In the evening, after they’d eaten, they sat on the deck, facing out to sea, listening to music and planning the voyage’s end. Unless news from São Paulo or Lausanne reached them by morning to suggest otherwise, they’d conclude that they’d gathered all the data needed to fuel research into the mutants for the foreseeable future. They’d rejoin the expedition for a day or two, to compare notes face to face, then Grant would sail back to Sulawesi to return her hired boat. Prabir wasn’t sure yet whether he’d hitch a ride with her to Ambon. It would depend on the reception he got from Madhusree.
‘What are you going to say to her?’ Grant asked.
Prabir shook his head. ‘I don’t know. I can’t tell her the things I told you. I’m not going to poison her life with that. But I don’t want to lie to her any more. I don’t want to feed her some line about coming here to spare her from the trauma.’
Grant shot him an exasperated look. ‘Doesn’t it occur to you that that could still be true? You can have more than one reason for doing something.’
‘I know, but—’
She cut him off. ‘Don’t let this blight everything. Don’t let it rob you of the things you have a right to be proud of. Do you honestly believe that you’ve never once tried to protect her just because she’s your sister?’
Prabir replied fiercely, ‘If I haven’t, then at least I’m not a slave to my genes.’
Grant’s eyes narrowed. ‘And that matters more to you?’ For a moment Prabir thought he’d lost her, that his words were unforgivable, but then she added drily, ‘At least in a bad enough movie you could turn out to be adopted.’
He said, ‘If that’s your idea of a bad movie, you’ve had a very sheltered life.’
He reached over and stroked her face with the back of his hand. She kept her eyes on his, but said nothing. He’d acted on a barely conscious sense of rightness, half expecting to have his instinct proved utterly mistaken, but she neither encouraged nor rebuffed him. He remembered her watching him, the night they’d arrived; at the time he’d doubted it meant anything at all, but now he felt as if scales had fallen from his eyes.
He bent down and kissed her; they were sitting propped up against the wall of the cabin, it was hard to face her squarely. For a moment she was perfectly still, but then she began to respond. He ran a hand along her arm. The scent of her skin was extraordinary; inhaling it sent warmth flooding through his body. The Canadian girls in high school had smelt as bland and sexless as infants.
He slipped his hand under the back of her shirt and stroked the base of her spine, pulling her towards him, aligning their bodies. He already had an erection; he could feel his pulse where it pressed against her leg. He moved his hand to her breast. He had to fight away any image of where they were heading; he was afraid that if he pictured it he’d come at once. But he didn’t have to think, he didn’t have to plan this: they’d be carried forward by the internal logic of the act.
Grant pulled away suddenly, disentangling herself. ‘This is a bad idea. You know that.’
Prabir was confused. ‘I thought it was what you wanted!’
She opened her mouth as if to deny it, then stopped herself. She said, ‘It doesn’t work like that. I’ve been faithful to Michael for sixteen years. I’ll sit up all night and talk if you want, but I’m not going to fuck you just to make you feel better.’
Prabir stared down at the deck, his face burning with shame.
She said gently, ‘Look, I’m not angry with you. I should have stopped you sooner. Can we just forget about it?’
‘Yeah. Sure.’
He looked up. Grant smiled ruefully and implored him, ‘Don’t make a big deal out of this. We’ve been fine until now, and we can still be fine.’ She rose to her feet. ‘But I think we could both do with some rest.’ She reached down and squeezed his shoulder, then walked into the cabin.
After the lights had gone out, Prabir knelt at the edge of the deck and ejaculated into the water. He rested his head on the guard rail, suddenly cold in the breeze coming in off the sea. The images of her body faded instantly; it was obvious now that he’d never really wanted her. It had been nothing but a temporary confusion between the friendship she’d shown him in the kampung, and the fact that he hadn’t touched Felix for what seemed like a lifetime. It had never occurred to him that he might have lost the knack for celibacy, that after nine years it could take any effort at all to get through a mere three or four weeks.
