Friar Alarm!

Back inside the cathedral, the bishop finds Friar Knowledge in conversation with Friar Conviction. In a fiery mood, Baldwin rounds on the former.
'What did I tell you - no talking to anyone unless I'm also present!'

'I felt sorry for the captain', says Friar Knowledge, sadly. 'He looked so distraught. I wondered if I could help him'.

'Well of course you could help him - you're the one that drugged the emperor! But I think that we could all agree that it would probably improve the chances of the success of our plan to hide the emperor, if you didn't tell his guards that we were the ones who abducted him!'

The two friars nod - to be fair, the bishop has a point.

'Anyway', continues Baldwin, 'did it all go to plan? When you slipped the medication into his mulled wine, did he succumb quickly?'

'How strong was the sleeping draught?' asks Friar Knowledge, fiddling with the pages of his book of records.
'Why do you ask', replies the bishop suspiciously. 'You did give him the right amount? That flask had a pint of super-strong sleeping draught, and I said, quite specifically, that you shouldn't give him very much.'
Friar Knowledge holds his thumb and fore-finger just apart, indicating a tiny amount.
'Excellent ...' says the bishop with relief.
'Yes', replies the friar, 'there was that much left'.
'Jumping Jesus', blasphemes the bishop. 'What have you done?'
'Will he sleep in late?' asks Friar Conviction in alarm.
'Late! late!' cries the bishop. 'He'll wake up in the nineteenth century!' You gave him a dose that would be dangerous for an insomniac rhinoceros!'

'What's a rhinoceros?' asks Friar Conviction.

'Well', replies Baldwin, tweaking painfully the friar's nose, 'a key part of a definition would that it is a creature that shouldn't on any account be given a probably lethal dose of sleeping potion'. The bishop rubs his eyes wearily. 'Right, very well. It's done. So, Friar Knowledge, you need to stay out of trouble - go to the library and reorganise the books on heresy according to size'.

'Size of book or size of heresy, Your Holiness?'

'Both - now go. And so, Brother Conviction, we turn to the next question - where have you hidden the emperor?'

'Well, come this way, Your Holiness ...'
