

'I am smilin'.'

'Stop smiling, please.'

Click. WHOOMPH.

'Aaarghaarghaargh

A screaming vampire is always the centre of attention. William slipped into the Oblong Office.

Just inside the door was a chalk outline. In coloured chalk. It must have been done by Corporal Nobbs, because he was the only person who would add a pipe and draw in some flowers and clouds.

There was also a stink of peppermint.
