The hairs on the back of Vimes' hand prickled.
He sniffed rankness in the air.
Vimes would be the first to admit that he wasn't a good copper, but he'd probably be spared the chore because lots of other people would happily admit it for him. There was a certain core of stubborn bloody-mindedness there which upset important people, and anyone who upsets important people is automatically hot a good copper. But he'd developed instincts. You couldn't live on the streets of a city all your life without them. In the same way that the whole jungle subtly changes at the distant approach of the hunter, there was an alteration in the feel of the city.
There was something happening here, something wrong, and he couldn't quite see what it was. He started to reach down—
'What is the meaning of this?'
Vimes straightened up. He did not turn around.
'Sergeant Colon, I want you to go back to the Watch House with Nobby and Detritus,' he said. 'Corporal Carrot and Lance-Constable Cuddy, you stay with me.'
'Yes, sah!' said Sergeant Colon, stamping heavily and ripping off a smart salute to annoy the Assassins. Vimes acknowledged it.
Then he turned around.
'Ah, Dr Cruces,' he said.
The Master of Assassins was white with rage, contrasting nicely with the extreme black of his clothing.
'No-one sent for you!' he said. 'What gives you the right to be here, mister policeman? Walking around as if you own the place?'
Vimes paused, his heart singing. He savoured the moment. He'd like to take this moment and press it carefully in a big book, so that when he was old he could take it out occasionally and remember it.
He reached into his breastplate and pulled out the lawyer's letter.
'Well, if you would like the most fundamental reason,' he said, 'it is because I rather think I do.'
A man can be defined by the things he hates. There were quite a lot of things that Captain Vimes hated. Assassins were near the top of the list, just after kings and the undead.
He had to allow, though, that Dr Cruces recovered very quickly. He didn't explode when he read the letter, or argue, or claim it was a forgery. He simply folded it up, handed it back, and said, coldly, 'I see. The freehold, at least.'
'Quite so. Could you tell me what has been happening, please?'
He was aware of other senior Assassins entering the courtyard through the hole in the wall. They were very carefully looking at the debris.
Dr Cruces hesitated for a moment.
'Fireworks,' he said.
'What happened,' said Gaspode, 'was that someone put a dragon in a box right up against the wall inside the courtyard, right, and then they went and hid behind one of the statues and pulled a string and next minute – bang!'
'Bang?'
' 'S'right. Then our friend nips into the hole for a few seconds, right, comes out again, trots around the courtyard and next minute there's Assassins everywhere and he's among 'em. What the hell. Another man in black. No-one notices, see?'
'You mean he's still in there?'
'How do I know? Hoods and cloaks, everyone in black 'How come you were able to fee this?'
'Oh, I always nip into the Assassins' Guild on a Wednesday night. Mixed grill night, see?' Gaspode sighed at Angua's blank expression. 'The cook always does a mixed grill of a Wednesday night. No-one ever eats the black pudding. So it's round the kitchens, see, woof woof, beg beg, who's a good boy then, look at the little bugger, he looks as though he understands every word I'm sayin', let's see what we've got here for a good doggy . . .'
He looked embarrassed for a moment.
'Pride is all very well, but a sausage is a sausage,' he said.
'Fireworks?' said Vimes.
