Another thought. I looked at the sample bags, thinking hard. The ones I’d used for the beakers were already half empty – if I did it again, there’d be none left for future experiments. I dithered for a moment. Using it all up felt like stealing from a dead man.
Hagger’s gone, I told myself. If he was lucky, he’d get a small plaque in the mess, maybe a photograph on the wall with the other ghosts. The samples would get tipped down the sink if I didn’t use them.
I emptied the two bags and repeated the experiment – three beakers, three samples, 10ml of Echo Bay water in each – but this time I cut three pieces off one of the pipes, and dropped them in. They bobbed about on the surface, like the last remnants of a shipwreck.
The voice over my shoulder made me jump. ‘All staff, please report to the mess for an urgent briefing.’
The gist of the meeting was that everyone’s confined to base. Quam blamed the inevitable Health and Safety. It’s fair to say the staff aren’t happy: Eastman, in particular, gave Quam a hard time. I slouched in my seat and tried not to get blamed.
Afterwards, Eastman came to visit me. No particular reason; I wonder what he wanted to know. I don’t trust him. If I had to pick anyone at Zodiac who I thought might be capable of murder, it would be him. Superficially, he’s got that all-American charm: energetic, engaging and very good teeth. But if you look at the eyes, there’s something dead, as if there’s a small man inside his head pulling levers to operate the smile.
He asked how I was doing. It’s getting tedious answering that question – I feel like an elderly aunt who’s had a fall. I suppose I should be grateful for the sympathy. Then he asked about my work. Flipped through the notebook, which I didn’t like, and found the sheet of paper that nearly killed me chasing after it in the wind. The one with the strange noughts, ones and twos.
‘It’s mine,’ Eastman said.
That was news. But he didn’t know any more than that; it’s just some piece of radio garbage he picked up interfering with the instruments. Nothing to do with anything Hagger was working on.
‘Nothing about DAR-X in the notebook?’
I told him that Hagger had taken some samples at Echo Bay.
‘He ever do any work at Vitangelsk?’
‘Not that I know of.’
‘How about that key?’
Eastman’s like that: always moving on. I’m sure when he was a kid they stuffed him full of Ritalin. I told him how I’d found the key at the crevasse, not mentioning Greta’s theory that it came from Hagger’s killer. He made a joke about Hagger’s liquor cabinet, which I laughed at dutifully, but I didn’t like the way he looked at the key. I’d have locked it away if I could – but, of course, I couldn’t. Ironic. I hid it as best I could in a drawer full of lab equipment as soon as he’d gone. Then I took a sample from each of my beakers, strained them and stained them and put them under the microscope.
The green sample and tap water showed no change. But in the red sample – and especially the red sample with the piece of pipe – you could see even without counting that there were more bugs in the water than there were two hours ago.
I looked at the graph in Hagger’s notebook again. Apparently, this should be just the beginning.
Forty-one
Anderson’s Journal – Friday
I’m writing this by torchlight, burrowed down in my sleeping bag like a boy reading past his bedtime. Except it’s not kids’ games any more. There’s a storm raging outside so fierce it ripped off the anemometer; I think our communications dish has gone too. It sounds as though the whole Platform might blow away.
I’m not on the Platform. I’ve shut myself in the caboose they call Star Command. It sounds melodramatic, but I can’t take any more risks.
Another gust of wind. The caboose is one of those round domes, like a diver’s helmet; it’s anchored into the ice, so it ought to be secure. But that wind … I can imagine it picking up the whole island and dropping us somewhere in Mongolia.
The key was gone this morning. I suspect Eastman, from the way he was looking at it yesterday. A horrible thought: what if it’s his? What if he was the one who dropped it by the crevasse? Maybe he came back for it Monday afternoon, and hit me on the head while Annabel’s back was turned?
I went to confront him, but I couldn’t find him anywhere, even with everyone confined to base. I asked Quam, who said he hadn’t seen him. He wouldn’t meet my eye as he said it.
First the notebooks, now the key. Whatever Hagger was on to, someone at Zodiac is after it.
But they didn’t touch the samples. I know, because I shut them in the fumes cupboard, with a strand of hair jammed in the door that would fall out if anyone opened it. Silly stuff I got from a spy novel. Hard to believe it’s real life.
First thing this morning, I got out the beakers and examined them. Even without the microscope, the results were startling. In the green samples and the tap water, no change. But the red sample without the pipe was cloudy, and the one with the pipe in it looked like milk of magnesia.
I lifted out the pipe fragment with a pair of tweezers. The yellow plastic had turned brown, the smooth surface pitted and eroded. The sides were smeared with a translucent white sludge that, under the microscope, turned into a writhing mass of tiny worms, feasting on the pipe like maggots on old meat.
I put it back in the beaker so they could continue their meal in peace.
‘Bon appétit,’ I said to them.
‘Talking to your experiments is the second sign of madness,’ said Greta behind me. I jumped.
‘What’s the first?’
She snorted, as if it was obvious. ‘Coming to Zodiac.’
She glanced at the row of beakers, but didn’t ask what I was doing.
‘I think I’ve made a breakthrough,’ I told her.
She didn’t look impressed.
‘DAR-X were having a problem with corrosion on their pipes. Martin went to Echo Bay to take a look, as a favour.’ I slipped the sample under the microscope and beckoned her over. ‘See what he found?’
She bent over it stiffly, like someone peering over the edge of a cliff.
‘Worms.’
‘Micro-organisms, feeding on the pipes from the drill rig. Methane was seeping out; that’s why Fridge got abnormal readings. But Martin wasn’t interested in the bugs. He wanted to know why they were growing there.’
She looked up from the microscope.
‘Can bugs really eat plastic?’
I nodded. ‘You’ve seen plastic burn? As a rule of thumb, anything that burns has energy in it, and plastic is incredibly rich. It’s made from petroleum, after all. These bacteria can metabolise that into food energy.’
‘Smart.’
‘But there’s something else in the water, something helping them reproduce.’ I paused. ‘Something that’s making all the sea life on that coast explode, from plankton to polar bears.’
‘So what is it?’
I deflated. ‘I don’t know. I don’t even know where it came from. It just pops up in the Helbreensfjord, as if by magic, then floats away on the Stokke current.’
‘The glacier?’
‘That would be the obvious candidate. But Martin tested it from top to bottom and couldn’t find a trace.’ I thought of all the green-ringed X’s on the map. ‘That’s what he was doing the day he died.’
‘Did he know what it was?’
I spread the notebook open on the bench and turned through it. ‘I think so. Look here.’
It was one of the last pages he’d written on. Another list of the samples (I know the references by heart, now) – with a set of numbers against each one.
‘What does “ppm” mean?’ Greta asked, reading one of the headings.
‘Parts per million. It’s a measurement of concentration.’
She pointed to the numbers. ‘Is it a lot?’
‘Depends on what it’s referring to. If you’re talking nitric acid, twenty-five parts per million is bad news. Som
ething like ammonia, two or three hundred wouldn’t do you much harm.’
(The values Hagger got fluctuate, but for the red samples they mostly sit in the high hundreds. In the green samples, next to nothing.)
‘If he knew the measurements, he must have known what he was measuring.’ I waved my hand around the room. ‘The thing is, I can’t work out how he did it. To test that many samples he’d have needed chemicals, titration equipment, maybe a mass spectrometer.’ Even knowing what he used would give me a clue what he was looking for. ‘There’s nothing like that here.’
After a moment, I realised Greta had gone quiet. I mean, she’s never exactly forthcoming, but this was a more deliberate silence. Provocative, almost.
‘What?’
‘I know where Martin kept his equipment.’
A shadow went through me when I saw the crucified Buzz Lightyear toy nailed over the door of the caboose they call Star Command. Luke has one just like it. But I forgot it the moment I stepped through the door.
There was a mattress on the floor, raised off the ground on a couple of pallets. Two sleeping bags zipped together on top of it. Most of the rest of the room was taken up with a table, and the three machines on it. They didn’t look much different from desktop printers, or maybe a fancy water cooler. One was a mass spectrometer. One was a thermal cycler for replicating DNA. The third was a DNA sequencer. Hagger’s usual mess filled in the gaps: test tubes, spare nozzles, used chemical hand warmers that looked like teabags, and half a dozen empty plastic bottles.
‘Why didn’t you tell me about this before?’
Greta gave me a hard look. I glanced at the mattress again, with its double sleeping bag and twin pillows. The caboose would be a cold place to sleep; you’d freeze if you tried to undress. But maybe two people could warm it up a bit. If they wanted some privacy.
That wasn’t my business. ‘Do you know what Hagger was doing here? With the instruments?’
‘We didn’t talk much about work.’
It took an effort of will not to look at the bed again.
‘That’s a DNA sequencer,’ I said, in the too loud voice of an embarrassed Englishman. ‘He must have been trying to sequence that little worm he found eating DAR-X’s pipes.’
Greta gave the sequencer a once-over, with the practical eye of a mechanic. I got the feeling she was wondering how it would come apart.
‘I thought he was a chemist.’
‘Biochemist,’ I corrected. ‘Sort of both.’ I wondered how much she knew. ‘Martin worked at the boundary of biology and chemistry. What he was interested in, what made him famous, was his work on the origins of life question.’
‘OK.’
‘Maybe you’ve heard of the idea that life evolved in the tropics, in nutrient-rich pools. You’ve heard the phrase “primordial soup”?’
If she had, she was giving nothing away.
‘Martin didn’t agree with that. He used to say that putting all the ingredients in the bowl doesn’t make a soup. Someone has to stir it. He believed that the cycles of the Arctic sea ice, freezing and melting and freezing again, year after year, were what stirred up the soup and made the ingredients mix.’
If that sounds fluent, it’s because I used to hear Hagger give the same spiel, time and again, when I was in his lab. And, almost always, get the same objection.
‘There’s no life in the Arctic.’
‘That’s not true. When the sea ice forms, the salt in the seawater gets left behind. Gradually, the water that remains gets saltier and saltier, until it’s too salty to freeze. The ice forms a crystal lattice, with tiny holes in between where the supersaturated salt water stays liquid. And each of those holes is effectively a test tube, where any DNA particles in the water can combine and replicate to their hearts’ content. When the lattice melts, the DNA’s released into the wild, until the seawater freezes again. And each time, those strands of DNA get a little longer, until eventually they cross the threshold and become life.’
‘It’s a magical time,’ said Greta.
‘The point is, Martin found proof. Here, at Zodiac. The sea-ice samples he took a couple of years ago – when he analysed them he found that stray DNA in the water was mutating and recombining at an astonishing rate. Off the scale.’
Off the scale. Like the graph Hagger had drawn of those bugs.
‘He took the samples back to Cambridge and ran some experiments. Basically, popping them in and out of the freezer a few hundred times and then seeing what was there. He’d nailed it: the longest strand of DNA ever observed naturally forming.’
I remembered reading the paper when it came out in Nature. I’d like to say I was happy for him, but that wasn’t exactly true. I’d wondered what might have been if I’d stayed with him, not switched my supervisor all those years ago. Maybe it would have been my name on that paper as first author, my lab drowning in money from all the funding bodies dying to be associated with my research. Maybe even my wife toasting me with champagne, explaining to Luke what all the fuss was about.
And maybe it would have been me lying at the bottom of that crevasse, said the bit of my brain that picks holes in everything.
The wind had risen and I’d forgotten my goggles. Walking back to the Platform from Star Command, I had to shield my face with my glove, eyes screwed almost shut against the ice that found its way inside my hood. The clouds were so low you could hardly see the far side of the fjord. I’d never imagined that perpetual daylight could get so dark. On the roof of the Platform, I could see some of the antennas bending like whips. A good day to be inside.
A folded piece of paper had landed on my desk. A mobile phone number with a +44 prefix, in handwriting so bad it could only be a doctor’s. Underneath he’d written, Burn after reading. I assumed that was a joke.
I rang the number from the radio room. After a week in the Arctic, the homely brrrr-brrrr of the phone ringing sounded like a message from Mars.
K-Mart answered with a cheerful ‘Yuh?’ that became a guarded ‘OK’ when I told him who I was. I didn’t expect any more. I’m the man who took his job.
‘Is this about the compromise agreement?’
‘Martin Hagger’s dead.’
‘Wow.’ He sounded winded. ‘That’s … I had no idea. I’ve been on holiday. I am on holiday,’ he corrected himself. ‘Wow.’
‘I’m trying to tie up a few loose ends in his work.’ Like: Why did it get him killed?
‘Right. Yeah. Of course.’
‘He died before I got here, so I didn’t get a chance to speak to him.’
‘Uh-huh.’
‘I wonder if you can tell me what exactly he expected me to do here.’
A long pause. ‘You probably know more about that than me.’
‘He didn’t tell me anything.’
‘Well he didn’t tell me, for sure. Just told me to pack my bags.’
‘Because of your tooth.’
His voice got less laid-back. ‘There was no tooth. That was a story he and Doc put together. Something to do with funding, procedure, something like that. The truth is, he wanted to get rid of me because he thought you knew more than me.’
‘I didn’t …’
‘I don’t care,’ he said, in the voice of someone who does. ‘He was the worst supervisor, just gave me donkey work. Running around the island, collecting samples. Wouldn’t even tell me about the enzyme.’
‘What enzyme?’
Ignored. ‘Look, I’m sorry he’s dead and no hard feelings and all that. But you’re the one who wanted the job. You figure it out.’
‘I didn’t want it,’ I objected. But he’d hung up.
While I was there, I logged on to the computer to Skype Luke. It took so long to connect I gave up; then, just as I stood to go, he appeared on screen. He was wearing his Spiderman costume over his school uniform, and he looked sad. It made my heart break, in a minor way. Superheroes and children shouldn’t look so unhappy.
‘The lady said your plane crashed
.’
I gave one of those artificial smiles you give children, and twisted my head one way, then the other. ‘See? No damage.’
‘When are you coming home?’
‘I don’t know,’ I admitted. ‘We have to wait for a new plane.’
‘I miss you.’
‘I miss you too.’ But I was speaking to no one: the screen had gone blank. I thought the storm must have knocked out the Internet, but a few moments later a sentence appeared in the box next to the video window.
Are u there?
Still here. We’re having a storm.
Is there lightening?
With the limited bandwidth, and Luke’s typing, the letters stuttered across the screen. I found myself getting impatient with him, and then ashamed for being impatient. It wasn’t his fault. Since it ended with Louise, I’ve been reliant on Luke for so much. It’s too much weight to put on an eight-year-old.
Our conversation quickly collapsed into monosyllables. He must be getting impatient, too. I tried not to take it personally, though you always do, with your children.
The connection was so slow, I began leafing through Hagger’s notebook while I waited. Only marginally less frustrating, but at least it was something to do.
What is X?
Maybe Anderson?
Absorbed, I didn’t realise Luke was waiting for me to reply. I looked up to see a line of gibberish on the screen.
DGEBAPB
At first I thought the storm had mangled the transmission. Then I realised it was a riddle, a fad they had been going through at school when I left. Abbreviating sentences and making you guess what it stood for. The sort of unwinnable game schoolboys love.
I thought about it for a little bit, but I didn’t have the patience. Who knows what an eight-year-old’s mind will come up with?
I give up
The reply took a good five minutes to come through. Maybe he’d wandered off, or started playing his Nintendo.
