The sea was growing rougher. There was no obvious direction or pattern to the waves. Each time the Yvette rose on the swell, she’d glimpse the pass and steer back towards it; but then they’d pitch into a trough and it would corkscrew her all over the place, so that whenever she next rose, they were off course again.
Daniel raised his head a little, looked around. He caught her eye and froze for a moment, as if his memory had returned. He started rubbing his hands and ankles back and forth to gain some play. ‘Stop that!’ she shouted. But he didn’t stop. ‘Please!’ she cried. ‘Just let me get us home. Then I’ll let you free.’ But he looked at the turbulent sea and shook his head. The bottle of ketamine rolled across the deck. She picked it up; there was still a little left. She went down into the cabin for a fresh syringe, came back up to find Daniel working furiously at his wrists, getting some decent play in them now. She sucked up the last of the ketamine, plunged it into his arm. Blood bubbled on his skin. They both looked at each other for a moment, before Daniel resumed his frantic efforts to escape. Rebecca took a step back. One hand free, two hands, pulling off his gag, scrabbling at his ankles. But then his hands stopped obeying him, his movements slowed, he groaned and was out again.
She approached him warily. His wrists were free, his ankles almost so. She checked his pulse. Faint and slow, but regular enough. She retied his knots as well as she could, aware they wouldn’t hold him long. The hatches were broken. She was out of anaesthetics. She needed some other plan. Daniel’s bag was close by. She fetched it, opened it up. It had his dive equipment inside, the re-breather, wetsuit and a small tank of oxygen. She pulled out the wetsuit to make space, then added the handgun and all the lead weights she could find in the bench lockers. By the time she was finished, it was so heavy she could barely pick it up, but it still had too much air in it for her purpose, so she scooped up sea-water in a bucket and splashed it into the bag until it spilled glassily on to the deck. Then she zipped it up and lashed it to Daniel’s ankles with a coil of rope.
It was growing a fraction less dark. Night would be over soon. Back inside the bridge, rising and falling on the swell, she lined up the Yvette for the pass once more, glancing around regularly to check Daniel for signs of life. It wasn’t long before he raised his head groggily. She went out, knelt beside him, waited until he focused and looked her in the eye. ‘Listen to me,’ she told him. ‘See this rope around your ankles? It’s tied to your bag, which I’ve filled with weights. If you cause me any more trouble, I’ll throw it overboard, and it’ll take you with it. I really, really don’t want to do that. I swear I don’t. All I want to do is get us safely back to Eden. But I’ll do it if you make me. Do you understand?’
He nodded. She hurried back to the bridge. The sea was getting higher all the time; the boat kept skewing on the swell. A great wave crashed over their side; she looked around to see Daniel working again at his knots. ‘Stop it!’ she shouted, but he kept at it. She ran back out, lifted up the bag. He stopped struggling at once, nodded compliance. But then the Yvette began sliding from the crest of a swell, and kept on going. His eyes went past her; he blanched and redoubled his efforts to get free. Rebecca glanced around. The foamy crest of a freak wave towered above them, bearing down fast. The Yvette was already deep in its trough. She stared at it in horror for a moment, then back down at Daniel, struggling furiously now, helpless at her feet, bound and weighted and doomed, utterly dependent upon her. And she realised, in that one fraction of a second, that all the incriminating evidence in the world didn’t matter a damn. She threw herself down upon him, straddled her arms and legs around him, grabbed hold of a davit to pin them both to the deck, took a deep breath and held it as the wave swept them along, tipping the Yvette almost on to her side and hurtling them along with it for several seconds, so that Rebecca was certain they’d capsize. But Adam had built her for stability and safety rather than speed. The wave crashed over them and the Yvette bobbed aright, drenched and creaking but afloat, Daniel still in her arms. She buried her head into his shoulder, hugged him and began sobbing in relief.
It was a moment later that she heard the hiss. She looked around. The weighted bag had washed overboard and the rope tying it to Daniel’s ankles was paying out. It reached full length and dragged Daniel and her both against the sopping deck to the rail. She held on to him grimly, a tug-of-war in which she struggled to gain ground, but wasn’t losing either, buying him time to free his hands. Her arms began to tire. Her shoulder throbbed. The knots around his wrists and ankles had soaked and pulled tight. The Yvette tilted again. Rebecca looked up, appalled. Freak waves sometimes came in pairs. This one, if anything, was even bigger. Daniel began breathing fast and deep, packing his lungs with air. Then it crashed over them, picking them both up and sweeping them overboard. Rebecca still had hold of Daniel, but the weighted bag pulled him down and took her with him. They sank quickly; he began slipping through her fingers. She grabbed his elbow but her fingers slid down his forearm to his wrist. She tried to hold him, but he was too heavy for her and he fell away. He must have freed his hands, however, for at the last moment he grabbed her ankle, pulling her down with him, her lungs bursting for air, both of them doomed unless she got away. But before she could kick free, he simply let her go.
She swam for the surface, gasping in air the second she breached it, then looking around for Daniel, praying he’d pop up beside her; but there was no sign of him. She waited for him to resurface, riding the swell of waves, searching all around her, but in vain. She dived down, again and again, flapping her arms in hope, but it was futile in the enormous darkness. Her heart turned to lead inside her as seconds accumulated into minutes. She could still feel his grip around her ankle. She could still feel the way he’d let go.
The Yvette had righted herself. She was maybe fifty or sixty metres away, being swept towards the reef. Rebecca needed to get back to her now. The highest waves had passed, but the swell was still steep, and took real effort to negotiate, so that her injured shoulder ached wretchedly by the time she made it. She worked her way around to the stern ladder, hauled herself aboard. Pierre was banging and yelling in terror in the hold. She’d forgotten all about him. She glanced down through the broken starboard hatch. He was sitting up in a foot or so of water, having spat out his neckerchief, his wrists and ankles still tied.‘Let me out!’ he begged, when he saw her. ‘Let me out! Please. I meant no harm. I swear it.’
The waves were taking them ever closer to the reefs. She didn’t have much time. ‘Tell me what happened,’ she said.
He looked cowed, beaten. ‘It was a gift from God, Becca,’ he said. ‘Your father was just going to give it away.’
‘You sent him that email, then came back to watch.’
‘No.’
She turned and walked away. He yelled out desperately behind her: ‘I swear it, Rebecca. It was only a sudden idea to send that email. I meant to ask Lalao and Marie-Claire to watch where your father sails. From different places, you know.’
Rebecca went back. ‘Triangulation,’ she said flatly.
‘Yes. But I never even got hold of them, I swear. Nothing happened.’
‘Nothing except my father and sister dying,’ she said bitterly. ‘They were your friends. They did everything for you. How could you betray them like that?’
He had the grace to look ashamed. ‘All my women, my children. You think my life comes free? Please, Becca.’ He got on to his knees to show her his wrists bound behind him. ‘Untie me. Please.’
