'Where have you been?' demanded Bartholomew, looking him over to assess any possible damages. 'Are you harmed? What of the riot? Why are you so late? I have been worried!'
'Aha! ' said Michael triumphantly, pulling his arm away.
'Now you know how I feel when you disappear without telling anyone where you are going. Well, like our friend Guy Heppel, I am not a man for foolhardy bravery. I took one look at those mobs last night and took refuge with my beadles in the first University building I came across.
If there were scholars insane enough to be abroad last night, then it would have taken more than me and my men to persuade them back to safety. I spent the night at Peterhouse, safe in a fine feather bed with a bottle of excellent wine to help me sleep. The Master was most hospitable and insisted I stay for breakfast.'
He rubbed at his ample girth with a grin. Bartholomew groaned, feeling exhausted. While he had fretted all night, worrying that Michael might be in the thick of violent fighting, the Benedictine had secured himself some of the most comfortable lodgings in Cambridge.
'Do you have news of what happened?' he asked, thinking that a Peterhouse breakfast must be fine indeed if it could last until so late in the morning. He was sure it had not been watery oatmeal and sour beer.
'I saw the Chancellor on my way here. He and Heppel spent the night cowering in St Mary's Church,' Michael said with a chuckle. 'Courage is not a quality with which us University men are richly endowed, it seems. There was damage, but mostly not major. Only two University buildings came under serious attack: Michaelhouse and Godwinsson, and only Godwinsson sustained any real harm. The students fled to Maud's, so there were no casualties. David's Hostel were out and most of those fiery Scots are currently languishing in Tulyet's prison cells they were rash enough to attempt a skirmish with his soldiers. Master Radbeche was away and Father Andrew was unable to keep them in when the excitement started, although two of them — John of Stirling and Ruthven are still at large.'
He paused in his narrative to assure Father William, who was passing them on his way to terce, that he had survived the night intact.
'Several smaller hostels were set alight,' he continued when William had gone, 'but the fires were doused before they did any real harm. The rioters gained access to about five of them, but you know how poor most of these places are. The would-be looters looked around thinking to find riches galore and were lucky to leave with a couple of pewter plates. If hostels own anything of value at all, it is likely to be a book and the mob had no use for any of those.'
'Is the rioting over, then?'
'Oh yes. A rumour spread that Michaelhouse had shot one of the leaders and it fizzled out like a wet candle.'
'I have been thinking most of the night about the evidence we have gathered so far,' said Bartholomew, tugging at Michael's sleeve to make him walk towards the orchard. 'It is beginning to make sense but there is still much I do not understand.'
'Well, I have given it no thought at all,' said Michael airily, grabbing a handful of oatcakes from a platter in the kitchen as they walked through it. As Agatha turned and saw him, he gave her a leering wink that made her screech with laughter. On their way out, Michael looked at the neat lines of containers filled with water, sand and stones, and spare trestle tables stacked against one wall to be pushed against the back door if necessary.
'If you have been thinking as hard as you say, let us hope these precautions will no longer be necessary,' he said. He became sombre. 'We must put an end to this business, Matt.'
Bartholomew led the way to the fallen tree in the orchard and, as Michael sat on the trunk eating his oatcakes, Bartholomew paced in front of him telling him what he had reasoned.
'We need to consider two things,' he said, running a hand through his hair. 'First, we need to establish the significance of these blue-green rings. And second, We must discover the identity of Norbert.'
'What do you mean, discover his identity?' asked Michael through a mouthful of crumbs. He brushed some off his habit, where they had been sprayed as he spoke.
'He has assumed another identity,' said Bartholomew impatiently. 'Father William told me he became suspicious of Father Andrew's credentials after he had attended one of his masses. He investigated him as only an ex-member of the Inquisition knows how, and discovered that the only Father Andrew from Stirling in Franciscan records died two months ago. William believes Andrew is an impostor.'
That gentle old man?' choked Michael. 'Never! Well, perhaps he might not be Father Andrew from Stirling but I find it hard to believe he is your Norbert.'
'There are, however, four things that suggest Andrew is not all he seems,' Bartholomew continued, ignoring _ Michael's reaction. He scrubbed at his face tiredly and 1 tried to put his thoughts into a logical order. 'First, he said he comes from Stirling. Now, his students, Robert and John, are also from Stirling, claiming to be the sons of a local landlord. I do not want to go into details, but they are nothing of the kind. The towns and villages in Scotland are small and people know each other. I find it hard to believe that Andrew, if he really is from Stirling, would not know that John and Robert's family are not who they claim.'
'Perhaps he does, but is maintaining silence for the sake of these lads,' said Michael. 'It would be in keeping with his character.'
'It is possible, I suppose,' said Bartholomew, disconcerted that the first of his carefully reasoned arguments had been so easily confounded. He tried again. 'Second, when I last visited, Andrew had been writing in his room.
His hands and face were covered in ink, like a child who first learns to write. No real scholar would ever make such a mess.'
'And so, because he does not know how to control his quill, you think he is not a scholar. That is weak, Matt,' warned Michael.
Bartholomew pressed on. 'Third, while all the students have alibis for Kenzie's death and Werbergh's, we did not think to ask the masters. Either Radbeche or Andrew are with the students almost every moment of the day, but where are Radbeche and Andrew when they are not acting nursemaid? We did not think to ask that.'
'That was because we had no cause to ask such a thing,' said Michael with a shrug.
'And fourth.' Bartholomew took a deep breath. 'He was the man at Chesterton tower-house who said there would be a riot last night.'
'What?' exclaimed Michael, leaping to his feet. 'You have not fully recovered your wits, my friend! That is one of the most outrageous claims I have ever heard you make!
And believe me, you have made a fair few!'
'I told you the voice was familiar, but that there was something about it I could not quite place,' said Bartholomew defensively.
'And why is it that you have suddenly remembered this fact now?' asked Michael, not even trying to disguise the sarcasm in his voice.
'It is not a case of remembering,' said Bartholomew, controlling his own sudden flare of anger at Michael's casual dismissal of his revelation. 'It is a case of recognition.
Andrew speaks with a Scottish accent. Well, when 1 overheard him in Chesterton making his proclamation about the riot, he did not. He spoke in the accent of an Englishman. It was his voice, I am certain, but I did not recognise it immediately because he usually disguises it.'
'Oh really, Matt!' said Michael, sitting back down again and stretching out his large legs in front of him. 'The late Master Wilson would be spinning in his grave to hear such wild leaps of logic!'
'Logic be damned!' said Bartholomew vehemently. 'It fits, Michael! If you put all we know together, it fits!'
He sat next to the monk and gave the tree trunk a thump in exasperation. 'We know David's is involved in this business somehow. Ivo, who pre-empted yesterday's riot with his broken cart in the High Street, works at David's. Kenzie was killed, and he was at David's. And the Galen, containing the letters from Norbert to me, was from David's.'
Michael shook his head slowly. 'I accept your point that Andrew is not who he claims, but I cannot accept that he is Norbert. He is too old for a start.'
'Grey hair and whiskers always add years to a man,' said Bartholomew. 'It is probably a disguise to conceal his true age.'
'Maybe, maybe.' Michael picked up another oatcake and crammed it into his mouth so that his next words
