Say You're Sorry(110)



My mobile vibrates against my heart. There is a text message from Dr. Leece at the hospital: he wants to see me.

The vertical blinds are drawn in the pathologist’s office. I knock. A voice tells me to enter. John Leece is sitting in semi-darkness, reclined on a leather office chair with a wet flannel over his eyes. A lone desk lamp throws a circle of light over a series of post-mortem photographs arranged on his desk.

“A migraine,” he explains, without removing the flannel. “I’ve been plagued by them since childhood.”

He motions me to sit down.

“There are times when I’d gladly put a bullet in my head to be rid of the pain.”

“Quicker than aspirin,” I say.

“Rather more permanent.”

He folds the flannel and dips his fingers in a glass of water before wiping them across his eyelids. I’m studying the photographs on his desk. One of them shows Natasha’s body beneath the ice, her face in soft focus. A shaft of sunlight has pierced the clouds and illuminated the snow, creating a halo around her head. She looks almost peaceful, as though she’s been laid to rest in a mausoleum of ice.

“You wanted to see me.”

“Have you heard of tritium?”

“No.”

“It’s a hydrogen atom that has two neutrons in the nucleus and a single proton. Although it can be a gas, it most commonly reacts with H2O to form tritiated water. Colorless. Odorless. Although not particularly dangerous, it’s considered to be a low-level radioactive hazard with a half-life of 12.3 years. The molecule is so small it enters the body very easily—inhalation, ingestion, even through the skin.”

“Why are you telling me this?”

“Traces of tritium showed up in Natasha’s urine. At some point she ingested the molecules, probably in contaminated water. Maybe she bathed in the water or was given it to drink.”

“Radioactive water?”

“Normally it would be excreted through her urine within about thirty days of ingestion, so she must have been contaminated in the past month.”

“Is it dangerous?”

“Tritium is created naturally in the upper atmosphere when cosmic rays strike air molecules, but it’s also produced during nuclear weapons explosions or as a by-product of nuclear reactors. It’s a pollutant that in large enough doses can cause cancers, congenital malformations and genetic mutations.”

“Where was she contaminated? Radley Lakes?”

“It’s a wildlife sanctuary. They test the water regularly. Contamination at these levels would have showed up.” He gets to his feet and crosses the office to his desk. “I talked to someone from the Nuclear Decommissioning Authority. He didn’t believe me at first. He said tritium exposure is almost unknown but that occasionally there had been accidental releases into the cooling water of nuclear power plants or into the effluent stream as waste.”

“So what you’re saying is that Natasha was exposed to some form of nuclear waste or spillage?”

“Yes.”

“From a nuclear power plant?”

“That’s the most likely source.”

“Didcot Power Station?”

“Didcot is coal and oil,” says Leece.

“Where then?”

“I was thinking about Harwell. It’s only sixteen miles south of here.”

“I thought it was decommissioned years ago,” I say.

“The last three reactors were closed in 1990 and the land was remediated, but there are still storage sites with radioactive material. It’s going to take another ten years to clean them up.”

Dr. Leece opens his laptop and calls up the results of an Internet search. Harwell was Britain’s first nuclear reactor, set up in the 1940s when the government handed over an RAF base to the Atomic Energy Research Establishment.

“Treated waste water from the old nuclear plant was piped to the Thames at a place called Sutton Courtenay, which is only a couple of miles south of Radley Lakes.”

He calls up Google Earth. A picture of the planet appears on screen, as though taken from outer space. The camera plunges towards the surface, falling onto Oxfordshire. Slowing. Stopping. Focusing.

“There’s also this place,” says Dr. Leece. “The Culham Science Center is a research laboratory experimenting with nuclear fusion as part of the Joint European Torus project.”

“Where is it?”

“About a mile south of Radley Lakes.”

“So the tritium could have come from there?”

“I’m just suggesting it’s a possibility.”

I look at the screen. The main railway line from Oxford to Didcot runs past the research center. Natasha McBain could have followed the tracks in the blizzard, trying to get home.
