'I want you to remove some instrument packs and screen them for bacterial contamination.'

'If you say so,' said Evans. 'These ones too?' he asked seeing what Jamieson was carrying.

'No. These are the ones they are going to use,' said Jamieson. 'They just don't know it yet.' He looked at his watch and added, 'I'll stop by your office in fifteen minutes. We'll go up to Gynaecology together.'

Jamieson returned to his room and called Sci Med in London. Miss Roberts said that no one was available at the moment could he leave a message? Jamieson said that he needed to know the time of death of last night's killing in Leeds as soon as it was established. Miss Roberts said that she would pass on his request.

Jamieson's heart sank when he got to theatre and found Thelwell scrubbing up. Thelwell spoke first. 'I take it there's no objection to my being present as an observer in my own theatre?' he said acidly.

'None,' said Jamieson flatly. 'Provided that your swabs are still negative, you've applied nasal barrier cream, and you don't approach the table directly.'

'My swabs were always negative.' said Thelwell through tight lips. 'But I've used Naseptin as I always did in the past in any case.'

Jamieson joined Thelwell at the basins and started to scrub his hands and forearms. Clive Evans did the same.'

'I see we have a member of our esteemed Microbiology Department present,' sneered Thelwell. 'To what do we owe this honour?'

'I am here at Dr Jamieson's request,' said Evans without emotion.

'Ah yes,' said Thelwell with what for him, passed for a smile.

The surgical team of Phillip Morton, an assistant, the anaesthetist, the theatre sister and a junior nurse were waiting when Thelwell, Jamieson and Clive Evans joined them.

'May we begin?' asked Morton.

'Not yet,' said Jamieson. He turned to the theatre sister and asked, 'Sister will you please show me the instrument packs for this morning's operation.'

The nurse showed Jamieson the packs without comment and he examined the numbers. He had to swallow when he saw that they were different from the numbers on the packs that he had found in the cupboard the night before. These ones were the ones that had been missing from the cupboard! These were the ones that Thelwell had collected from CSSD personally! They must have been put into the cupboard at some time during the night. Jamieson went over to the cupboard and looked for the packs that had been in there. They had gone.

Jamieson turned round and said to Morton, 'I want you to use these instruments this morning.' He nodded to the packs that Evans was holding. 'Dr Evans is going to take the other ones away for analysis.'

'What on earth is going on?' exclaimed Morton.

'I'm sorry. Explanations will have to wait,' said Jamieson. 'Please just do as I ask.'

'Very good,' said Morton with a shrug of his shoulders.

'Wait!' interrupted Thelwell. 'Might I remind you all that this is still my department and my theatre. I demand to know what is going on!'

'Call it simply a spot check on surgical instruments,' said Jamieson. 'You have no objection to that have you Mr Thelwell?'

Jamieson could see the burning anger in Thelwell's eyes over the mask. 'I prefer to be kept informed of these things,' said Thelwell. 'Is that too much to ask?'

'Spot checks wouldn't be spot checks if they were advertised,' said Jamieson.

'May I proceed?' asked Phillip Morton with more than a trace of impatience in his voice.

'Of course,' said Jamieson. 'We are just leaving.'

As Clive Evans reached the door of the theatre he collided with Thelwell who had turned to leave at the same time. The instruments he had been carrying were scattered all over the floor outside the door.

'Clumsy oaf!' snorted Thelwell and disappeared out through the swing doors. Evans turned to face Jamieson, looking bemused. 'He deliberately barged into me!' he exclaimed.

Jamieson looked at the knives, scalpels and forceps lying all over the floor and sighed in frustration. The tests for sterility would now be useless. Evans began picking up the instruments. 'What do you want done with them?' he asked.

'Return them to CSSD for cleaning and sterilising,' said Jamieson. 'I'm going to have a word with Mr Thelwell.

Jamieson was furious at what Thelwell had done but he was also afraid of what it inferred. If Thelwell had deliberately bumped into Evans, it must mean that he had done it to prevent microbiological examination of the instruments. It had been a clever thing to do on the spur of the moment. Quick thinking, clever and devious. Wasn't that how Ryan had listed the hallmarks of the psychopath?

Jamieson found Thelwell in his office opening letters. His secretary had not been in the outer office so Jamieson had simply pushed open the door which had not been properly closed. At first Thelwell was unaware that he was standing there. He was obviously still in a temper and it showed in the way he was opening the envelopes with what a silver paper knife. He inserted the blade at a corner with momentary precision and then ripped each envelope open with a single upwards slash. Jamieson cleared his throat and Thelwell stopped what he was doing and looked up.

'What do you want?' he snapped. 'Or is it another spot test?' He punctuated the remark with a snort.

Jamieson had to work at keeping the anger he felt under control. He said, 'You have just prevented the examination of the surgical instruments in your theatre by spreading them all over the floor. I think that demands some explanation.'

'What the hell are you talking about?' rasped Thelwell. 'That idiot from Microbiology barged right into me. A typical Richardson protege. Now, if you will be so kind, I have things to do.' Thelwell sat down and started to read his mail. He pretended that Jamieson was no longer standing there.

Jamieson said slowly and quietly, 'I want to know exactly what you did with the instruments you collected from CSSD yesterday.' He watched Thelwell carefully for his reaction.

Thelwell stopped reading, settled back in his chair and let out his breath in a long, slow sigh. 'My, we have been busy,' he said.

Jamieson waited for his answer.

'I brought them back here.'

'Where?'

'Here, to my department.'

'Why should a consultant surgeon play at being a hospital porter?' asked Jamieson slowly.

'Because this consultant surgeon cares enough about his patients to monitor the sterilising of the instruments to be used in their operations and then make sure that they are not tampered with before they are used.'

Jamieson found himself taken unawares by the directness of Thelwell's answer. He had to be careful. He wasn't dealing with a fool. Was the man just clever? Or very clever? Clever enough to pretend that he was investigating the very act that he could see he was about to be accused of?

'Tampered with?' said Jamieson.

'It occurred to me that this was a possibility,' said Thelwell.

'I see,' replied Jamieson. He tried to trap Thelwell by saying, 'So yesterday you brought the instruments up to the theatre from CSSD and put them away in the theatre instrument cupboard yourself?'

'Not exactly,' said Thelwell, walking round the trap. 'I kept them locked away in my desk overnight. I put them in theatre this morning shortly before the operation was about to commence.'

'And the instruments that already were in theatre?'

Thelwell unlocked the cupboard in the left pedestal of his desk and brought out the packs he had substituted. 'I was going to take them back to CSSD for re-sterilising.'

'Have you any reason to believe that instruments have been tampered with?' Jamieson asked.

'Just a precaution,' replied Thelwell. 'But I felt it was warranted. As the same thought has obviously occurred to you, you can hardly argue the point.'
