‘You gave him nothing at all?’ asked Michael.
‘No – I have one cure for headaches: sleeping in a darkened room. I have learned through the years that they either get better on their own or they become worse and the patient dies. Nothing the medicus does affects the outcome one way or the other, so I never bother to try.’
‘Did Segeforde have a headache, too?’ asked Bartholomew.
‘He had a pallor,’ replied Nigellus. ‘So all I did for him was recommend an early night.’
‘Now what about this debilitas you have been diagnosing?’ asked Michael. ‘Matt tells me that there is no such sickness.’
Nigellus scowled. ‘Of course there is, and his remark does nothing but underline the fact that I am a better, more experienced medicus than he. He claims to have University degrees, but all I can say is that he cannot have paid much attention in class. I, on the other hand, listened to every word my tutors told me.’
‘When did you study at Oxford?’ asked Michael, aiming to make enquiries to see if Nigellus was telling the truth about his education.
‘Before you were born,’ came the sharp response. He shot Bartholomew an unpleasant sneer. ‘When medical students were of a much higher calibre.’
‘Similia similibus curantur,’ persisted Michael, while Bartholomew felt himself begin to lose patience with Nigellus, and struggled against the urge to turn on his heel and march out. ‘Irby wrote it just before he died. What did he mean?’
‘Clearly, he was reflecting on the best way to counteract the stench caused by Edith Stanmore’s dyeworks.’ The speed of Nigellus’s response indicated that he had already given the question serious consideration. ‘He was pondering whether creating odours of his own would neutralise hers.’
‘Can you prove that?’ asked Michael.
‘Can you disprove it?’ Nigellus flashed back. ‘You think I harmed all these people, but you have no evidence to support your theories, or you would not be here now, fishing for answers.’
Michael stood, refusing to rise to the bait. ‘Thank you for your time. You will no doubt be seeing more of us in the coming days.’
‘I cannot wait,’ said Nigellus acidly. ‘However, do not forget to ask Tynkell how much money is in the University Chest. You will need every penny once Stephen is through with you.’
‘Well?’ asked Michael once they were outside. ‘He had an answer for everything, but only a fellow medicus will know whether his replies were reasonable.’
‘There is something to be said for treating headaches by sending the patient to rest in a dark room, although I suspect he misremembered the sources he quoted.’
‘That does not answer my question.’
‘Letia’s high temperature and sickness should have formed part of Nigellus’s diagnosis, but he chose to ignore them. And it is common knowledge that patients with Irby’s condition can slip into a fatal decline if they fail to eat. Nigellus should have taken steps to prevent it.’
‘So ineptitude rather than malice killed Irby and Letia? What about the others?’
Bartholomew shrugged. ‘He assumed the symptoms exhibited by Lenne and Arnold were diseases, and elected to treat those rather than identify the underlying causes. They might have lived if he had approached them differently, but they might not. We will never know.’
‘Then what about the damage to stomachs and livers that you found in the three Zachary men and Lenne?’ Michael was sounding exasperated. ‘You said that might be evidence of poison.’
‘Yes – might be evidence of poison. But I cannot prove it.’
‘I am not very impressed with your help in this matter, Matt. If you do not give me something useful soon, I may be forced to let him go.’
‘Well, if you do, it should be on condition that he does not practise medicine again. Do you have the authority to enforce that?’
‘Yes, but only temporarily. He will contest my decision and Stephen will argue that he be permitted to trade until the case is resolved in court. Thank God we have Irby’s note – the only truly compelling piece of evidence against him.’
Bartholomew was thoughtful. ‘His explanation of the note made no sense: if Irby had been reflecting on how best to combat the reek from the dyeworks, why did he address his letter to me, the brother of the owner? Why not Nigellus, the medicus in his hostel? Or one of his colleagues?’
‘Those are good questions,’ said Michael. ‘And one we shall ponder while he sits in my gaol.’
While Michael went to do battle with Stephen, Bartholomew trudged home to Michaelhouse, wanting no more than a quiet evening in the conclave. Unfortunately, the porter handed him a long list of patients who needed to see him. Given the uneasy atmosphere, Bartholomew was reluctant to venture out alone, and as Cynric was with Edith, he took two students instead – Melton and Bell.
‘Prior Joliet is a gifted speaker,’ said Melton, as they walked to the home of a wealthy merchant. Bartholomew did not have many rich patients, but Rob Upton did a lot of business with Edith and thought hiring her brother was an easy way to stay in her good books. ‘But Father William refused to let us take any breaks, so it was one long, continuous session.’
‘What about the noonday meal?’
‘Cancelled,’ scowled Melton. ‘To save money after the lavish display we put on over Hallow-tide. So now we are starving.’
Upton claimed he was suffering from the debilitas, although Bartholomew suspected that the half-empty plate of marchpanes might have more than a little to do with the patient’s ‘griping in the guts’. He asked enough questions to prove himself right, and set about writing out the remedy for over-indulgence that he was often obliged to dispense to those with more money than sense.
‘Three other burgesses fell ill with the debilitas today,’ whispered Upton miserably, ‘while it killed Lenne, Arnold, Letia and the scholars from Zachary.’
‘You will feel better tomorrow,’ Bartholomew assured him, ‘although you should abstain from rich foods for a few days. And that includes marchpanes.’
‘Let me try one,’ begged Bell plaintively. ‘To assess whether they are safe.’
Bartholomew shot him an admonishing glance, but that did not stop the lad from snagging one on the way out anyway.
‘Too sweet,’ was the verdict once they were outside. ‘Like eating pure honey. No wonder Upton was queasy. But now I am hungrier than ever, and I doubt I shall sleep tonight.’
‘Nor will I,’ moaned Melton. ‘The pangs are growing worse by the moment.’
Bartholomew took them to the Brazen George, where Landlord Lister provided a large plate of tasty scraps for a very reasonable price. When they had finished, they went to Gonville Hall, where a Fellow named Osborne was suffering from a weakness in the legs. As Osborne reeked of claret, Bartholomew could not imagine why Rougham should want a second opinion as to what was wrong.
‘It came on him gradually,’ Rougham explained. ‘He cannot stand without falling over.’
When he heard how much Osborne had imbibed, Bartholomew was not surprised.
‘He drank to help with the discomfort of his debilitas,’ added another Fellow. ‘His knees were wobbly before his three jugs of wine.’
Declining to comment, Bartholomew prescribed a large bowl of his favourite cure-all – boiled barley water – and an early night. Afterwards, he accepted the offer of refreshments in Rougham’s quarters, where he was provided with wine so dry as to be almost unpalatable. While he warmed himself by the fire, he told Rougham what Nigellus had claimed about the patients he had lost.
