'Fireworks?' said Vimes.
Dr Cruces looked like a man grasping a floating log in a choppy sea.
'Yes. Fireworks. Yes. For Founder's Day. Unfortunately someone threw away a lighted match which ignited the box.' Dr Cruces suddenly smiled. 'My dear Captain Vimes,' he said, clapping his hands, 'much as I appreciate your concern, I really—'
'They were stored in that room over there?' said Vimes.
'Yes, but that's of no account—'
Vimes crossed to the hole in the wall and peered inside. A couple of Assassins glanced at Dr Cruces and reached nonchalantly towards various areas of their clothing. He shook his head. His caution might have had something to do with the way Carrot put his hand on the hilt of his sword, but it could also have been because Assassins did have a certain code, after all. It was dishonourable to kill someone if you weren't being paid.
'It seems to be some kind of . . . museum,' said Vimes. 'Guild memorabilia, that sort of thing?'
'Yes, exactly. Odd and ends. You know how they mount up over the years.'
'Oh. Well, that all seems in order,' said Vimes. 'Sorry to have troubled you, doctor. I will be going. I hope I have not inconvenienced you in any way.'
'Of course not! Glad to have been able to put your mind at rest.'
They were ushered gently yet firmly towards the gateway.
'I should clean up this glass,' said Captain Vimes, glancing at the debris again. 'Someone could hurt themselves, all this glass lying around. Wouldn't like to see one of your people get hurt.'
'We Shall be doing it right this minute, captain,' said Dr Cruces.
'Good. Good. Thank you very much.' Captain Vimes paused at the doorway, and then thumped the palm of his hand on his forehead. 'Sorry, excuse me – mind like a sieve these days – what was it you said was stolen?'
Not a muscle, not a sinew moved on Dr Cruces' face.
'I didn't say anything was stolen, Captain Vimes.'
Vimes gaped at him for a moment.
'Right! Sorry! Of course, you didn't. . . Apologies . . . Work getting on top of me, I expect. I'll be going, then.'
The door slammed in his face.
'Right,' said Vimes.
'Captain, why—?' Carrot began. Vimes held up a hand.
'That wraps it up, then,' he said, slightly louder than necessary. 'Nothing to worry about. Let's get back to the Yard. Where's Lance-Constable Whatshername?'
'Here, captain,' said Angua, stepping out of the alley.
'Hiding, eh? And what's that?'
'Woof woof whine whine.'
'It's a little dog, captain.'
'Good grief.'
The clang of the big corroded Inhumation Bell echoed through the Assassins' Guild. Black-clad figures came running from all directions, pushing and shoving in their haste to get to the courtyard.
The Guild council, assembled hurriedly outside Dr Cruces' office. His deputy, Mr Downey, knocked tentatively at the door.
'Come.'
