10:30 PM

KIT waited in his room, impatient for everyone to settle down for the night. He needed to get away as soon as possible, but everything would be ruined if someone heard him leave, so he forced himself to linger.

He sat at the old desk in the box room. His laptop was still plugged in, to conserve the battery: he would need it later tonight. His mobile phone was in his pocket.

He had dealt with three calls to and from the Kremlin. Two had been harmless personal calls to guards, and he had let them through. The third had been a call from the Kremlin to Steepfall. Kit guessed that Steve Tremlett, having failed to reach Toni Gallo, might have wanted to let Stanley know about the problem with the phones. He had played a recorded message saying there was a fault on the line.

While he waited, he listened restlessly to the sounds of the house. He could hear Olga and Hugo having a row in the next bedroom to his, Olga firing questions and assertions like a pistol, Hugo by turns abject, pleading, persuading, bantering, and abject again. Downstairs, Luke and Lori clattered pots and crockery in the kitchen for half an hour, then the front door slammed as they left to go to their house a mile away. The children were in the barn, and Miranda and Ned had presumably gone to the guest cottage. Stanley was the last to bed. He had gone into his study, closed the door, and made a phone call—you could tell when someone was on the phone elsewhere in the house, because a "busy" light appeared on all the extensions. After a while Kit heard him climb the stairs and close his bedroom door. Olga and Hugo both went to the bathroom, and afterward they were quiet; either reconciled or exhausted. The dog, Nellie, would be in the kitchen, lying next to the Aga, the warmest place in the house.

Kit waited a little longer, giving them all a chance to go to sleep.

He felt vindicated by the family squabble earlier. Miranda's peccadillo proved that he was not the only sinner in the family. They blamed him for revealing a secret, but it was better to have these things out in the open. Why should his transgressions be blown up out of all proportion and hers discreetly hidden away? Let them be angry. He had enjoyed seeing Olga smack Hugo. My old sister packs a punch, he thought with amusement.

He wondered if he dared leave yet. He was ready. He had taken off his distinctive signet ring, and had replaced his stylish Armani wristwatch with a nondescript Swatch. He was dressed in jeans and a warm black sweater; he would carry his boots and put them on downstairs.

He stood up—then heard the back door slam. He cursed with frustration. Someone had come in—one or two of the kids, probably, raiding the fridge. He waited to hear the door again, indicating that they had left; but instead footsteps mounted the stairs.

A moment later he heard his bedroom door open. The footsteps crossed the outer room and Miranda came into the box room. She wore Wellington boots and a Barbour over her nightdress, and she was carrying a sheet and a duvet. Without speaking, she went to the sleepchair and unfolded it.

Kit was irate. "For God's sake, what do you want?"

"I'm sleeping here," she replied calmly.

"You can't!" he said, panicking.

"I don't see why not."

"You're supposed to be in the cottage."

"I've had a row with Ned, thanks to your dinnertime revelation, you sneaking little shit."

"I don't want you here!"

"I don't give a damn what you want."

Kit tried to stay calm. He watched with dismay as Miranda made up a bed on the sleepchair. How was he going to steal out of his bedroom, with her in here where she could hear everything? She was upset, she might not go to sleep for hours. And then, in the morning, she was sure to get up before he returned and notice his absence. His alibi was collapsing.

He had to go now. He would pretend to be even angrier than he really was. "Fuck you," he said. He unplugged his laptop and closed the lid. "I'm not staying here with you." He stepped into the bedroom.

"Where are you going?"

Out of her sight, he picked up his boots. "I'm going to watch TV in the drawing room."

"Keep the volume low." She slammed the door between the two rooms.

Kit went out.

He tiptoed across the dark landing and down the stairs. The woodwork creaked, but this house shifted constantly, and no one took any notice of odd noises. A faint light from the porch lamp came through a small window beside the front door and made halos around the hat stand, the newel post at the foot of the stairs, and the stack of directories on the telephone table. Nellie came out of the kitchen and stood by the door, wagging her tail, hoping with irrepressible canine optimism to be taken for a walk.

Kit sat on the stairs and put his boots on, listening for the sound of a door opening above him. This was a dangerous moment, and he felt a shiver of fear as he fumbled with his laces. People were always walking around in the middle of the night: Olga might want a drink of water, Caroline could come over from the barn looking for a headache pill, Stanley might be struck by scientiflc inspiration and go to his computer.

He tied his bootlaces and put on his black Puffa jacket. He was almost out.

If someone saw him now, he would simply go. No one would stop him. The problem would arise tomorrow. Knowing he had left, they might guess where he had gone, and his whole plan was that no one should understand what had happened.

He shoved Nellie away from the door and opened it. The house was never locked: Stanley believed that intruders were unlikely in this lonely spot, and anyway the dog was the best burglar alarm.

Kit stepped outside. It was bitterly cold, and the snow was falling heavily. He pushed Nellie's nose back inside and closed the door behind himself with a soft click.

The lights around the house were left on all night, but despite them he could hardly see the garage. The snow was several inches thick on the ground. In a minute his socks and the cuffs of his jeans were soaked. He wished he had worn Wellingtons.

His car was on the far side of the garage, a duvet of snow on its roof. He hoped it would start. He got in, putting his laptop on the passenger seat beside him, so that he could deal quickly with calls to and from the Kremlin. He turned the key in the ignition. The car coughed and spluttered but, after a few seconds, the engine turned over.

Kit hoped no one had heard it.

The snow was so heavy it was blinding. He was obliged to switch on his headlights, and pray that no one was looking out of a window.

He pulled away. The car slid alarmingly on the thick snow. He crept forward, careful not to turn the steering wheel suddenly. He coaxed the car onto the drive, maneuvered cautiously around the headland and into the woods, and followed the lane all the way to the main road.

Here the snow was not virgin. There were tire tracks in both directions. He turned north, heading away from the Kremlin, and drove in the tracks. After ten minutes he turned onto a side road that wound over hills. There were no tire tracks here, and he slowed even more, wishing he had four-wheel drive.

At last he saw a sign that read "Inverburn School of Flying." He turned into an entry. Double wire gates stood open. He drove in. His headlights picked out a hangar and a control tower.

The place appeared deserted. For a moment, Kit half-hoped the others would not show up and he could call off the whole thing. The thought of suddenly ending this terrible tension was so appealing that his spirits sank and he began to feel depressed. Pull yourself together, he thought. Tonight will be the end of all your troubles.

The hangar door stood partly open. Kit drove slowly in. There were no planes inside—the airfield operated only in the summer months—............
