“I didn’t realize he spent so much time in England,” I said. “I thought he was permanently based in America now.”

Madeleine smiled. “He comes when he can.”

“So how did you meet him?”

“The painting world’s a small one,” she said rather coolly, looking for someone else to speak to. “Nathaniel’s invited to all the openings.”

I should have left it there. Instead I asked her which other contemporary artists she and her husband knew. Lucian Freud? Damien Hirst? Tracey Emin? And where did her husband fit into the Brit art scene? Had Saatchi bought any of his work? She continued to smile but it fell far short of her eyes, and I knew I’d overstepped some invisible line in etiquette. I was supposed to revere the absent Nathaniel, not demonstrate knowledge of other artists or question Nathaniel’s close friendship with them.

It was all very childish, and I was amused at how she avoided me until Peter brought us together again. “Did Marianne tell you Jess Derbyshire’s been helping her settle in?” he asked, steering her towards me with a hand in the small of her back. “Jess has built a hoist so that Marianne can access the Internet via her mobile.”

I watched Madeleine’s expression close at the mention of Jess. “It’s fairly ramshackle,” I said. “We’ve discovered a signal near the ceiling in the back bedroom that allows me to operate my laptop underneath it. But it’s not ideal, and I wondered if you’d have any objections to my installing broadband. It’s available through the Barton Regis exchange and it would make life a lot easier. I’ve asked the agent and he says he can’t see a problem as long as I pay for it. I’ll happily leave the ADSL modem behind when I go.”

Peter placed a teasing hand on my shoulder. “It’s no good talking gobbledy-gook to Madeleine. She still uses a quill and parchment. It’s a little box,” he explained to her, “that separates voices from online connection…means you can use the phone at the same time as the computer. If Marianne’s prepared to pay for it then my advice is to give her the go-ahead immediately.” He laughed. “It’ll make that old ruin of yours more attractive to the next tenant, and it won’t cost you a thing.”

Madeleine’s smile would have frozen the balls off a brass monkey, but it wasn’t directed at Peter. It was directed at me. I had a strong sense that it was his hand on my shoulder that offended her, and not what he said.

I WAS SURPRISED, therefore, when she came to Barton House, full of smiles, the next morning. “I realized last night that I never gave you an answer to the broadband question,” she said gaily, as I opened the front door. “Goodness! Is the key working properly now? Mummy only ever used the bolts because the lock was so stiff.” She walked past me into the hall. “I paid a man to grease it but he didn’t think it would last.”

I shut the door behind her. “Jess lent me some WD-40. I give it a spray every day which seems to be doing the trick.” I gestured towards the sitting-room. “Would you like to go in here? Perhaps you’d rather be in the kitchen?”

“I don’t mind,” she said, looking around to see if I’d made any changes. I saw her eyes flicker towards the piece of wallpaper that had peeled away from its Blu-Tack and was now, courtesy of Jess, firmly reattached with paste. “Mummy was always very pukka about entertaining guests in the drawing-room. She thought it was non-U to expect her friends to put up with dirty crockery and vegetable peelings. Did you manage to light the Aga all right?”

“Jess did.”

Madeleine’s mouth thinned immediately. “I expect she made a song and dance of it.”

“No.” I opened the door to the sitting-room. “Shall we go in here?”

Despite its size and sunny aspect, the room was too dreary to qualify as a drawing-room, and I hadn’t been into it since my first day. Jess had told me it used to be full of antiques until Madeleine replaced them with junk from a second-hand furniture shop.

The carpet, a threadbare plush pile in muted pink, showed multiple evidence of dog accidents from when Lily had mastiffs of her own. According to Jess, she’d never exercised them enough, and had covered the marks with Persian rugs. Now packed away in storage, they were probably going mouldy, if the musty smell of damp in the room was any indication of their state when they were removed. The walls were worse. They hadn’t been decorated in years and the plaster was flaking above the skirting boards and beneath the coving round the ceiling. Irregular patches showed where Lily’s paintings had been.

In an effort to distract the eye, Madeleine had hung two of her husband’s originals and three Jack Vettriano prints on the inside walls-The Singing Butler, Billy Boys and Dance Me to the End of Love-but all you could see of the prints was the sunlight reflecting on their glass. I couldn’t understand why she’d put them there as Vettriano’s film-noir style sat very uncomfortably with Nathaniel’s fantasy pictures of rooted and foliage-laden buildings, and I assumed she’d bought them cheap as a job lot. It wasn’t a subject I had any intention of discussing with her, however, as our tastes were clearly different.

“What do you think of Vettriano’s work?” she asked, lowering herself to the vinyl sofa and spreading her skirt. “He’s very popular. Jack Nicholson owns three of his originals.”

“I prefer Hockney and Freud.”

“Oh, well, of course. Doesn’t everyone?”

I produced my friendliest smile. “Can I make you a coffee?”

“I couldn’t. I’ve just had one with Peter. He has an espresso machine. Have you tried it yet?”

I shook my head as I took the chair beside her. “Yesterday’s the first time I’ve been to his house. He wanted to introduce me to some of the neighbours.”

She leaned forward. “What did you think of them?”

“Very nice,” I answered. It happened to be a true reflection of my views but Madeleine wasn’t to know that. In the circumstances, I could hardly say anything else without appearing rude.

She looked pleased. “That’s a relief. I’d hate to think Jess had turned you against them.” She paused before going on in a rush. “Look, I hope you won’t take this wrongly-I know it’s none of my business-but you’ll have a happier time here if you look to the village for friends. Jess can be very peculiar if she takes a liking to someone. It’s not her fault…I’m sure it’s the result of losing her family…but she latches on to people and can’t seem to see how irritating it is.”

It was on the tip of my tongue to say it had already happened but it would have felt like a betrayal. I needed to resolve my issues with Jess face to face, not add to the gossip about her by fuelling Madeleine’s curiosity. “She helped me with a few things when I first arrived,” I said. “I was grateful. I hadn’t realized there was only one phone socket here, or that the mobile signal was so bad. That’s why I need broadband.”

But she was only interested in Jess. “Peter should have told you,” she said earnestly. “The trouble is he’s paranoid about breaking patient confidences. It’s not just the latching-on that’s a problem…it’s what she does when she thinks she’s being rejected. It’s obviously a legacy from the car accident-a need to be loved, I suppose-but it can be quite frightening if you’re not ready for it.”

I found myself staring at her in the same detached way that Jess stared at me. For no better reason than that I didn’t know how to respond.

“I expect you think I’m awful,” Madeleine went on apologetically, “but I’d hate you to find out two months down the line that I’m right. Ask anyone.”

I shifted my attention to my hands. “What am I supposed to ask them?”

“Oh dear! I’m not doing this very well. Perhaps I should have said listen. Listen to what they say.”

“About what?”

“The stalking. It starts with her turning up on the doorstep when you first arrive, then she’s in and out all the time. She usually comes with presents or offers of help, but it’s difficult to get rid of her afterwards. She plagued my poor mother for years. In the end, the only way Mummy could avoid her was by hiding upstairs every time she heard the Land Rover on the drive.”
