Poseidon's Wake Read online

  Soon enough she was at the study area, and there was the Beta herd – lured in with enticements of fruit and greenbread, then persuaded to take part in cognitive games. Goma and Ru had designed the research programme, but it was mostly down to Ru to shape the individual challenges. Of necessity, these had grown increasingly simple as the elephants’ average intelligence baseline slowly declined. The complex tests – those that demanded a high degree of abstract reasoning – were now obsolete. Only Agrippa could pass them with any regularity, and Agrippa was too old and canny to be a reliable test subject.

  Ru was standing up in her own buggy, back ramrod straight, a cap jammed down over her eyes. With a notebook wedged into the angle of her right arm and a stylus in the other hand, she was recording observations.

  Goma slowed so as not to disturb the experiment. She stopped the buggy, grabbed her things and walked the rest of the way.

  The herd comprised thirty members, give or take, led by the matriarch Bellatrix. There were older females under the matriarch, but the only males were infants and juveniles.

  In a clearing, Ru had set up the day’s sequence of cognitive puzzles, and one by one the elephants were encouraged to try their luck. There were mirrors, to test recognition-of-self. There were pots with food under them that could be moved around, or blinds that served a similar purpose. There were sturdy upright boards set with movable symbols – simple problems of logic and association and memory, with clear rewards for a correct answer. There were piles of objects and tools that could be combined to solve a problem, such as extracting fruit from a container. With her usual diligence, Ru had been working through combinations of these tests all day. The elephants were generally obliging, but only up to a point. Goma knew how frustrating it became when the rewards stopped being sufficiently attractive.

  ‘I could use some good news,’ Goma said when she was within earshot.

  ‘How about you go first. Did you batter those idiots into a pulp?’

  ‘Metaphorically.’

  ‘So we get our brand-new fence?’

  ‘It’s pending, but I think I made a good case.’

  ‘I wouldn’t expect anything less of you. Still, arseholes, the lot of them.’

  ‘I wouldn’t go quite that far.’

  ‘Oh, I would.’ Ru hopped down from the buggy. ‘They’re just playing with us. They could give us ten times the amount we’ve asked for and it wouldn’t make a dent in their funding budget. We’re just down in the noise.’

  They walked towards each other.

  ‘Speaking of noise,’ Goma said, ‘Tomas tells me the numbers aren’t looking great.’

  ‘Dismal, more like. But why are we surprised? Three years ago I could draw a chequer-board in the dirt and play a passable game of Go with Bellatrix. Now she just scuffs her trunk through the squares – it’s as if she almost remembers, but not enough to understand the point. That’s not an intergenerational decline – that’s a single elephant losing intelligence almost as we speak.’

  ‘We should expect some age-related cognitive deterioration. It affects people, so why not pachyderms?’

  ‘We never used to see such a sharp tail-off.’

  ‘I know – just trying to find a slightly less depressing way of looking at it. Have you been out here all day?’

  ‘Got caught up. You know how it goes.’

  They met, embraced, kissed. They held each other for a few seconds, Goma straightening Ru’s cap. Then Goma stepped back and appraised the other woman, noticing the stiffness in her posture and the slight tremble in her hand, the one still holding her notebook. Ru was bigger and taller than Goma, but for all that she was also frailer.

  ‘You’re done for the day. Let’s pack up and drive home.’

  ‘I need to finish this batch of tests.’

  ‘No, you’re done.’ Goma spoke with all the firm authority she could muster, knowing full well that her wife would not take well to being pressured.

  ‘It’s just been a long one. I’ll be fine after a night’s rest.’

  They packed the study items into the rear hoppers of their two buggies. Goma slaved her buggy to follow Ru’s, then joined her in the forward vehicle. Goma opened the storage compartment by the passenger seat, unsurprised to see that it was empty.

  ‘Did you even bring your medicines?’

  ‘I meant to go back for them.’

  ‘You never miss a detail with elephants – why is it so hard to extend the same care to yourself?’

  ‘I’m fine,’ Ru said. But after a moment, she added, ‘Can we detour to swing by Alpha herd? I’d like to take a look at Agrippa.’

  ‘Agrippa can wait – you need your medicine.’

  But it was pointless arguing, especially as Ru was driving. She steered the buggy onto a narrower track, the rear vehicle following, and soon they were cresting a low hill to overlook the favoured gathering spot of Alpha herd. It was near the greened-over corpse of a Provider robot, frozen where it had been when the information wave hit Crucible.

  They stopped. Goma hopped out first, then went around to help Ru step down.

  ‘There she is. Binoculars in the back, if you need them.’

  ‘No, I’ll manage.’ Goma levelled a hand over her eyes, screening out the platinum glare of the clouds. It only took her a few moments to pick out Agrippa, the matriarch of the Alpha herd, but her usual pleasure at recognition with offset with disquiet.

  Something was not right with Agrippa.

  ‘She’s very slow.’

  ‘I noticed that a couple of days ago,’ Ru said. ‘Some lameness for a while, but this is different. I know she’s old, but she’s always had that underlying strength to get her through.’

  ‘We should take some blood.’

  ‘I agree. Bring her in, if necessary. Maybe it’s just an infection, or a bad reaction to something she ate.’

  ‘Possibly.’

  But neither cared to admit the obvious truth: that Agrippa was showing the signs of extreme age rather than of any underlying malady that could be treated with drugs or transfusions. She was simply an old elephant – the oldest of the herd members.

  But also the smartest, according to the cognition measures. The only one who could still pass most of the tests, proving that she had an inner monologue, a sense of her own identity, an understanding of cause and effect, of time’s arrow, of the distinction between life and death. Agrippa could not generate speech sounds, but she could understand spoken statements and formulate symbolic responses. She was the last of the Tantors – the last elephant to carry the fire of true intelligence.

  But Agrippa had grown old, and although her immediate offspring were cleverer than the common herd, they were not as bright as their mother. Her children had produced grandchildren, diluting her genes even further, and these elephants were barely distinguishable from the others. So weak was the signal, it took careful statistical analysis to prove they had any cognitive enhancements.

  ‘We can’t lose her,’ Ru said eventually.

  ‘We will.’

  ‘Then it ends. We’ll have failed.’

  ‘There’s more work to be done. Always will be. We’ll still have all these elephants to look after.’

  ‘They don’t even care. That’s the part that really gets me. We do. It tears us apart to see them losing what they had, year by year. But to them it’s nothing. They don’t miss being Tantors – give them wide-open spaces, food to eat, some mud to roll in – why should they?’

  ‘Being Tantors was not a normal part of elephant development,’ Goma said. ‘We can’t blame them for not caring. Do dogs care that they’re not as clever as bonobos? Do ants care that they’re not as smart as dogs?’

  ‘I care.’

  Goma squeezed her shoulder, then hugged her silently for a few moments. She shared Ru’s creeping despair – the sense of so
mething bright and precious and mercurial slipping through their fingers. The more they tried to measure it, to preserve it, the more quickly it was fading. But she needed Ru to be strong, and in turn Goma needed to be strong for Ru. They were like two trees leaning against each other.

  ‘Let’s go home,’ Goma said. ‘I have to call my mother – I told her I’d visit tomorrow but Agrippa’s bloodwork is more important.’

  ‘I can take care of that,’ Ru said. ‘You know how much Ndege needs her routines.’

  ‘Can you blame her?’

  ‘Not me. I’m the last one who’d blame her for anything.’

  A few days later, when early evening business brought Mposi back to the parliamentary building in Guochang, he found a visitor waiting for him in the annexe to his office.

  ‘Goma,’ he said, beaming. ‘What a pleasant surprise.’

  But his words drew no corresponding sentiment from her, nor even a smile.

  ‘Can we speak? In private?’

  ‘Of course.’

  He let her into the office, still maintaining a façade of polite conviviality even though nothing in her manner suggested this was a social call. That would have been out of character, at least lately. When she had been less busy in both professional and private spheres, Goma had often visited him for a stroll around the parliamentary gardens, both of them trading stories and titbits of innocent rumour. He realised, with a swell of sadness, that he had almost forgotten how much pleasure those simple encounters had brought him, unencumbered by professional obligations on either side.

  ‘Chai?’ he offered, drawing the office blinds against a lowering sun as fat and red as a ripe tomato.

  ‘No. This won’t take long. She can’t go.’

  He smiled. They were both still standing. ‘She?’

  ‘My mother. Ndege.’ Her hands were planted on her hips. Goma was small, slight of build, easily underestimated. ‘This stupid expedition of yours – the one you think I don’t know about.’

  Mposi glanced at the door, making sure he had closed it on his way in.

  ‘You’d better sit down.’

  ‘I said this won’t take long.’

  ‘Nonetheless.’ He raised a hand in the direction of the chair he reserved for visitors, then eased his plump frame into the one on his side of the desk. ‘She was under express instructions not to mention it to anyone.’

  ‘I’m her daughter. Did you think she’d be able to keep something like that from me for long?’

  ‘You were to be informed when matters were on a more stable footing.’

  ‘You mean when everyone else learned about it.’

  ‘I’m not a fool, Goma, and I do understand your feelings. But secrecy is secrecy. What else did she mention?’

  ‘There’s more?’

  ‘Please, no games.’

  After a silence, Goma said, ‘A signal, from somewhere out in deep space.’

  Mposi rubbed his forehead. He could already feel a knot of tension building behind his eyes. ‘My god.’

  ‘Some possible connection with the Trinity – with Chiku, Eunice and Dakota. I can understand why that would be of interest to her. She lost her mother – watched as she was spirited away by an alien robot. But it’s Dakota I’m interested in.’

  ‘The elephant?’

  ‘The Tantor. If you received a signal from Eunice, then maybe Dakota’s out there as well. Do I have to explain why that’s of interest to me?’

  ‘No, I think I can guess.’ Mposi had always found Goma’s scientific reports too technical to be easily digested by a non-specialist like himself, but he could skim the abstracts, get the thrust of her argument. ‘It was just a signal. It never repeated, and we’ve been listening for it again for six months.’

  ‘But you believe it was a real message, and that it was meant for us. You think it might have some connection with the Trinity.’

  ‘This is what I told your mother. In confidence.’

  ‘If you start blaming her for the leak of your little secret, you’ll have a much bigger problem on your hands.’

  ‘Goodness, Goma. That almost sounds like a threat.’

  ‘You need to understand my seriousness.’

  ‘I do. Fully.’

  ‘Then I’ll cut to the point. Whatever that message says, Ndege’s not going.’

  ‘I rather think that choice should be your mother’s.’

  ‘It isn’t, not now. I’m going in her place. I’m a quarter of her age and much stronger.’

  ‘Be that as it may, Ndege is still alive. She has also consented to join the expedition.’

  ‘Only because you gave her no choice.’

  ‘I merely pointed out that volunteering for such an expedition could be turned to her immediate advantage.’

  ‘You dangled the idea of a pardon in front of her. I thought better of you.’

  ‘It was meant with all sincerity.’ Mposi picked up the paperweight he kept on his desk – the skull of a sea otter, polished to a pebble-like glossiness. It had been sent across space, a gift from his half-brother. ‘You have a nerve, Goma, lecturing me on my treatment of Ndege. If you doubt that, ask your mother.’

  His outburst – delivered calmly enough – had an immediate and chastening effect on his visitor. She looked contrite, sad, momentarily ashamed at herself.

  ‘I just don’t want her expectations raised.’

  ‘Nor do I,’ Mposi answered softly. He put down the skull; it made a pleasingly solid thunk. ‘I would never put a false hope before your mother, not after all she’s been through. Are you serious, though – would you consider going in her place? You love this world, you love your work. You have a fine companion in Ru. Why give all of that up?’

  ‘Because I’d rather it was me than Ndege. And I’ve seen those ships of yours, swinging overhead like a pair of new moons. They’re huge. You can’t tell me there isn’t room for thousands of people on them.’

  ‘In their original design,’ Mposi answered. ‘But if one of the ships were to be refitted for a long-range expedition – and that’s still not a given – a great deal would need to be reorganised.’

  ‘I bet you could still find room for Ru.’

  Mposi could hardly believe his ears. ‘You’ve spoken to her as well?’

  ‘Out of respect for your secret, no. In fact, I haven’t spoken about it to anyone except Ndege. Does that make you happier?’

  ‘Marginally.’

  ‘But I will put it to Ru. She’ll feel the same way about Dakota. We lost the Tantors, Mposi. We lost the most beautiful, surprising thing ever to happen to us as a species. New friends – new companions. And we let them die. That’s all Ru and I have ever done – chart the decline, the tailing-off of their intelligence. But now we have a chance to recontact one of the original Tantors, or at least her offspring. Even if all we recovered was fresh genetic material, that would give us something new. Ru knows that, too. She’ll want to come with me.’

  ‘Does Ndege know of your intentions?’

  ‘I told her I’d speak to you about it.’

  ‘And did she approve? No – you don’t need to answer that. Ndege would try to protect you just as you’re trying to protect her. She wouldn’t want you to leave.’

  ‘Ultimately, though, the choice would be yours, uncle. Commit your sister to something she won’t survive, or take a chance on your niece?’

  ‘When you put it like that, it sounds so simple.’

  ‘That’s because it is. Agree to my being on that ship, uncle.’

  He felt himself on the brink of consenting. But he would not – could not – allow the decision to be made in haste. Too much was at stake. It was vastly more complicated than Goma understood.

  ‘I wished to do something good for your mother.’

  ‘You still
can. That ship won’t be ready for a while, will it?’

  He sighed, seeing where this was heading. ‘Another five years, so I’m told.’

  ‘Then that’s five years in which you can make things easier for Ndege. Are you ever going public with this?’

  ‘Some sort of limited disclosure will be required once it’s clear we’ve altered our plans for one of the ships. A year or two from now, perhaps.’

  ‘Then you can tell the world that Ndege has volunteered for the mission. Let her have that moment. Only the three of us need know that she won’t be going.’

  ‘It would be more than three of us. Your medical suitability for skipover would need to be assessed. There are no guarantees.’

  ‘I’m still more likely to cope with it than my mother.’

  ‘You place me in an unfortunate position.’

  ‘Then I’m glad you understand how it feels. Put me on the expedition and reserve a space for Ru. I won’t ask again, uncle. And my words earlier?’

  ‘Yes?’

  ‘They weren’t a threat. But if you want to think of it as a robust bargaining position, be my guest.’

  He smiled fondly, simultaneously proud and a little terrified. ‘You were wasted on science, Goma. We could have made a fine politician of you.’

  CHAPTER TWO

  In the early spring of the northern hemisphere of Occupied Mars, in the year 2640, on the evening of the day before he died, Kanu Akinya stood at a tall fretted window with his back to Swift. He had his hands behind him but not quite clasped, a slim-stemmed goblet dangling loosely from his fine-webbed fingers. It had been years since he was a true merman, but his anatomy retained traces of that phase of his life. Muscles corded his mountainous neck; his shoulders had a swimmer’s top-heavy broadness. Kanu’s mouth was small, his nose flat, his eyes large and expressive, optimised for light-gathering in conditions of low visibility. Grey now, he still wore his hair long, gathered into a pleated tail that hung halfway down his back.

  ‘Your move,’ Swift reminded him.
