The Chemistry of Death Hardcover - 2006

Chapter One


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.
