5:45 AM

KIT stared in fear at the Diablerie bottle on the kitchen table. But the glass had not smashed; the top had not fallen off; the double plastic bags had stayed intact. The lethal fluid remained safely inside its fragile container.

But now that Nigel and Daisy had pulled guns, they could no longer pretend to be innocent victims of the storm. As soon as the news from the laboratory got out, they would be connected with the theft of the virus.

Nigel, Daisy, and Elton might escape, but Kit was in a different position. There was no doubt who he was. Even if he escaped today, he would be a fugitive from justice for the rest of his life.

He thought furiously, trying to devise a way out.

Then, as everyone stood frozen, staring at the vicious little dark gray pistols, Nigel moved his gun a fraction of an inch, mistrustfully pointing it at Kit, and Kit was seized by inspiration.

There was still no reason why the family should suspect him, he realized. He might have been deceived by the three fugitives. His story that they were total strangers still stood up.

But how could he make that clear?

Slowly, he raised his hands in the traditional gesture of surrender.

Everyone looked at him. There was a moment when he thought the gang themselves would betray him. A frown passed over Nigel's brow. Elton looked openly startled. Daisy sneered.

Kit said, "Dad, I'm so sorry I brought these people into the house. I had no idea…"

His father gave him a long look, then nodded. "Not your fault," he said. "You can't turn strangers away in a blizzard. There was no way you could have known"- he turned and gave Nigel a look of scorching contempt-"just what kind of people they are."

Nigel got it immediately and jumped in to back up Kit's pretense. "I'm sorry to return your hospitality this way… Kit, is it? Yes… You saved our lives in the snow, now we're pointing guns at you. This old world never was fair."

Elton's expression cleared as he grasped the deception.

Nigel went on: "If your bossy sister hadn't poked her nose in, we might have left peacefully, and you would never have found out what bad people we are. But she would insist."

Daisy finally understood, and turned away with a scornful expression.

It occurred to Kit that Nigel and the gang might just kill his family. They were willing to steal a virus that would slaughter thousands, why would they hesitate to gun down the Oxenfords? It was different, of course: the notion of killing thousands with a virus was a bit abstract, whereas shooting adults and children in cold blood would be more difficult. But they might do it if they had to. They might kill Kit, too, he realized with a shudder. Fortunately, they still needed him. He knew the way to Luke's cottage and the Toyota Land Cruiser. They would never find it without him. He resolved to remind Nigel of that at the first opportunity.

"What's in that bottle is worth a lot of money, you see," Nigel finished.

To reinforce the simulation, Kit said, "What is it?"

"Never you mind," said Nigel.

Kit's mobile phone rang.

He did not know what to do. The caller was probably Hamish. There must have been some development at the Kremlin that the inside man thought Kit needed to know about. But how could he speak to Hamish without betraying himself to his family? He stood paralyzed, while everyone listened to his ring tone playing Beethoven's ninth symphony.

Nigel solved the problem. "Give me that," he said.

Kit handed over his phone, and Nigel answered it. "Yes, this is Kit," he said, in a fair imitation of a Scots accent.

The person at the other end seemed to believe him, for there was a silence while Nigel listened.

"Got it," he said. "Thanks." He hung up and pocketed the phone. "Someone wanting to warn you about three dangerous desperadoes in the neighborhood," he said. "Apparently the police are coming after them with a snowplow."

CRAIG could not figure Sophie out. One minute she was painfully shy, the next bold to the point of embarrassment. She let him put his hands inside her sweater, and even unfastened her bra when he fumbled with the hooks; and he thought he would die of pleasure when he held both her breasts in his hands-but then she refused to let him look at them in the candlelight. He got even more excited when she unbuttoned his jeans, as if she had been doing this sort of thing for years; but she did not seem to know what to do next. Craig wondered whether there was some code of behavior that he did not know about. Or was she just as inexperienced as he? She was getting better at kissing, anyway. At first she had been hesitant, as if not really sure whether she really wanted to do it; but after a couple of hours' practice she was enthusiastic.

Craig felt like a sailor in a storm. All night he had ridden waves of hope and despair, desire and disappointment, anxiety and delight. At one moment she had whispered, "You're so nice. I'm not nice. I'm vile." And then, when he kissed her again, her face was wet with tears. What are you supposed to do, he wondered, when a girl starts crying while you've got your hand inside her panties? He had started to withdraw his hand, feeling that must be what she wanted, but she grabbed his wrist and held him there. "I think you're nice," he said, but that sounded feeble, so he added: "I think you're wonderful."

Although he felt bewildered, he was also intensely happy. He had never felt so close to a girl. He was bursting with love and tenderness and joy. When he heard the noise from the kitchen, they were talking about how far to go.

She said, "Do you want to go the whole way?" Do your

"I do if you do."

Craig nodded. "I really want to."

"Have you got condoms?"

"Yes." He fumbled in his jeans pocket and took out the little packet.

"So you planned this?"

"I didn't have a plan." It was half-true: he hadn't had much of a plan. "I was hoping, though. Ever since I met you I've been thinking about, well, seeing you again, and so on. And all day today…"

"You were so persistent."

"I just wanted to be with you like this."

It was not very eloquent, but it seemed to be what she wanted to hear. "All right, then. Let's do it."

Are you sure?

"Yes. Now. Quickly."

"Good."

"Oh, my God, what's that?"

Craig had been aware of people in the kitchen below. He had vaguely heard the murmur of voices, then someone had clattered a saucepan, and he had smelled bacon. He was not sure what the time was, but it seemed early for breakfast. However, he had taken no notice, confident that no one would interrupt them here in the attic. Now the sounds could not be ignored. First he heard Grandpa shout-an unusual event in itself. Nellie started barking like a fiend; there was a scream that sounded remarkably like Craig's mother; then several male voices yelled at once.

Sophie said in a frightened voice, "Is this normal?"

"No," he replied. "They have arguments, but not shouting matches."

"What's going on?"

He hesitated. Part of him wanted to forget the noise and act as if he and Sophie were in a universe of their own, lying on the old sofa under their coats. He could have ignored an earthquake to concentrate on her soft skin and hot breath and moist lips. But another part of him felt that the interruption was not entirely unwelcome. They had done almost everything: it might even be nice to postpone the ultimate, so that there was something else to look forward to, a further delight to anticipate.

Below them, the kitchen went quiet as suddenly as it had burst into sound.

"Strange," he said.

"It's spooky."

Sophie sounded frightened, and that made up Craig's mind. He kissed her lips once more, then stood up. He pulled up his jeans and stepped across the attic to the hole in the floor. He lay down and looked through the gap in the floorboards.
