The top of the pedestal desk was tidy, and Kit could not see a card or mything that might contain one: just a small stack of files, a pencil jar, and a book entitled Seventh Report of the International Committee on Taxonomy of Viruses.

He started opening the drawers. His breath came fast and he felt his heartbeat speed up. But if he were caught, what would they do-call the police? He told himself he had nothing to lose, and carried on; but his hands were unsteady.

His father had been using this desk for thirty years, and the accumulation of useless objects was staggering: souvenir key rings, dried-up pens, an old-fashioned printing calculator, stationery with out-of-date phone codes, ink bottles, manuals for obsolete software-how long was it since anyone had used PlanPerfect? But there was no smart card.

Kit left the room. No one had seen him go in, and no one saw him go out.

He went quietly up the stairs. His father was not an untidy man, and rarely lost things: he would not have carelessly left his wallet in some unlikely place such as the boot cupboard. The only remaining possibility was the bedroom.

Kit went inside and closed the door.

His mother's presence was gradually disappearing. Last time he was here, her possessions were still scattered around: a leather writing case, a silver brush set that had belonged to her mother, a photograph of Stanley in an antique frame. Those had gone. But the curtains and the upholstery were the same, done in a bold blue-and-white fabric that was typical of his mother's dramatic taste.

On either side of the bed were a pair of Victorian commode chests made of heavy mahogany, used as bedside tables. His father had always slept on the right of the big double bed. Kit opened the drawers on that side. He found a flashlight, presumably for power cuts, and a volume of Proust, presumably for insomnia. He checked the drawers on his mother's side of the bed, but they were empty.

The suite was arranged as three rooms: first the bedroom, then the dressing room, then the bathroom. Kit went into the dressing room, a square space lined with closets, some painted white, some with mirrored doors. Outside it was twilight, but he could see well enough for what he needed to do, so he did not switch on the lights.

He opened the door of his father's suit cupboard. There on a hanger was the jacket of the suit Stanley was wearing today. Kit reached into the inside pocket and drew out a large black leather wallet, old and worn. It contained a small wad of banknotes and a row of plastic cards. One was a smart card for the Kremlin.

"Bingo," Kit said softly.

The bedroom door opened.

Kit had not closed the door to the dressing room, and he was able to look through the doorway and see his sister Miranda step into the bedroom, carrying an orange plastic laundry basket.

Kit was in her line of sight, standing at the open door of the suit cupboard, but she did not immediately spot him in the twilight, and he quickly moved behind the dressing-room door. If he peeked around the side of the door, he could see her reflected in the big mirror on the bedroom wall.

She switched the lights on and began to strip the bed. She and Olga were obviously doing some of Lori's chores. Kit decided he would just have to wait.

He suffered a moment of self-dislike. Here he was, acting like an intruder in the house of his family. He was stealing from his father and hiding from his sister. How had it got like this?

He knew the answer. His father had let him down. Just when he needed help, Stanley had said no. That was the cause of everything.

Well, he would leave them all behind. He would not even tell them where he was going. He would make a new life in a different country. He would disappear into the small-town routine of Lucca, eating tomatoes and pasta, drinking Tuscan wine, playing pinochle for low stakes in the evenings. He would be like a background figure in a big painting, the passerby who does not look at the dying martyr. He would be at peace.

Miranda began to make up the bed with fresh sheets, and at that moment Hugo came in.

He had changed into a red pullover and green corduroy trousers, and he looked like a Christmas elf. He closed the door behind him. Kit frowned. Did Hugo have secrets to discuss with his wife's sister?

Miranda said, "Hugo, what do you want?" She sounded wary.

Hugo gave her a conspiratorial grin, but he said, "I just thought I'd give you a hand." He went to the opposite side of the bed and started tucking in the sheet.

Kit was standing behind the dressing-room door with his father's wallet in one hand and a smart card for the Kremlin in the other, but he could not move without risking discovery.

Miranda tossed a clean pillowcase across the bed. "Here," she said.

Hugo stuffed a pillow into it. Together they arranged the bedcover. "It seems ages since we've seen you," Hugo said. "I miss you."

"Don't talk rubbish," Miranda said coolly.

Kit was puzzled but fascinated. What was going on here?

Miranda smoothed the cover. Hugo came around the end of the bed. She picked up her laundry basket and held it in front of her like a shield. Hugo gave his impish grin and said, "How about a kiss, for old times' sake?"

Kit was mystified. What old times was Hugo talking about? He had been married to Olga for nearly twenty years. Had he kissed Miranda when she was fourteen?

"Stop that, right now," Miranda said firmly.

Hugo grasped the laundry basket and pushed. The backs of Miranda's legs came up against the edge of the bed. Involuntarily, she sat down. She released the basket and used her hands to balance herself. Hugo tossed the basket aside, bent over her, and pushed her back, kneeling on the bed with his legs either side of her. Kit was flabbergasted. He had guessed that Hugo might be something of a Lothario, just from his generally flirtatious manner with attractive women; but he had never imagined him with Miranda.

Hugo pushed up her loose, pleated skirt. She had heavy hips and thighs. She was wearing lacy black knickers and a garter belt, and for Kit this was the most astonishing revelation yet.

"Get off me now," she said.

Kit did not know what to do. This was none of his business, so he was not inclined to interfere; but he could hardly stand here and watch. Even if he turned away, he could not help hearing what was going on. Could he sneak past them while they were wrestling? No, the room was too small. He remembered the panel at the back of the closet that led to the attic, but he could not get to the closet without risking being seen. In the end he just stood paralyzed, looking on.

"Just a quickie," Hugo said. "No one will know."

Miranda drew back her right arm and swung at Hugo's face, hitting him square on the cheek with a mighty slap. Then she lifted her knee sharply, making contact somewhere in the area of his groin. She twisted, threw him off, and jumped to her feet.

Hugo remained lying on the bed. "That hurt!" he protested.

"Good," she said. "Now listen to me. Never do anything like that again."

He zipped his fly and stood up. "Why not? What will you do-tell Ned?"

"I ought to tell him, but I haven't got the courage. I slept with you once, when I was lonely and depressed, and I've regretted it bitterly ever since."

So that was it, Kit thought-Miranda slept with Olga's husband. He was shocked. He was not surprised by Hugo's behavior-shagging the wife's sister on the side was the kind of cozy setup many men would like. But Miranda was prissily moral about such things. Kit would have said that she would not sleep with anyone's husband, let alone her sister's.

Miranda went on: "It was the most shameful thing I've done in my life, and I don't want Ned to find out about it, ever."

"So what are you threatening to do? Tell Olga?"
