One was missing.
Which was impossible. Although it was badly decomposed, Noah Harper’s body had been fully intact when we’d exhumed it. If one of his cervical vertebra had been absent we’d certainly have noticed.
So where was it?
With an odd sense of certainty, I went over to where the microscope stood on the workbench. I felt no surprise when I saw the small white object on the stage beneath the lens. If anything I should have realized before. I’d wondered what Tom had been doing in here when he’d had his heart attack.
Now I knew.
The image was blurred when I looked through the eyepiece. I adjusted the focus until the vertebra swam into view. It was as delicately fluted and spurred as coral, its porous surface appearing pitted under the magnification.
The hairline cracks looked as deep as a chasm.
Straightening, I took the piece of bone from under the microscope. The fractures were almost invisible to normal eyesight. There were two of them, one on each of the laminae, the slender bone bridges that link the main body of the vertebra to its more delicate neural arch.
Feeling strangely clear-headed, I set it down and went back down the corridor to the autopsy suite where Tom had been working. Going straight to Terry Loomis’s skeleton, I picked up the sixth cervical vertebra from the examination table and held it up to the light. The fractures were even less obvious than on the laminae I’d just seen. But they were there all the same.
So that was it. I felt no satisfaction, only a sudden welling of sadness. This was Tom’s discovery, not mine. I took out my phone and called Paul.
‘I know how they were killed.’
‘So it’s definitely strangulation.’
Paul looked dispassionately down at the vertebra he was holding. We were in Tom’s autopsy suite. I’d already shown him the fractures in Noah Harper’s sixth cervical vertebra before bringing him in here to examine the matching cracks in Terry Loomis’s.
‘I can’t see any other way you’d get such precise breaks,’ I said. While a blow to the back of the neck could have broken the vertebra, the damage would have been much more extensive. And the chances of blunt trauma causing near identical injuries to two different victims was too remote to consider. No, these fractures were the result of something altogether more focused. More controlled.
That was a word that seemed to figure a lot with York.
‘At least now we know for sure how Loomis and Harper came by the pink teeth,’ Paul agreed. ‘And it explains what Tom was doing in the other autopsy suite. He found the fractures in Loomis’s vertebra and went to see if Harper’s had them as well. That how you see it?’
‘More or less.’ And then York had phoned him while he was examining it under the microscope. I supposed there was an irony there, but wasn’t sure what it was.
Paul gently set down the bone. ‘Lord, it makes you want to weep.’
He sounded as exhausted as he looked. Tom’s death had hit him hard, and the false alarm with Sam the previous night hadn’t helped. He’d cut a faculty meeting short when I’d called him, and the strain of the last few days was evident as soon as he walked in. The lines around his eyes looked etched, and patches of blue-black bristles were already shading the pallor of his chin where he’d shaved in a rush.
He tried to stifle a yawn. ‘Sorry.’
‘Do you want to get some coffee?’ I asked him.
‘Later.’ He made an effort to pull himself together. ‘What about the cervical vertebrae from the remains in the woods? Have you checked them as well?’
‘While I was waiting for you to get here. Two of them are missing, but the rest are all intact. Including the sixth.’ That was no surprise. Willis Dexter had died in a car crash, not been murdered like Noah Harper or Terry Loomis.
‘So we’re looking at a steady pressure exerted on both victims’ necks, powerful enough to fracture the laminae but without breaking the hyoid.’ Paul held up his hands and considered them. ‘Can you remember how big York’s hands were?’
‘Not big enough to do this.’ The only thing I could recall about York’s hands was their nicotine-stained fingers. But both Loomis and Harper had been grown men; it would have taken a huge span to wrap far enough round their necks to fracture the vertebrae. And that would more than likely have broken the hyoid as well.
‘Most likely some kind of ligature or garrotte rather than manual strangulation,’ Paul said. ‘Whatever he used, it must’ve fastened around their necks at exactly the same point, causing identical damage to the same vertebra each time. Hard to say exactly what it was, though.’
‘Tom had worked it out.’
He looked at me in surprise. ‘He did?’
‘Remember what he said to Mary when he was taken into hospital? Spanish. At the time we didn’t know what he could have meant.’
It was a further sign of Paul’s tiredness that it took him a moment to make the connection. ‘Spanish windlass. Christ, I should have realized.’
So should I. Wrap a bandage or piece of cloth round a bleeding limb, then place a stick underneath and twist it. That was a Spanish windlass. At its most basic it was little more than an improvised tourniquet that could be wound tighter or loosened at will, a simple device that had saved countless lives.
But not the way York had used it.
I thought about the photographs the TBI had found in York’s garage. The agonized expressions of his victims, their dark and swollen faces. Suffused with blood as York had incrementally tightened the windlass, steadily choking the life out of them.
And photographing it as it happened.
I pushed the images from my mind. ‘York might not even have realized he was leaving any visible evidence at all. There’d be no way for him to know the laminae had been fractured. And even if he noticed the pink teeth, they’re a pretty obscure phenomenon. He might not have realized their significance.’
‘That still brings us back to the blood in the cabin,’ Paul said. ‘Loomis was strangled, so there’s no way it’s all his. So who the hell’s is it?’
‘Another of York’s games, perhaps?’ I said. The DNA analysis would tell us eventually, but I’d an idea that we might not have to wait as long as that.
Paul gave a weary shrug. ‘I spoke to Gardner earlier. He didn’t come right out and admit it, but they’re obviously taking your theory about Tom seriously. The bottom line is they can’t rule out that York might try for someone else on the investigation now he’s screwed up his chances with him.’
I suppose that should have occurred to me, but somehow it hadn’t. I’d been too wrapped up with what had happened to Tom to follow the idea to its logical conclusion.
‘So what’s Gardner going to do?’
‘Not much he can do except warn people to be careful,’ Paul said. ‘He can’t wrap everyone in cotton wool, and there isn’t the manpower to do it even if he wanted to.’
‘I’ll consider myself warned.’
He smiled, but there wasn’t much humour in it. ‘Just keeps getting better and better, doesn’t it? Turned out to be one helluva research trip for you.’
It had, but I was still glad I’d come. I wouldn’t have missed the chance to work with Tom, regardless of how it had turned out.
‘Are you worried?’ I asked.
Paul’s stubble rasped as he passed a hand across his face. ‘Not really. York had surprise on his side before, but he’s lost that now. I’m not saying I won’t be careful, but I’m not going to spend my life looking over my shoulder in case some psycho decides to come after me.’
‘You get used to it after a while,’ I said.
He gave me a startled look, then broke out in a laugh. ‘Yeah, I suppose you do at that.’ He grew serious. ‘Look, David, if you want to bow out, no one’s going to blame you. This isn’t your problem.’
I knew he meant well, but the reminder still felt like a slap. ‘Perhaps not. But it sort of feels like it is.’
Paul nodded, then looked at his watch and grimaced. ‘Sorry, but I’ve got to go. Another damn faculty meeting. Things should settle down in a day or two, but right now I need to be in two places at once.’
The silence of the autopsy suite seemed to press in around me after the door had closed behind him. I looked down at the partially assembled skeleton waiting on the examination table, and thought of Tom.
Clearing my mind, I went back to work.
I worked even later than I’d intended. Partly because I wanted to make up for lost time, but also because the thought of spending the evening alone back at my hotel held little appeal. As long as I was busy, I could hold off confronting the fact of Tom’s death for a little longer.
But that wasn’t the only thing that was bothering me. The feeling of oppression I’d felt after Paul’s visit stubbornly refused to diminish. My senses seemed oddly heightened. The mortuary’s chemical stink was underlaid with an indefinable biological odour, a faint hint of the butcher’s slab. The white tiles and metal surfaces gleamed coldly in the harsh light. But it was the silence that I was most aware of. There was the distant hum of a generator, more felt than heard, the constant plip of a dripping tap. But, other than that, nothing. Normally I didn’t even notice the quiet.
Now I felt it all around me.
Of course, I knew all too well what was the matter. Until Paul had mentioned it I’d never considered the possibility that York might target someone else from the investigation. My concern had been all for Tom, and even after what had happened to Irving, I’d blindly assumed that he was the only one under threat. But it was naive to think that York would stop with his death.
