'I don't know. I've never seen anything like it . . . there was just a great big hole. But I'm going to find out what it was.'

'Hmm. Did I mention that Dr Cruces came to see me this morning?'

'No, sir.'

'He was very . . . concerned.'

'Yes, sir.'

'I think you upset him.'

'Sir?'

The Patrician seemed to be reaching a decision. His chair thumped forward.

'Captain Vimes—'

'Sir?'

'I know that you are retiring the day after tomorrow and feel, therefore, a little . . . restless. But while you are captain of the Night Watch I am asking you to follow two very specific instructions . . .'

'Sir?'

'You will cease any investigations connected with this theft from the Assassins' Guild. Do you understand? It is entirely Guild business.'

'Sir.' Vimes kept his face carefully immobile.

'I'm choosing to believe that the unspoken word in that sentence was a yes, captain.'

'Sir.'

'And that one, too. As for the matter of the unfortunate Mr Hammerhock . . . The body was discovered just a short while ago?'

'Yes, sir.'

'Then it's out of your jurisdiction, captain.'

'What? Sir?'

'The Day Watch can deal with it.'

'But we've never bothered with that hours-of-daylight jurisdiction stuff!'

'Nevertheless, in the current circumstances I shall instruct Captain Quirke to take over the investigation, if it turns out that one is necessary.'

If one is necessary. If people don't end up with half their

chest gone by accident. Meteorite strike, perhaps, thought Vimes.

He took a deep breath and leaned on the Patrician's desk.

'Mayonnaise Quirke couldn't find his arse with an atlas! And he's got no idea about how to talk to dwarfs! He calls them gritsuckers! My men found the body! It's my jurisdiction!'

The Patrician glanced at Vimes' hands. Vimes removed them from the desk as if it had suddenly grown red-hot.

'Night Watch. That's what you are, captain. Your writ runs in the hours of darkness.'

'It's dwarfs we're talking about! If we don't get it right, they'll take the law into their own hands! That usually means chopping the head off the nearest troll! And you'll put Quirke on this?'
