Stevie slept and dreamt, not of the disintegrating city, or the dead she had known, but of food: steaming pasta rich with pesto; forbidden crusty bread, warm from the oven and dripping with butter; Cornish pasties, swollen and succulent. She woke, hungry and ashamed, to the sound of a key turning in the lock. Buchanan’s son William entered, still clad in his protective suit. The room seemed to shrink around him. He showed her Hope’s gun.
‘Any crap, and I’ll shoot you.’
Stevie sat up in bed and smoothed her hair with her fingertips. Perhaps she was adjusting to the way the mask distorted William’s voice, because this time she could make out his accent, a public-school drawl. His pronunciation should have been at odds with the gangster-speak, but working on the edges of the media had brought Stevie into contact with enough posh people for her to know that the upper classes were not necessarily strangers to an uppercut.
Stevie swung her feet on to the floor. ‘Let me go, and I promise to walk away. No one cares any more about how or why Simon died, or whether Fibrosyop acted unethically. I’m sure your father had his reasons for what he did.’ She let a tear roll down her cheek. ‘We need to look forwards, not back, if we’re to survive.’
William Buchanan gestured towards the door with the gun.
‘That’s exactly what we are doing.’
Stevie shifted to the edge of the bed, ready to get to her feet if it looked like William might hit her.
‘No, it’s not. I don’t know what your father’s told you, but he’s obsessed with covering up his involvement in Simon’s murder.’
‘You’re the only one who’s obsessed with Simon. Everyone else is concentrating on staying alive.’ William paused. ‘Except my dad, I suppose.’
Stevie leant forward. ‘And what is your father concentrating on?’
‘Finding a cure. That’s why he was so keen to get you to come here. I thought you would have worked that out for yourself by now.’
And in that moment Stevie realised her true worth to the chemist.
Buchanan’s lab was in a large room punctuated by rows of workbenches. Its windows were high and small, but they offered a glimpse of summer sky, Marian blue and dotted with white clouds so perfect they might have been painted on silk. Stevie thought of the metal railings guarding the building, the unscaleable height of them.
Buchanan had also donned a protective suit and mask. Panic fluttered in Stevie’s chest. She asked, ‘What are you going to do to me?’
‘Just a few tests.’ The mask obscured Buchanan’s face, but she thought that perhaps he was smiling. ‘Nothing to worry about.’
Stevie took a step backwards but William reached out and gripped her by the elbow. Hope’s gun was in his other hand. She wondered if she should make a lunge for it, but the barrel was pointing at her forehead and she caught a glimpse of its tunnelling depths, the blackness waiting for her there.
The chemist glanced at the expression on her face and said, ‘William, the gun is persuasion enough.’ He turned his attention back to Stevie. ‘It’s been a stressful time.’ He might have been talking about a threatened redundancy that had failed to materialise. ‘I didn’t get the opportunity to ask how you’ve been, healthwise that is, since we last met.’
Stevie pulled herself free of William’s grip. He let her go, but stayed close enough for her to feel his presence, the heat of his body inside the suit. She said, ‘Can I have a glass of water, please?’ She wasn’t thirsty, but it seemed important to make her jailers do something for her. Buchanan turned on a tap at the sink built into the workstation next to him. He let the water run for a moment, then filled a small paper cone and handed it to her. Stevie took a sip. ‘I’ve been fine.’
Buchanan nodded. ‘Have you come into contact with many sufferers?’
The laboratory smelt drily of chemicals. Stevie had imagined that the chemist’s quarters would resemble the labs in cosmetic commercials, shiny and wipe-clean, but the room had been caught up in the chaos of the outside world. Its countertops were littered with the detritus of Buchanan’s work: flasks crusted with mysterious crystals, reams of paper, evil-looking Bunsen burners and abandoned Petri dishes, some of them clouded and staring, like sightless eyes.
‘You can’t be out there and not come into contact with people who have the sweats.’ She took a step to the left and looked at William, including him in their conversation. ‘Ask your son.’
‘I’m asking you. How close?’
‘Close.’
‘Close enough to touch?’
‘Yes.’
‘To share a meal?’
Stevie remembered the tea and biscuits Iqbal had given her.
‘Yes.’
‘To have sexual intercourse with?’
She drank the last of the water, crushed the paper cone and dropped it on the floor.
‘That’s none of your business.’
William said, ‘Answer the question.’ But Stevie heard the discomfort in his voice, and hugged it to herself, like a prison shank.
‘Once, with someone who subsequently died of the sweats.’
It felt like a betrayal to describe Iqbal’s death so casually.
‘How soon afterwards did the other person die?’
‘I’m not sure.’ She let her eyes run over a weird arrangement of glass pipes and beakers, like the skyline of some futuristic city. ‘I left, and when I came back, he was dead. Two days at the most.’
Buchanan nodded as if she had given the right answer. He slid open a drawer, took something out and started busying himself with it. His heavy gloves hid the object from view.
‘I’m grateful to you for seeking us out, Ms Flint. You saved us a lot of effort.’ He looked directly at her. ‘Come here, please.’
Stevie glanced at William, at the revolver in his hand, and wondered how good a grip his gloves allowed him. She walked towards Buchanan, aware of the gun following her, and saw the camp bed, low on the ground behind the workstation. She saw too what the chemist was holding in his hands: a syringe.
‘I’m not the only survivor.’ Her voice wavered. ‘There are lots of people out there.’
Buchanan said, ‘Perhaps, but you’re the only one who came to us. Don’t worry. I’ve no intention of harming you. I just need to find out what it is that makes you immune. Roll up your sleeve and lie down on the bed, please. It’s a little difficult to be dexterous, gloved up like this, so I’m going to ask you to stay very still.’
Stevie wrapped her arms around herself.
‘What are you planning to do to me?’
‘Nothing drastic. I’m going to take a blood sample.’ The pale face inside the helmet smiled. ‘I’m afraid I’m a little rusty at this so you’ll have to bear with me. When we were students, nurses used to joke, “Just a little prick with a needle,” whenever Simon or I attempted to give an injection. I’m not sure I’ve improved much since then.’
Stevie hugged her body tighter. Instinct warned her that once she was on the bed she would be lost. She said, ‘It was never about the children for you, was it? You wanted the glory of making a medical breakthrough. When you discovered you’d made a mistake and the treatment was no good, instead of coming clean you faked the results.’ She turned to face Buchanan’s son. ‘You must have lost people too, William. We all have. Everyone is grieving, except for your father. He thinks the sweats are an opportunity to turn himself into a god, but he’ll screw this up, just like he screwed up before.’
‘You talk too much.’ William pushed Stevie against the workbench and pinned her there with his body. Stevie stamped on his toes but he was wearing heavy work boots and her feet made no impact. William peeled her left arm free and shoved her sleeve up beyond her elbow. A cough rumbled in his chest. Stevie felt it shudder against her spine. She kept her eyes on his father.
‘You killed Simon to protect your work.’ William’s weight was forcing the air out of her, and her words came in gasps. ‘But your work was shit, it wasn’t worth protecting.’
The chemist swabbed the crease on the inside of her elbow, tapped it gently to raise a vein and tightened a tourniquet around her arm.
‘You talk about Simon as if he was uncorruptible but he was as flawed as the rest of us. I told you he always came round in the end.’ Buchanan looked up and his eyes met hers, still blue behind the protective visor. ‘This time was no exception.’
The needle pierced Stevie’s flesh and she gasped. William’s groin was pressed against her rear. Stevie felt his excitement, and bile rose warm in her throat. She swallowed and said, ‘I promise to co-operate, if you tell me what happened.’
The chemist withdrew the syringe, leaving a small valve attached to her vein. He inserted a tube into it, and then looked beyond her, at his son. ‘William, can you help Ms Flint on to the couch please?’
Stevie said, ‘I’ll do it myself.’
The chemist nodded and William let go, but Stevie had already felt a tremble in his body that might have been arousal, or something else. She sat on the camp bed. A small, clear plastic bag was resting on top of its mattress. Buchanan attached the tube in her arm to it. He said, ‘Simon always had an impulsive side. When he was young he had the energy to work as hard as he played, but he’d become careless, one might even say, lazy. No amount of brilliance can compensate for complacency. Simon was a good surgeon, but he was a shade short of brilliant.’
The blood was leaving her arm, darker than Stevie had anticipated. It was as if she could see her strength deserting her. But she could also see the perspiration behind William’s mask and knew that it was vital to keep the chemist’s attention focused on her. She asked, ‘How much blood are you going to take?’
‘An armful,’ the chemist joked. ‘Don’t worry, we’re not vampires. We won’t drain you.’
William made a small spluttering sound. He said, ‘This bloody suit is too warm.’
‘It’s necessary.’ Buchanan squatted in front of Stevie, his bedside manner at odds with the gun still pointing at her head. He said, ‘Clench and unclench your hand. It will make the blood come quicker.’
Stevie made a fist and released it, made a fist and released it; fist, star, fist, star, fist, star. Her arm ached. She said, ‘Why did you poison Simon?’
She had expected a denial, but the chemist asked, ‘Why do you care so much?’
‘Because I loved him.’ It was the first time Stevie had said it out loud, and the words surprised her.
The chemist glanced at his son.
‘There is a theory that believing yourself to be in love can subtly alter the chemical compounds of the body.’ He looked at Stevie. ‘It’s possible that your love for Simon is a factor in why you’re still alive.’
William had been staring at her face, as if trying to decide whether he would prefer to kiss Stevie or shoot her, but he glanced at his father.
‘If she fell out of love, would she lose her immunity?’
‘That would be an extreme reaction, but who knows, it might be possible.’ Alexander Buchanan’s voice was amused, as if he had long come to terms with his son being a fool. He touched the bag, warm with her blood, and looked at Stevie. ‘Are you willing to risk destroying Simon’s spell?’
Stevie nodded. William’s plastic visor was beginning to mist up. She wondered if Buchanan had noticed. Harvesting her blood had given the chemist a boost of energy. His face beamed inside his helmet, making him look like a spaceman who had managed to slip into the orbit of a planet he had feared he would never reach.
‘Simon never dated what my mother would have termed his social equals. He preferred the kind of girl who would be impressed by the fact that he was a surgeon.’
Stevie asked, ‘You didn’t find it impressive?’
William said, ‘Dad thinks a sawbones is one step up from a car mechanic.’
‘Harsh but true.’ There was a dreaminess to the chemist’s voice. He glanced at his son and Stevie wondered how he could miss the fog of moisture, the glistering skin. He said, ‘Simon was a good surgeon, but outside the operating theatre he left most of the work to John Ahumibe and me. He was willing to take a third of the credit, but was too busy having a good time to do a third of the work. Perhaps that was why our arrangement was a success. I liked being in control and he was happy to leave me to it.’
Stevie looked at the bag, almost full of her blood.
‘Shouldn’t you unhook me?’
Buchanan said, ‘In a moment.’
William coughed again. ‘Forget the bedtime story.’ Buchanan smiled at his son. ‘Aren’t you curious to discover whether the truth about Simon will have an effect on Ms Flint’s health?’
William said, ‘I don’t see what difference it makes, given what comes next.’
Stevie asked, ‘What comes next?’
Buchanan’s voice was soothing. ‘Nothing you need worry about.’ He slid the needle from Stevie’s arm and passed her a pad of cotton wool and a plaster. ‘Here, hold this over the puncture.’ The chemist lifted the bag of blood and looked at it. ‘We should offer you a cup of sweet tea and a biscuit, but this is the best I can do under the circumstances.’ He reached into the pocket of his overalls and tossed her a cereal bar. ‘Stay still until you get your strength back.’
Stevie glanced at William. His shoulders had lost their bold stretch. He was looking at the floor and she thought she could hear the sound of his breathing. Her appetite had deserted her, but Stevie unwrapped the paper, peeling it slowly, the way Joanie had taught her would hold an audience’s attention. She took a bite, chewed and swallowed.
‘Tell me what happened to Simon, and I promise to stay as still as a mouse.’
William said, ‘Mice aren’t still.’
‘As still as a stone,’ Stevie said.
William sank on to the bed beside her and took her hand in his gloved one.
‘Stone dead.’
Buchanan said, ‘Leave her alone, William.’ But his son stayed where he was. The chemist hesitated, as if considering whether to press his point, but then he looked at Stevie and said, ‘I would have refined the formula before Simon noticed anything was amiss, but we had a setback. A child died.’ He shrugged his shoulders. ‘Sick children do occasionally die, but the girl’s family took it badly. Her father confronted Simon.’
Stevie took another bite of the cereal bar. William’s hand trembled in hers. Dr Ahumibe had said the sweats could be on you for days before they hit home, or they could fell you in an hour or two. She said, ‘I’m assuming the parent was Melvin Summers.’
‘You’ve done your homework.’
‘I met him. His daughter’s death killed his wife and destroyed his life.’
‘If you met him, then you’ll know that Mr Summers is . . .’ Buchanan hesitated, as if something had just occurred to him. He raised an eyebrow and asked, ‘Is or was?’
‘I don’t know.’
‘. . . is, or was, an unstable alcoholic. I doubt very much whether Summers would have managed to muster the self-control to put together a convincing case, but somehow he ruffled Simon’s complacency enough to inspire him to re-examine the original research results.’
Stevie said, ‘So perhaps he wasn’t as lazy as you thought?’
The chemist shrugged. ‘On the contrary, Simon proved he was a lazy thinker. He went into a blue funk and threatened to down tools.’
‘Down scalpel,’ William muttered.
Buchanan threw his son an irritated glance, and Stevie realised that the chemist was building towards his punchline, the revelation that would show she had been wrong about Simon. She prompted him, ‘But . . .?’
Buchanan snorted. ‘. . . but as usual Simon didn’t consider the consequences. We had borrowed from our sponsors to set up Fibrosyop. If we called the treatment into question, not only would we have been bankrupt, but our professional reputations would have been destroyed. Worse than that, if it could be shown that we had knowingly continued, after we’d realised the treatment was compromised, we might well have faced criminal prosecution and prison.’
Stevie said, ‘But Simon didn’t realise that the treatment was no good until Summers alerted him. You and Ahumibe had already discovered it was useless and decided not to tell Simon because you knew he would call a halt to the operations.’
Buchanan put his head on one side. It was a coquettish gesture, sinister combined with the protective suit and headgear.
‘Simon should have worked it out. He would have, if he’d been doing his job properly.’
William looked up at his father. ‘You killed him. End of story. Who cares?’
‘Ms Flint cares,’ Buchanan said, softly enunciating the words, as if explaining an obvious fact to an imbecile. ‘Because she loved him, which is rather beautiful considering all the destruction going on around us. I loved Simon too.’
William said, ‘Fuck Uncle Simon.’ He got to his feet, stood behind Stevie and lifted the bag of blood from the bed. ‘Shouldn’t this be in a fridge or something?’
Buchanan whispered, ‘Careful, William.’
His son flopped the blood bag back on to the mattress. A soft red-black jewel that reminded Stevie of sea urchins she had sometimes seen attached to rocks at the bottom of cliffs.
William remained standing behind her. The back of Stevie’s skull, the bit she thought might make a good target, tingled, but she asked, ‘What did Simon do, after you pointed out the consequences of coming clean?’
Alexander Buchanan’s laugh was so abrupt that Stevie suddenly wondered if he had dipped into his chemical supplies.
‘He tried to buy himself out of Fibrosyop. God knows where Simon got the money from, but he presented me with what he referred to as “the first instalment”, in cash, as if actual notes would be more persuasive than the promise of a funds transfer.’
Stevie said, ‘He borrowed it from Hope Black. That’s why she was at his apartment the day William went there looking for me. She wanted her money back.’
William muttered, ‘I didn’t see the signs on her until she was on the ground.’ He stroked Stevie’s head. ‘I was wearing gloves, but I was in the same room. I breathed the same air.’ He looked at his father. ‘You were working on the vaccine.’
William’s touch made the hairs on the back of Stevie’s neck rise.
Buchanan said, ‘Simon took holiday leave. I thought he might bolt, so I asked William to keep an eye on him.’
Stevie slowly turned her body and looked at William. The tremble in his gun hand echoed the flutter in her stomach. She said, ‘You and your father were close, even before the sweats.’
‘We’ve had our differences, but blood is thicker than water. Uncle Simon was scared. You could see it in the way he walked. He kept looking over his shoulder. I didn’t bother to hide myself. I thought, let him see me. Let him be scared.’
‘I would have preferred a little more subtlety, but never mind.’ Buchanan glanced at the clock on the laboratory wall and then back at Stevie. ‘I think we’ll give it another minute before we move you. We don’t want you fainting on us.’ He leant against the worktop. If it wasn’t for his protective mask and overalls he might have looked like a man at a party, shooting the breeze over a few beers. ‘What really hurt was Simon’s lack of faith. We’d known each other since we were boys. I’d already explained that all I needed was a little time. I was so close to perfecting the formula. I dreamt about it every night.’
Stevie said, ‘You told me that Simon had come round to your way of thinking, but he hadn’t, had he?’
‘You’re wrong. After I refused to let him off the hook by buying himself out, Simon agreed to allow me three more months to work on the formula. He also agreed to undertake the operations we already had scheduled. If you really knew him, then you’d know that was the way it always went with Simon, a compromise, which was generally followed by another compromise, until finally he was convinced that whatever it was he’d initially disagreed with had been his idea all along.’
‘But you killed him?’
‘Yes.’ Buchanan’s ebullience left him. ‘Yes, I’m afraid I was forced to.’
William said, ‘This fucking suit is suffocating me.’
His free hand went to his protective helmet. Buchanan snapped, ‘Keep that on.’ But William pulled it free and Stevie saw his face close up for the first time. His hair and eyes were the same watery pale as his father’s, but his cheeks were flushed scarlet, his skin drenched in sweat.
Buchanan said, ‘Put your mask on.’
‘What’s the point?’ William held out a hand to his father, but Buchanan took a swift step backwards.
‘We need to get you into isolation.’
‘You won’t leave me again, will you, Dad?’
William’s gun hand shuddered. It was the moment Stevie had been waiting for. She grabbed the bag of blood from the bed, slammed it into William’s face and threw herself on to the floor. The plastic split on impact and her blood arced in a spray around the room, splattering all three of them. Stevie smelt herself, rich and iron, tasted her life-force sharp on her lips. The gun rattled on to the laboratory’s tiled floor. She wiped her eyes and scrambled to where it had landed.
Stevie expected Buchanan to race her, but there was no hand at her heels, no harsh breath or panicked shouts, just the sound of William groaning. She seized the gun, spun on to her back, and pointed the muzzle in front of her, ready to shoot whichever of the Buchanans came at her first.
