It posed even more of a problem for Elizabeth than the letters. It appeared to be written in Greek script. She looked through it, puzzled. If it had belonged to a foreigner, someone unconnected with her family, what was it doing with this small parcel of her grandfather’s belongings? She slipped it into the pocket of her skirt and tied the rest of the papers back into their bundle.

Her mother was reading a book in the sitting room.

Elizabeth introduced the subject with a small subterfuge. “I couldn’t find the diary I was looking for. It had an old address in it from years ago. When I moved flats you let me leave a lot of stuff up there, do you remember?”

“Yes I do. I wish you’d get rid of some of it.”

“I will. While I was looking for the diary I came across a little packet of what must have been your father’s papers.”

“I thought they’d all been thrown away. There used to be a whole lot of them, but they got lost when I moved house.”

“What sort of things were they?”

“There were boxes full of notebooks that he’d kept from the time he first went to France. I think there were twenty or thirty of them. But I couldn’t understand them because they were in some sort of code.”

“There’s one up there in the attic. It looks as though it’s written in Greek.”

“That’s it,” said Françoise, putting down her sewing. “There were lots more. I always thought that if he’d wanted anyone to understand them he would have written them in plain English.”

“What was he like, your father?”

Françoise sat up in her armchair, a slight flush colouring her cheeks. “I wish you could have known him. He would have loved you. I wish he could just once have seen you and stroked your face.”

The following Saturday Elizabeth went down into the Underground station and sat on a train as it hurtled, clanked, and rolled its electric way along the bed of the pipe inserted through the glutinous clay beneath the city. At Stratford she emerged into the winter daylight and took a bus onward. She cursed the glistening Swedish sedan, which had refused to start.

Bob and Irene’s house was in a square with half a dozen naked plane trees on a plot of grass behind iron railings. At one end was a sandpit with a red-and-orange construction for children’s climbing games, its gaudy surfaces sprayed with words formed from scripts known only to the sprayer. To Elizabeth they looked like angry warnings from a fundamentalist scripture. It was too cold for children to be playing in the garden, but a woman with a woollen scarf round her head was being dragged over the sparse and muddy green by a thin alsatian, which stopped and crouched heavily at the sandpit.

Elizabeth hurried to the house and pressed the bell. She saw the top of Irene’s head as she bent to restrain her barking terrier in the half-open door. With threats and cajolings to the dog, and reassurances to Elizabeth, Irene managed to clear enough room for them both to get into the hallway and for her to close the door after them.

They went into the sitting room at the front of the house and Elizabeth sat down while Irene went to make tea. The room had dark brown wallpaper, though most of it was concealed by pictures and shelves that contained glass cases with stuffed birds and collections of china cups and saucers. There were two tailor’s dummies, one dressed in a nineteenth-century purple velvet dress, the other draped and trailed over its otherwise naked torso with antique lace. There were a number of small tables about the room with brass curios and figures on them.

“I hope Bob doesn’t mind me using him like a reference library,” said Elizabeth as Irene returned with the tea.

“I shouldn’t think so,” said Irene. “He’s probably pleased to be asked. Were those books helpful?”

“Yes, they were. I told you about the memorial I saw, didn’t I? The thing is I’ve become obsessed by the subject now and I want to know more. I’vefou nd this notebook of my grandfather’s–at least I think it’s my grandfather’s, it was in with some of his things. It’s written in a language I don’t understand and I wondered if Bob might know, what with his archaeology and everything.”

“Egyptian hieroglyphics and all that?”

“Well, it’s not Egyptian, but–“

“I know what you mean. He certainly used to know a lot about languages. He’s done courses on them. I don’t think he speaks any, but he’d probably recognize what it was, especially if it’s an old one. Not very interested in the modern world, Bob. I gave him one of them record sets so he could learn French for our holidays one year and he never opened it.”

When Bob was persuaded at Irene’s third attempt to come in from the garden, he shook hands with Elizabeth and poured himself a cup of tea. She told him about her visit to France and he nodded his head, sipping noisily, as he listened. He was shorter than his wife, with a bald skull and round tortoiseshell glasses. While she talked he rested his head on one side and occasionally scraped his chin on his upraised shoulder. Once she had explained the reason for her second visit his movements became wakeful and eager.

“Can I have a look at the offending article?” he said, holding out his hand. Elizabeth passed over the notebook, guiltily, not sure of the propriety of allowing something her grandfather had written so many years ago to come under the scrutiny of this strange little man.

“I see,” he said, rasping through the pages like a bank clerk telling notes. Elizabeth feared that the dry old paper would crack. “Wrote a lot, didn’t he? Have you got any more of these?”

“No, this is the only one left.”

“I think we’ll have to go through to my study. We’ll be back in a jiff, Irene.” He stood up quickly and beckoned Elizabeth to follow him along the dark hallway to a room at the back of the house overlooking the garden where the last of the afternoon sun had drained away to leave only the black shapes of a wheelbarrow and a damp bonfire down by the wooden fence.

“I brought back those books you lent me.” said Elizabeth.

“Thank you. Just leave them on the side there. I’ll shelve them directly I’ve finished this.”

Bob made a number of sucking and humming noises as he snapped the dry pages back and forth. “I’ve got an idea what this is about,” he murmured. “I’ve got an idea… ” He went and pulled a book from one of the shelves that filled the room from floor to ceiling. They were arranged alphabetically, with punched marker tape stuck on at intervals to announce the change of subject. Bob sat down again in a deep leather armchair; Elizabeth, at his invitation, was in the wooden chair at the desk.

“… but on the other hand, it doesn’t quite add up.” Bob put the notebook down on his lap. He pushed his glasses up on to his forehead and rubbed his eyes.

“Why do you really need to know what all this means?”

Elizabeth smiled sadly and shook her head. “I don’t know, I really don’t. It’s just a whim, really, a vague idea I had that it might explain something. But I don’t suppose there’s anything interesting in it. It’s probably just domestic lists, or records of things he’s supposed to be doing.”

“Probably,” said Bob. “You know you could have it looked at by an expert if you want. If you took it to a museum or a university department with someone who specializes in this kind of thing.”

“I wouldn’t want to trouble them with it if it’s so trivial. Couldn’t you do it for me?”

“I might be able to. It depends how much is private code. For instance, suppose you kept a diary and you referred to Irene in it as Queen Bess, shall we say. Someone might get as far as decoding the words Queen Bess, but they’d still be none the wiser, would they?”

“I suppose not. I don’t want you to spend too much time on it, Bob. Why not just–“

“No, no, it would interest me. I’d like to work it out. The script is not of the language it’s written in, I can tell you that. This is Greek script, but the words are not Greek. I think the words themselves are of a mixed language, perhaps with some private terms thrown in.”

“You mean the original language may not even be English?”

“Exactly. When they decoded Linear B they spent years thinking they were trying to decode Greek, but they weren’t. Not Attic Greek at any rate. Once they’d got that sorted out, it fell into place. Not that this is as difficult as Linear B, I can assure you.”

Elizabeth smiled. “How do you know so much about these things?”

“I had to do something to keep up with Irene. She was making all the money in the days when business was good. I just had my job at the works here. I did some studying in my spare time. It’s surprising what you can learn if you just spend some time reading. I’ll tell you what. If I can’t sort it out within two weeks, you take it to someone else.”

“Are you sure you don’t mind?”

“No. I’ll enjoy it. I like a challenge.”

There was a call from Stuart, the man she had met at Lindsay’s house. Elizabeth was surprised but not displeased to hear from him. He asked her to go out to dinner and she agreed. There was always a small feeling of guilt on her part when she went out with other men. No amount of rationalization about how “unfaithful” Robert was to her could take it away, though it never stopped her going. They went to a Chinese restaurant which Stuart insisted was of a more authentic kind than could usually be found in England. He had worked for a year in Hong Kong and had learned some Chinese there. He ordered half a dozen dishes and said a few words in Mandarin, which the waiter made a show of understanding. Elizabeth listened with interest as he explained each dish. They had the same gluelike consistency she was familiar with from Paddington takeaways, but Stuart was adamant that they were the real thing. She wished they could have wine instead of tea.

He asked if she would like to go back to his flat afterward. It was in a mansion block in St. John’s Wood, not far from the restaurant. Elizabeth was intrigued by him and curious to see what sort of place he lived in. Her eyes moved quickly over the woodblock flooring, the tasteful rugs, the loaded bookshelves. There were only three pictures on the pale gray walls, but all of them were elegant and suitable-somewhere between art and decoration. As she drank coffee, he went over to a grand piano and switched on a redshaded light beside it.

“Will you play something?” she said.

“I’m very out of practice.”

He took some persuading, but eventually rubbed his hands together and sat down.

He played a piece that was vaguely familiar to Elizabeth; it had a fragile tune whose effectiveness depended on no more than two or three notes. The way he played it, however, very gently but with subtle timing, was touchingly good. Even as she heard it, Elizabeth felt that the little phrase would stay with her.

“Ravel,” he said when he had finished. “Lovely, isn’t it?” He talked to her about Ravel and Satie and compared them to Gershwin. Elizabeth, who had thought of them as quite different kinds of composers, was impressed.

It was midnight when she finally rang for a taxi. She went downstairs happily humming the tune he had played. On the way home she had treacherous thoughts about Robert. She always told him that he made her unhappy by not leaving Jane; she promised him he would be happier with her. As far as she knew she was passionately sincere in all her protestations. However, she conceded, as the taxi crossed the Edgware Road, it was just possible that she had chosen someone unobtainable for that very reason: that he did not threaten her independence.
