Poseidon's Wake

Оглавление

Sadalmelik had fallen over onto his side, crushing one of the tubular sculptures in the process. He was so motionless that at first glance Goma thought he was dead. But he was still breathing, albeit with a slow, laboured rhythm, and as she watched, the tip of his trunk tried to lift itself from the ground.

‘No,’ Ru said, rushing past Goma.

Goma joined her at the fallen creature’s side. Eldasich and Achernar flanked her, still on their feet, but it only took a glance to confirm that they were also ailing — their breathing heavy, their eyes red and weeping with a white suppuration. A similar whiteness spilled from the sides of their mouths.

‘Fetch her,’ Ru said, kneeling to place a hand on Sadalmelik.

‘What is it?’

‘I don’t know. Something fast — they’d have raised a warning otherwise. What are you waiting for? Go!’

Goma went. She raced back up the corridor to the camp’s human accommodation. Eunice was where she had left her — seated at her table, discussing arrangements with Vasin.

Goma was breathless. She had to fight to get the words out.

‘You have to come.’

‘What’s the matter?’

‘I don’t know. Something’s wrong with Sadalmelik. The others don’t look good, either.’

Eunice was already rising from her table. ‘He’s sick?’

‘It looks pretty bad. You’d better hurry.’

Eunice went to a cabinet and pulled out a green toolkit. ‘Excuse us, Captain.’

‘No, I’m coming with you. What can it be — an infection? Something we’ve brought with us?’

‘I don’t know. These Tantors have never had contact with anyone other than myself so their immunological response may not be particularly strong. But their ancestors moved freely on Zanzibar in close association with hundreds and thousands of human beings. Nothing should hit them this hard. Have you had any contagious diseases on Crucible since Zanzibar’s departure?’

‘Nothing that should hurt them,’ Goma said. ‘Our own elephant populations have never been affected by anything serious.’ A sudden black despair washed over her. ‘Oh, god. What’s happened? What have we done?’

‘Let’s not assume the worst,’ Eunice said. ‘Sadalmelik had an infected tooth once — it looked very bad at the time, but he recovered.’

‘I’m worried about the other two.’

‘Where is Ru?’

‘Still there. Can I carry anything?’

Eunice hefted the green box. ‘These are my medicines. I seldom get ill, and nor do they. If we need anything more potent, it’ll have to come from your ship, and pray that it works on elephants. But first we need to know what we’re dealing with.’

‘We should act pre-emptively,’ Vasin said. ‘There are portable medical supplies on the lander, some analysis equipment. Saturnin — do you think you could get back there with a tool sled? The ship will open to any one of us, provided it recognises our suits.’

‘There’s a chance I might be more useful here,’ Dr Nhamedjo said. ‘That said, if I suit up and leave immediately, I should be able to get back within half an hour.’

Vasin nodded her assent. ‘Eunice — will your locks allow him to come and go, even if you’re down with the Tantors?’

‘I’ll make sure they do. Grab a sled and load up as much as you can — antibiotics, antivirals, anything you have. Are you comfortable going out there on your own?’

‘I could go with him,’ Loring said.

‘Thank you,’ Nhamedjo said, ‘but the trail’s clear enough, and I’ve been back to the lander since we arrived. I won’t get lost.’

‘The others can’t be far from the camp by now,’ Eunice said. ‘If you see them, move with caution and don’t block their way. The formal introductions will have to wait.’

While Nhamedjo went to suit up and make the short trek back to the lander, the rest of the party raced down to the Tantors. Eunice and Goma took the lead, but at the door the older woman raised a hand. ‘Goma and Ru have already had close contact with the Tantors; the rest of you haven’t. Let’s keep it that way for now.’

‘Surely you don’t think it’s anything to do with them?’ Vasin said.

‘I’m taking no chances. Wait outside this door until we have a better idea of what’s happening.’

Eunice sealed the door behind her, locking Goma and Ru in with her and the Tantors. She made an adjustment to the room’s air pressure and air-circulation settings.

Ru was still kneeling at Sadalmelik’s side, a hand on his trunk. It could not have been more than four or five minutes since Goma left, but Sadalmelik’s condition had clearly worsened. Having witnessed the death of Agrippa, the progression was as unmistakable as it was harrowing.

Eunice knelt down and snapped open her medical kit. There was more in it than Goma had been expecting, and it was all very neatly organised. She took out an enormous syringe, stabbed it hard into Sadalmelik’s thigh and drew a dense purple cylinder of blood. She slotted the blood sample into the maw of some kind of miniature analysis device built into the kit.

‘Plasma assay will take a few minutes to run,’ she said, tapping a finger against a tiny readout in the top of the analyser. ‘In the meantime, I’m going to take a chance on a double bolus of broad-spectrum antibiotics and antivirals.’ She dug deeper into the kit, produced another heavy-duty syringe filled with straw-coloured liquid. ‘It’s worked before, so it may give him a fighting chance. Eldasich, Achernar — what happened? When did you all start feeling unwell?’

‘They say they can’t breathe,’ Ru said. ‘It started during the night — coughing, fluid build-up in their lungs.’ She was looking up at Goma from her kneeling position, abject concern on her face, nearly crying from the distress of it all. ‘Sadalmelik was the first to succumb, but Eldasich and Achernar are going the same way. It’s something we brought, isn’t it?’

‘Eldasich,’ Eunice said again, ‘Achernar — I know this is hard, but we need to isolate the three of you. I want you to move into the secondary chambers — one in each. We’ll do what we can for Sadalmelik, but I have to think of you as well.’

‘Will Sadalmelik pass into the Remembering?’ asked Achernar.

‘Not if I can help it. But all three of you are ill and I don’t know what’s causing it. Trust me to do my best for you.’

‘We will leave him,’ Eldasich said.

Eunice recharged the syringe and injected the other two Tantors. ‘This may or may not make any difference, but it’s all I can do for the moment. Think hard, both of you — did either of you feel ill before the people arrived? Did you notice anything wrong with Sadalmelik?’

‘We were well,’ Achernar said. ‘This came quickly.’

‘Then it must be connected to their arrival somehow,’ Eunice said, in a deliberate, judicial tone.

With visible reluctance, Achernar and Eldasich moved away from their fallen friend and trudged into the adjoining chambers. Eunice promised she would look in on them later, then sealed the connecting doors.

Goma, meanwhile, stood helpless, desperate to be doing something but utterly at a loss as to how she could help. ‘Test our blood as well,’ she said. ‘Just in case.’

‘I was about to. Has either of you experienced a recent illness?’

‘Other than Ru’s AOTS, we’ve both been fine.’

This drew sharp interest from Eunice. ‘AOTS?’

‘Accumulated Oxygen Toxicity Syndrome — it’s a condition, not a disease,’ Ru answered. ‘The oxygen partial pressure on Crucible is high, but we’ve adapted to it with drugs and therapies. I lapsed on the drugs — allowed myself to suffer oxygen toxicity over a prolonged period.’

‘Go on,’ Eunice said.

‘At its worst, it’s like a persistent case of the bends. But that was years ago — I’ve been managing it ever since. Besides, as I said, it’s not contagious.’

‘What about bacterial pneumonia?’ Eunice asked as she prepared to take the two human blood samples.

‘What about it?’ Goma asked.

‘Zoonotic infection. It’s hopped from people to elephants in the past — usually with fatal consequences.’

‘Neither of us has pneumonia,’ Ru said.

‘We’ll see.’

Eunice drew blood from both of them, docked the syringes with the analyser, tapped buttons on its keypad. The machine was already making whirring and clicking sounds, interspersed with the whine of high-speed centrifuges and pumps. While it was preoccupied, Eunice moved to a bucket, retrieved a wet sponge and used it to soothe Sadalmelik. ‘Easy, my friend,’ she whispered, dabbing around his eye. ‘We’ve come through a lot, you and me. Too soon to bow out just yet.’

Sadalmelik’s trunk moved. Eunice stroked it, closed her fingers around the tip.

‘I’m right here.’

The analyser chirped — it had completed the first battery of tests. Eunice peered at the cryptic numbers and symbols of the readout. ‘A viral infection,’ she said, delivering the news neutrally. ‘Give it a little while and it will attempt to cook up a targeted antiviral.’

‘Attempt?’ Goma asked.

‘It isn’t perfect.’

The device gave two more chirps. The earlier medical data shuffled aside, replaced by more numbers and symbols. Goma knew some basic medical biology but this was too arcane for her, and the technology of the assay device was unfamiliar. ‘Well, the good news is that neither of you has an elevated viral load,’ Eunice said, after a moment’s consideration of the numbers. ‘You had the closest contact with the Tantors, so that was my first suspicion. But if it’s something airborne, any one of the others could be responsible.’
