Donor (24 page)

Lisa’s eyes were sparkling with excitement. ‘You’re right,’ she said. ‘That’s exactly what must have happened. But why?’

‘Let’s see. A donor organ becomes available; Médic Ecosse obtains it from the source hospital … but instead of giving it to the patient, they use him or her for one of their animal experiments.’

‘And if it goes wrong, they cover their tracks by substituting the correct one at post-mortem!’ said Lisa.

‘But how do we go about proving it?’

There was a long silence.

‘Let’s eat first,’ said Dunbar, picking up his knife and fork. ‘We’re doing okay.’

They didn’t talk much as they ate, largely because they were both deep in thought. They reached the coffee stage still without coming up with any good idea as to how to prove their theory. It was, however, early days and both of them were pleased about having solved the first bit of the puzzle.

As they left the hotel and wandered down to the jetty to take a look at the lake in the frosty moonlight, Dunbar said, ‘Medical researchers are trained scientists, meticulous people, precise in all things. Facts and figures are of paramount importance to them.’

‘What are you getting at?’

‘I don’t think I’ve ever come across a researcher who didn’t keep notes.’

‘So?’ said Lisa.

‘It’s a basic requirement of the job that you keep accurate records of everything you do in order to write up your results for the journals. You also have to be in a position to show data to back up your claims, should the scientific community request it. All your work is subject to peer review.’

‘I still don’t see what you’re getting at,’ said Lisa, snuggling down deeper into her coat.

‘They must have records somewhere.’

‘Secret notebooks, you mean?’

‘More likely to be computer files these days,’ said Dunbar.

‘So if you could get your hands on them you might find all the evidence you needed?’

‘That’s what I’m thinking,’ he agreed. ‘They must have kept records of all the experiments they’ve done, what went right, what went wrong, what their conclusions were, what they’re going to do next.’

‘Makes sense. But how on earth are you going to get your hands on something like that?’

‘Presumably the records are kept somewhere in Ross’s research lab. I’d have to get in there somehow, but nothing has happened to spook the people in the transplant unit. They’ve no reason to be on their guard. I’m sure I can think of a way and once inside I think I’ll be able to lay hands on what I need. If I could hand the police records of experiments involving the kids, I think we could nail them.’

Lisa looked dubious. ‘I don’t think you should rush into this. It could be dangerous. You don’t really know what you’re up against.’

‘They’re not professional criminals,’ said Dunbar. ‘I think we’re talking about a few ambitious bastards who’ve been cutting corners to speed up their research.’

‘But they’ve killed two children and we think they’re also killing a nursing sister and her husband. Don’t you think that’s an unusually high price for even the most ambitious of researchers to contemplate?’

Dunbar had to agree. ‘You think I’m missing something?’

‘I think it’s possible, and I wouldn’t like it to kill you,’ said Lisa.

‘I’ll bear that in mind.’

‘You haven’t had any more thoughts about the isotope, have you?’

Dunbar shook his head. ‘I suppose Médic Ecosse were just too clever and careful to use one that could be traced back to them. They seem to think of everything – including switching the organs in corpses in case anyone should dig them up and examine them.’

‘You’ll get a break soon,’ said Lisa, slipping her arm into his as they turned back to the car park. ‘I can feel it.’

Dunbar phoned Sci-Med first thing in the morning and spoke to Macmillan. ‘Sir, you asked me to reconcile the nurses’ allegations with the pathologist’s findings. I think I can.’

‘Amaze me,’ said Macmillan drily.

‘They switched the organs after death, probably during the post-mortem.’

‘After death?’

‘It’s still possible they’ve been carrying out experiments on children, using animal organs. They wait until a compatible donor organ becomes available for their patient and then obtain it. But they don’t use it; they just keep it as insurance. If their experiment fails, they replace the animal organ with the human one before releasing the body for burial.’

Macmillan said, ‘Good God, what an awful thought. It’s possible, I suppose, but damn nearly impossible to prove I’d have thought.’

‘I’d like to try but I need more time.’

‘But even supposing you’re right, Dunbar, don’t you think they’d have stopped after the first death?’

‘I’m sorry?’

‘Why didn’t they abandon the whole thing after the first patient died? Why would they continue, knowing the experiment was a failure?’

‘Perhaps they believed they’d solved the problem,’ ventured Dunbar.

‘Mmmm,’ said Macmillan, unconvinced.

Dunbar offered no further argument. Lisa had suggested there was more to it than he thought. Macmillan was doing the same. It was just possible they were right.

THIRTEEN

Dunbar went out for a late-night walk. The earlier rain had stopped, leaving the streets wet but the air cold, dry and mercifully still. He pulled up the collar of his overcoat and set out for nowhere in particular. He just needed to think. Darkness and quiet streets were going to help.

Lisa and Macmillan had given him the uneasy feeling that something was wrong with his whole train of thought. It was the feeling you got when, believing yourself to be on the right road to somewhere, you kept on picking up little clues that said you weren’t. At first, you were reluctant to acknowledge them because you wanted to believe nothing was wrong. You could even convince yourself that you were seeing the landmarks you were supposed to see. You simply altered or modified your expectation to suit. Even as evidence to the contrary mounted, you continued to hope against hope that everything was going to work out, because the alternative meant admitting that you were absolutely lost.

He was afraid the same might apply to his thinking about the use of animal organs for transplant at Médic Ecosse. He had come up with a get-out-of-jail card over that one by mooting a switch of organs after death so, in theory, he could still be right. But now, as he thought it through rationally and without emotion, he started to worry. The little clues were there. He had to steel himself to look at them dispassionately.

Lisa had stuck to her guns so tenaciously because Amy Teasdale’s reaction to her transplant had been so strong. As an experienced transplant nurse, she just couldn’t believe that Amy had been given the right organ. The same was true of Sheila Barnes and her patient, Kenneth Lineham – another strong reaction. What he had found it convenient to ignore until now was the inference that not only had the organs been unsuitable, but they had not even been close in terms of compatibility.

This was a major puzzle and one he’d have to face up to. Ross wasn’t some Mickey Mouse researcher who’d transplant any old organ into a patient to see what happened. He was an acclaimed expert in the field of transplant immunology. He’d know beforehand, through extensive lab work, exactly what the chances of success were. In fact, it seemed entirely reasonable to assume that he wouldn’t even contemplate carrying out experimental surgery unless he was pretty damned sure of success. Yet there had been two spectacular failures. Why?

This in turn begged the question of how many experiments there had been. Were the two failures exceptions to the rule? Had there been lots of successful animal transplants that hadn’t come to light? There was no way of knowing without access to Ross’s research records. There was, of course, the nagging possibility that he was completely and utterly mistaken about the whole thing. Ross had done nothing wrong. There had been no animal transplant experiments. The two kids had suffered from some unknown, non-specific form of tissue rejection, however unlikely the coincidence, and the whole damned investigation had been a mistake from the start.

Dunbar knew he’d have to decide soon which seemed the likelier; the decision about a break-in at Vane Farm was going to be his. He’d be putting himself and Sci-Med at risk, and he needed to feel easier in his mind about the justification for doing so. He sought some resolution of the problem in thinking about the other odd things that had happened at Médic Ecosse.

Going back to the very beginning, he still thought it peculiar and out of character that Ross had accepted the Scottish Office cuts in research funding without much more than a whimper of protest. He’d assumed at the time that Ross must have been promised alternative funding, but if that were so where was it coming from? The fact that he hadn’t been able to find any trace of it didn’t necessarily mean it didn’t exist, but if it didn’t – and even if it did – it was possible that Ross had some other reason for staying on.

Pursuing that line of thought, he wondered whether Ross had allowed himself to be humiliated in public because he had something going on at Médic Ecosse, something he didn’t want interrupted, something so important to him that he was prepared to lose any amount of face. Could research glory be that important to the man? Perhaps. But Ross already enjoyed an international reputation as a researcher. He didn’t need the extra kudos. He wasn’t some young, ambitious buck out to make a name for himself, who’d cut corners if need be.

The more he thought about it, the more unlikely it seemed that Ross would have risked his career and reputation, and killed two children into the bargain, for the sake of stealing a march on the opposition over the issue of animal organs for human transplant. Apart from that, he couldn’t publish the results of his work anyway without advertising his guilt. The best he could do would be to learn from them and start out on a legal programme of research, helped by facts he already knew. Seen in that light, the price seemed unfeasibly high – something Lisa had pointed out. So, if it wasn’t research glory that Ross was after, what could it be?

The obvious answer was money. There certainly seemed to be no limit to what people, at any level in society, would do if the price was right. This was a fact of life. But if money satisfied the question of motive, it obscured the crime. He couldn’t see how anything connected with animal organs for transplant could attract enough money for a man like Ross to risk everything. There was also the problem that Ross didn’t appear to be particularly wealthy. His lifestyle seemed to be roughly in keeping with his eighty-odd thousand a year salary, but of course that could be contrived. Ross was an extremely clever man. He wouldn’t do anything as crass as live beyond his means if he really was involved in something sinister.

Thinking about Ross’s earnings reminded Dunbar that he’d forgotten to ask Sci-Med for more information about Ross’s work in Geneva. It probably wasn’t relevant, but they hadn’t supplied details at the outset. He’d remind them the next time he was in contact. It was untypical of them to have left that unresolved.

Dunbar realized that if he were to implicate Ross in something steeped in self-interest he’d have to explain away Ross’s philanthropic record over transplants for NHS patients at Médic Ecosse. He’d taken on three such patients in three years when he’d been under no pressure at all to do so. The gesture would have significantly reduced profits for his unit and therefore his share of the payout under the old agreement. No one would have quibbled at Médic Ecosse drawing the line at free transplants, especially when they hadn’t been doing well financially, yet they’d taken on three.

Ingrid’s apparent ignorance about the funding of transplants for such patients was another puzzle. He’d thought she’d have been only too keen to confirm that the costs were set off against profits from Omega patients, but, although she’d finally agreed that this was probably the case, she’d behaved as if it were a novel suggestion. It would be worth investigating the funding of these patients further.

Dunbar reminded himself that he hadn’t yet got back to Clive Turner at the Children’s Hospital about the marrow puncture on Amanda Chapman. It wasn’t that he’d forgotten; he simply did not know what to tell him. Officially it had never happened. It was just another strange happening at Médic Ecosse, not terribly important in itself but, again, out of character in an organization that prided itself on efficiency. It would be silly to pretend that people did not make mistakes there, but it would be fair to say they made fewer than most.

The question he had to face up to now was the big one. Did he believe that there was enough reason to warrant a break-in at Vane Farm, with all its attendant risks? He could think of no other way of getting more information about Ross’s research work. The answer, he decided, was yes.

As he crossed one of the bridges over the Clyde, Dunbar paused to lean on the parapet and look down at the dark water swirling below. He was looking for inspiration. Would he attempt the break-in himself or would he call for assistance? He was still pondering this when he became aware of a car slowing down. He half turned and saw that it was a police Panda car; its two occupants were watching him. He returned to looking down at the water, hoping the car would move off. It didn’t. Dunbar heard the window being wound down as the car inched towards him. A Glasgow voice asked, ‘Not thinking of doing anything stupid, are we?’

Dunbar smiled at the irony of the question before turning. He said, ‘Nothing like that, Officer. Just getting some air.’

The answer seemed to satisfy the law. The car moved off.

Definitely not something stupid, thought Dunbar. He had enough egg on his face already over this assignment. He’d ask Sci-Med to arrange expert assistance. Macmillan had said he could stay on the case ‘a bit longer’. He wasn’t too clear what that meant.

Dunbar made his request for help to Sci-Med first thing in the morning. He also asked for information about Ross’s consultancy in Geneva. The reply simply acknowledged the requests and told him they would be dealt with as soon as possible. He should stand by.
