The Chemistry of Death

Synopsis:

When the bizarrely mutilated and long-dead body of a young woman is found in a ditch in Manham, an isolated and insular village in the Norfolk marshlands, it isn't just the fact that she had been a friend that disturbs Dr David Hunter. He was once a high-profile forensic anthropologist and all too familiar with the different faces of death, until a devastating personal tragedy made him turn his back on his former life and career. Now hidden away as a country doctor, Hunter's past is a secret he hopes will remain buried. So when he's asked by the police to use his arcane skills to help track down the killer, he's reluctant to become involved, knowing this will only stir up the painful memories he's been trying so hard to forget. Then another young woman disappears, and Manham is plunged into a fog of fear and paranoia that threatens to tear it apart. And no one seems exempt from suspicion as the twisted killings continue. And as the once peaceful community is riven by fear and mistrust, David Hunter realises it will take all his knowledge and expertise if the killer is to be stopped. But not even he is prepared for the terrible cost that will exact -- or the awful price that failure threatens to bring...

A human body starts to decompose four minutes after death. Once the encapsulation of life, it now undergoes its final metamorphoses. It begins to digest itself. Cells dissolve from the inside out. Tissue turns to liquid, then to gas. No longer animate, the body becomes an immovable feast for other organisms. Bacteria first, then insects. Flies. Eggs are laid, then hatch. The larvae feed on the nutrient-rich broth, and then migrate. They leave the body in orderly fashion, following each other in a neat procession that always heads south. South-east or south-west sometimes, but never north. No-one knows why.

By now the body's muscle protein has broken down, producing a potent chemical brew. Lethal to vegetation, it kills the grass as the larvae crawl through it, forming an umbilical of death that extends back the way they came. In the right conditions -- dry and hot, say, without rain -- it can extend for yards, a wavering brown conga-line of fat yellow grubs. It's a curious sight, and for the curious what could be more natural than to follow this phenomenon back to its source? Which was how the Yates boys found what was left of Sally Palmer.

Neil and Sam came across the maggot trail on the edge of Farnham Wood, where it borders the marsh. It was the second week of July, and already the unnatural summer seemed to have been going on for ever. The heat seemed eternal, leaching the colour from the trees and baking the ground to the hardness of bone. The boys were on their way to Willow Hole, a reed pond that passed as the local swimming pool. They were meeting friends there, and would spend the Sunday afternoon bombing into the tepid green water from an overhanging tree. At least, so they thought.

I see them as bored and listless, drugged by the heat and impatient with each other. Neil, at eleven three years older than his brother, would be walking slightly ahead of Sam to demonstrate his impatience. There's a stick in his hand, with which he whips the stalks and branches he passes. Sam trudges along behind, sniffing from time to time. Not from a summer cold, but from the hay fever that also reddens his eyes. A mild antihistamine would help him, but at this stage he doesn't know that. He always sniffs during summer. Always the shadow to his bigger brother, he walks with his head down, which is why he and not his brother notices the maggot trail.

He stops and examines it before shouting Neil back. Neil is reluctant, but Sam has obviously found something. He tries to act unimpressed, but the undulating line of maggots intrigues him just as much as it does his brother. The two of them crouch over the grubs, pushing dark hair out of similar faces and wrinkling their noses at the ammoniac smell. And though neither could later remember whose idea it was to see where they were coming from, I imagine it to be Neil's. Having walked past the maggots himself, he would be keen to assert his authority once more. So it's Neil who sets off first, heading towards the yellowed tufts of marsh grass from which the larvae are flowing, and leaving Sam to follow.

Did they notice the smell as they approached? Probably. It would be strong enough to cut through even Sam's blocked sinuses. And they probably knew what it was. No city boys, these, they would be familiar with the cycle of life and death. The flies, too, would have alerted them, a somnolent buzzing that seemed to fill the heat. But the body they discovered was not the sheep or deer, or even dog, they might have expected. Naked but unrecognizable in the sun, Sally Palmer was full of movement, a rippling infestation that boiled under her skin and erupted from mouth and nose, as well as the other less natural openings in her body. The maggots that spilled from her pooled on the ground before crawling away in the line that now stretched beyond the Yates boys.

I don't suppose it matters which one broke first, but I think it would be Neil. As ever, Sam would have taken his cue from his big brother, trying to keep up in a race that led them first home, then to the police station.

And then, finally, to me.

As well as a mild sedative, I also gave Sam antihistamine to help his hay fever. By this time, though, he wasn't the only one to have red eyes. Neil too was still shaken by their discovery, although now he was beginning to recover his juvenile poise. So it was he rather than Sam who told me what had happened, already starting to reduce the raw memory to a more acceptable form, a story to be told and retold. And later, when the tragic events of that preternaturally hot summer had run their course, years later Neil would be telling it still, forever identified as the one whose discovery had started it all.

But it hadn't. It was just that, until then, we had never realized what was living among us.

I came to Manham in the late afternoon of a wet March, three years earlier. I arrived in the train station -- little more than a small platform in the middle of nowhere -- to find a rainswept landscape that seemed as empty of human life as it was of contour. I stood with my suitcase and took in the surrounding scenery, barely noticing the rain that dripped down the back of my collar. Flat marshland and fens spread out around me, a linear topography broken only by patches of bare woodland as it stretched to the horizon.

It was my first time in the Broads, my first time in Norfolk. It was spectacularly unfamiliar. I took in the sweeping openness, breathed in the damp, cold air, and felt something, minimally, begin to unwind. Unwelcoming as it might have been, it wasn't London, and that was enough.

There was no-one to meet me. I hadn't arranged any transport from the station. I hadn't planned that far ahead. I'd sold my car, along with everything else, and not given a thought to how I would get to the village. I still wasn't thinking too clearly, back then. If I'd thought about it at all, with the arrogance of a city-dweller I'd assumed there would be taxis, a shop, something. But there was no taxi rank, not even a phone box. I briefly regretted giving away my mobile, then picked up my suitcase and headed for the road. When I reached it there were just two options, left or right. Without hesitating I took the left. No reason. After a few hundred yards I came across a junction with a faded wooden road sign. It leaned to one side, so that it seemed to be pointing into the wet earth to some point underground. But at least it told me I was heading in the right direction.

The light was fading when I finally reached the village. One or two cars had passed as I'd walked, but none had stopped. Other than those, the first signs of life were a few farms set well back from the road, each isolated from the other. Then ahead of me in the half-light I saw the tower of a church, apparently half-buried in a field. There was a pavement now, narrow and slick with rain but better than the verge and hedgerows I'd been using since leaving the train station. Another bend in the road revealed the village itself, virtually hidden until you stumbled across it.

It wasn't quite a picture postcard. It was too lived in, too sprawling to fit the image of a rural English village. On the outskirts was a band of pre-war houses, but these soon gave way to stone cottages, their walls pebbled with chunks of flint. They grew progressively older as I drew nearer to the heart of the village, each step taking me further back in history. Varnished with drizzle, they huddled against each other, their lifeless windows reflecting back at me with blank suspicion.

After a while the road became lined with closed shops, behind which more houses ran off into the wet dusk. I passed a school, a pub, and then came to a village green. It was ablaze with daffodils, their yellow trumpets shockingly colourful in the sepia world as they nodded in the rain. Towering over the green, a gigantic old horse chestnut spread its bare black branches. Behind it, surrounded by a graveyard of canted, moss-covered stones, was the Norman church whose tower I'd seen from the road. Like the older cottages, its walls were encrusted with flint; hard, fist-sized stones that defied the elements. But the softer mortar surrounding them was weathered and worn by age, and the church windows and door had subtly warped as the ground it stood on had shifted over the centuries.

I stopped. Further on I could see that the road gave way to more houses. It was obvious that this was pretty much all there was to Manham. Lights were on in some of the windows, but there was no other sign of life. I stood in the rain, unsure which way to go. Then I heard a noise and saw two gardeners at work in the graveyard. Oblivious to the rain and dying light, they were raking and tidying the grass around the old stones. They carried on without looking up as I approached.

'Can you tell me where the doctor's surgery is?' I asked, water dripping down my face.

They both stopped and regarded me, so alike despite the disparity in their ages that they had to be grandfather and grandson. Both faces held the same placid, incurious expression, from which stared calm, cornflower-blue eyes. The older one motioned towards a narrow, tree-lined lane at the far side of the green.

'Straigh' up there.'

The accent was another confirmation I was no longer in London, a coiling of vowels that sounded alien to my city ears. I thanked them, but they'd already turned back to their work. I went up the lane, the sound of the rain amplified as it dripped through the overhanging branches. After a while I came to a wide gate barring the entrance to a narrow drive. Fixed to one of the gateposts was a sign saying 'Bank House'. Beneath it was a brass plaque that said 'Dr H. Maitland'. Flanked by yews, the drive ran gently uphill through well-kept gardens, then dropped down to the courtyard of an imposing Georgian house. I scraped the mud from my shoes on the worn cast-iron bar set to one side of the front door, then raised the heavy knocker and rapped loudly. I was about to knock again when the door was opened.

A plump, middle-aged woman with immaculate iron-grey hair looked out at me.

'Yes?'

'I'm here to see Dr Maitland.'

She frowned. 'The surgery's closed. And I'm afraid the doctor isn't making home visits at the moment.'

'No... I mean, he's expecting me.' That brought no response. I became aware of how bedraggled I must look after an hour's walk in the rain. 'I'm here about the post. David Hunter?'

Her face lit up. 'Oh, I'm
so
sorry! I didn't realize. I thought... Come in, please.' She stood back to let me in. 'Goodness, you're soaked. Have you walked far?'

'From the station.'

'The train station? But that's miles!' She was already helping me off with my coat. 'Why didn't you call to tell us when your train was in? We could have had someone pick you up.'

I didn't answer. The truth was it hadn't occurred to me.

'Come through into the lounge. The fire's lit in there. No, leave your case,' she said, turning from hanging up my coat. She smiled. For the first time I noticed the strain evident in her face. What I'd taken earlier for terseness was just fatigue. 'No-one'll steal it here.'
