If you repeat a lie often enough people start to believe it-it’s a truism that’s seared into the brains of tyrants and spin doctors-but of all Madeleine’s lies, the most pernicious was her use of “Mummy.” She used it to paint a picture of innocent love that didn’t exist, and I was amazed at how many people found it charming. Most of those who condemned Jess as unnatural for hanging pictures of her dead family on her walls never questioned whether Madeleine’s relationship with Lily was healthy and close.

“But Lily was neglected, Madeleine. As far as I can make out, she lived here for seven weeks in the most appalling conditions until Jess found her half-dead beside the fishpond. Peter went away…the surgery safety net didn’t work…the neighbours weren’t interested…and you stayed as far away as possible.” I took out another cigarette and rolled it between my fingers. “Or claim you did.”

“What’s that supposed to mean?” she demanded.

“Only that I find it hard to believe you didn’t keep tabs on what was going on.” I tucked the cigarette in my mouth and lit it. “Weren’t you and Lily close? You always call her ‘Mummy.’ The only other middle-aged woman I know who does that phones her mother every day and visits at least once a week.”

Her eyes narrowed to unattractive slits at being called middle-aged but she chose to ignore it. “Of course I phoned her. She told me everything was fine. I realize now it wasn’t true, but I didn’t at the time.”

I smiled doubtfully. “It must upset you, though. I’d be mortified if my mother didn’t feel able to tell me she was in trouble. I can just about understand why she wouldn’t ask strangers for help…although she seems to have tried by going to the village. But her daughter? Wouldn’t she have been straight on the phone to you as soon as the water failed?”

“You should ask Jess that question. She was always the first person Mummy called in a crisis. Why didn’t she do anything?”

“Who was the second?”

Madeleine frowned. “I don’t understand.”

“Who did your mother phone when Jess wasn’t available? You?”

“I was too far away.”

“So Jess turfed out every single time. For how long? Twelve years? And before that her father? Was either of them ever paid?”

“It wasn’t a question of payment. They did it because they wanted to.”

“Why? Because they were so fond of Lily?”

“I’ve no idea what their reasons were. I always found it rather sad…as if they couldn’t get over the class barrier. Perhaps they felt they had to follow in Jess’s grandmother’s steps and play servant to the big house.”

I gave a snort of laughter. “Have you ever actually been to Barton Farm, Madeleine? The house is marginally smaller than this, but it’s in a lot better repair. At a rough guess, and with all the land she has, I’d say Jess’s estate is worth two or three times your mother’s. If she ever sold up, she’d be a millionairess. Why on earth would someone like that want to play servant to impoverished gentry?”

She smiled faintly. “You’re assuming she owns the property.”

“I’m not assuming anything. I know it for a fact. I believe you do, too.” I took a thoughtful puff of my cigarette. “But why does it matter to you so much that everyone should think she’s a tenant?” I went on curiously. “Does it stick in your throat that her family built on their successes while yours frittered theirs away?”

As a lure, it almost worked. “They wouldn’t have anything if it hadn’t been for-” She clamped her mouth shut suddenly.

I tapped more ash into the sink to ratchet up her irritation. “You’re lucky she’s so self-effacing. If Winterbourne Barton knew she was the richest woman in the valley, you wouldn’t get a look-in. They’d be queueing up to lick her arse.”

If looks could kill, I’d have had a dagger in my chest. “There wouldn’t be room,” she snarled. “They’d have to get you out of the way first. Everyone knows you’re her latest conquest.”

My eyes watered as I choked on some smoke. “Do you mean her latest fuck? I might have thought about it if she wasn’t shagging Peter every night. Wouldn’t you say that’s a fairly good indication that she prefers cocks to cunts?”

“You’re disgusting.”

“Why?” I murmured in surprise. “Because I said she shags blokes? Surely Nathaniel’s told you what a good a lay she is? I gather they went at it like rabbits before you muscled in on the act. He’s down here all the time, trying to resurrect the good old days. He was even here the night Jess found Lily.”

A flicker of something showed in her eyes. Fear? She looked away before I could decide. “That’s rubbish.”

“Then who turned the utilities back on before Lily’s solicitior and social services came in?”

It was like pressing the “on” button. As long as I fed her questions she’d prepared for, she could produce her rehearsed answers. “Jess, of course,” she said confidently. “She was the only one who knew Mummy had collapsed. Everything she did was designed to cover her tracks. She could have phoned for an ambulance or put Mummy back to bed herself and called a doctor…but instead she drove her to the farm and waited till the morning to bring in social services. Why did she do that if it wasn’t to give herself time to put things straight at Barton House?”

“It was too cold to wait for an ambulance, so Jess took Lily back to the farm and called the surgery as soon as she got there. A locum turned up an hour later-by which time your mother was cleaned, fed, warm and fast asleep-and he advised Jess to leave her where she was until the morning. I thought you knew all this.”

“Why at the farm, though? Why not here?”

“Because it would have meant carrying your mother fifty yards just to get her to the back door, and she couldn’t see anything because none of the outside lights were working,” I said patiently. “Instead, she drove the Land Rover onto the lawn and lifted Lily into it. Her first plan was to take Lily to hospital herself, but as soon as your mother was in the warmth of the cab, and wrapped in the dogs’ blanket, she perked up and asked for food.” I eyed Madeleine curiously. “Peter told me all this within a week of my arrival. Did he not tell you? I thought you were such friends.”

“Of course he did,” she snapped, “but he’s only repeating Jess’s story. He doesn’t know it for a fact because he wasn’t here.”

I shrugged. “Then what did the locum say in the messages he left on your answerphone? Or social services? Did they give different explanations?”

“I didn’t listen to them all. The only one that mattered was Mummy’s solicitor saying she’d been taken into care…and I responded to that as soon as I got back from holiday.”

“So you didn’t hear the message that Jess left at twelve-thirty to say your mother was at the farm? The locum was with her when she did it. She told you you had twelve hours to take charge before the surgery alerted social services.” I folded my arms and watched her closely. “She gave you every chance, Madeleine, but you didn’t take it.”

“How could I? I was away.”

“Nathaniel wasn’t.”

“That’s not true. Nathaniel wasn’t in the flat either. He took our son to visit his parents in Wales. It’s something he does every year. Ask my in-laws if you don’t believe me.”

“It’s quite easy to pick up messages from a distance…and most of Wales is no farther from Dorset than London is. At a guess, it was you who turned the utilities off and Nathaniel who raced down here to put them back on before social services came in the next morning.”

“That’s ridiculous,” she said, her breath hissing angrily through clenched teeth.

“No one else had a reason to make Lily’s life miserable.”

“Jess did.”

“I can’t see it,” I said. “I don’t think the police will either. She wouldn’t have written to you if it meant you’d find out she’d been mistreating your mother.”

“What reason did I have?”
