At last they came to a door set in an alcove. It looked strong enough to hold back the sea. There was a tiny grille.
'Hey!' shouted Rincewind. It wasn't very useful, but he couldn't think of anything better.
There was a sudden silence. Then a voice from the other side of the door said, very slowly, Who is out there?'
Rincewind recognised that voice. It had jerked him from daydreams into terror on many a hot classroom afternoon, years before. It was Lemuel Panter, who had once made it his personal business to hammer the rudiments of scrying and summoning into young Rincewind's head. He remembered the eyes like gimlets in a piggy face and the voice saying 'And now Mister Rincewind will come out here and draw the relevant symbol on the board' and the million mile walk past the waiting class as he tried desperately to remember what the voice had been droning on about five minutes before. Even now his throat was going dry with terror and randomised guilt. The Dungeon Dimensions just weren't in it.
'Please sir, it's me, sir, Rincewind, sir,'he squeaked. He saw Twoflower and Bethan staring at him, and coughed, 'Yes,' he added, in as deep a voice as he could manage. That's who it is. Rincewind. Right.'
There was a susurration of whispers on the other side of the door.
'Rincewind?'
'Prince who?'
'I remember a boy who wasn't any—'
'The spell, remember?'
'Rincewind?'
There was a pause. Then the voice said, 'I suppose the key isn't in the lock, is it?'
'No,' said Rincewind.
'What did he say?'
'He said no.'
'Typical of the boy.'
'Um, who is in there?' said Rincewind.
'The Masters of Wizardry,' said the voice, haughtily.
'Why?'
There was another pause, and then a conference of embarrassed whispers.
'We, uh, got locked in,' said the voice, reluctantly.
'What, with the Octavo?'
Whisper, whisper.
'The Octavo, in fact, isn't in here, in fact,' said the voice slowly.
'Oh. But you are?' said Rincewind, as politely as possible while grinning like a necrophiliac in a morgue.
'That would appear to be the case.'
'Is there anything we can get you?' said Twoflower anxiously.
'You could try getting us out.'
'Could we pick the lock?' said Bethan.
'No use,' said Rincewind. 'Totally thief-proof.'
