Susan realized that Gary was drunk. As he’d been talking he’d finished one can of lager and most of a second, and he had obviously drunk a few before she arrived.

‘Did you know anything at all about Caroline’s life?’ she asked.

His bright eyes narrowed. ‘I knew she was a fucking dyke, if that’s what you mean.’

‘How did you know that?’

‘She told me. One of her visits.’

‘But your father doesn’t know?’

‘No. It wouldn’t make a scrap of difference if he did, though. It wouldn’t change his opinion. As far as he’s concerned the sun shone out of her arse and that’s all there is to it.’ He tossed the empty can aside and picked up another from the low, cigarette-scarred table.

‘How do you feel about her death?’

Gary was silent for a moment, then he looked directly at Susan. ‘I can’t say I feel much at all. If you’d asked me a few years ago, I’d have said I felt glad. But now, nothing at all. I don’t really care. She made my life a misery, then she left and lumbered me with the old man. I never had a chance to get out like her. And before that, she made everyone’s life miserable at home. Especially mum’s. Drove her to an early grave.’

‘Did you talk to her much when she visited?’

‘Not by choice,’ he said, reaching for another cigarette. But sometimes she wanted to talk to me, explain things, like she was taking me into her confidence. As if I cared. It was funny, almost like she was apologizing for everything without ever quite getting round to it. Do you know what I mean? “I want you to know, Gary,” she says, “how much I appreciate what you’re doing for Dad. The sacrifices you’re making. I’d help if I could, you know I would…” and all that fucking rubbish.’ He imitated her voice again: ‘ “I want you to know, Gary, that I’m living with a woman in Eastvale and I’m happy for the first time in my life. I’ve really found myself at last. I know we’ve had problems in the past…” Always that “I want you to know, Gary…” as if I fucking cared what she did, the slut. So she’s dead. I can’t say I care one way or another.’

Susan didn’t know whether to believe him. There was more pent-up passion and rage in his tone than she could handle, and she wasn’t sure where it was coming from. All she knew was that she had to get out of this oppressive house, with its vast cold and crumbling spaces. She was beginning to feel dizzy and nauseated listening to Gary Hartley’s high-pitched vitriol, which, she suspected, had as much to do with self-pity at his own weakness as anything else. Quickly, she muttered her farewell and headed for the door. As she walked down the hallway she heard an empty lager can crash against the wainscotting, followed by the screech of the top being ripped off another.

Outside, she breathed in the cold damp air and leaned against the roof of her car. Her gaze fixed on the melting snow that dripped from the branches of a tall tree. Her hands were shaking, but not from the cold.

Before she had driven far, she realized that she needed a drink. She pulled into the car park of the first decent-looking pub she saw outside town. There, in a comfortable bar lit and warmed by a real coal fire, she sipped a small brandy and thought about the Hartleys. She felt that her visit had barely scraped the surface. There was so much bitterness, anger and pain festering underneath, so many conflicting passions, that it would take years of psychoanalysis to sort them out.

One thing was clear, though: whatever the reasons for the family’s strife, and whatever Caroline’s reasons for running away, Gary Hartley certainly had a very good motive for murder. His sister had ruined his life; he even seemed to blame her for his mother’s death. Had he been a different kind of person, he would have handled the burden some other way, but because he was weak and felt put upon, blood had turned to vinegar in his veins. As Susan had just seen, it didn’t take more than a few drinks to bring the acid to the surface.

It would be very interesting to know what Gary Hartley had been doing between seven and eight o’clock the previous evening. As he had told her, the old man slept most of the time, so it would have been easy for Gary to nip out for a while without being missed. She hadn’t asked him for an alibi, and that was an oversight. But, she thought, taking another sip of brandy and warming her hands by the fire, before we start to get all paranoid again, Susan, let’s just say this was only a preliminary interview It would be a good idea to approach Gary Hartley again with someone else along. Someone like Banks.

As she tilted her head back and finished the rest of her drink, she noticed the bright Christmas decorations hung across the ceiling and the string of cards on the wall above the stone fireplace. That was another thing she remembered about the Hartley house. In addition to the cold and the overwhelming sense of decay, there had been nothing at all in the entire huge place to mark the season: not a Christmas tree, not a card, not a sprig of holly, not a cutout Father Christmas. In that, she realized bitterly, the place resembled her own flat all too closely. She shivered and walked out to the car.

Banks drove carefully down the hill into Redburn as his tape of Bartok’s third string quartet neared its end. The gradient wasn’t quite as steep as at Staithes, where you had to leave your car at the top and walk, but it was bad enough. Luckily, the snow had petered out somewhere over the heathered reaches of the North York Moors and spared the coast.

The narrow hill meandered alongside the beck down to the sea, and it wasn’t until he turned the final corner that Banks saw the water, a heaving mass of grey sloshing against the sea wall and showering the narrow promenade with silver spray. Redburn was a small place: just the one main street leading down to the sea, with a few ginnels and snickets twisting off it where cottages were hidden away, half dug into the hillside itself, all sheltered in the crescent of the bay. In summer the jumble of pastel colours would make a picturesque scene, but in this weather they seemed out of place, as if a piece of the Riviera had been dug up and transported to a harsher climate.

Banks turned left at the front, drove to the end of the road and parked outside the Lobster Inn. Where the road ended, a narrow path led up the hillside, providing the only access to the two or three isolated cottages that faced the sea about halfway up: ideal places for artists.

The cold whipped the breath out of him and the air seemed full of sharp needles of moisture, but Banks finally reached his goal, the white cottage with the red pantile roof. Like the rest of the village, it would look pretty in summer with its garden full of flowers, he thought, but in the dull grey air, with the wind curling smoke from the red chimney, it took on a desolate aspect. Banks knocked at the door. Somewhere the wind was whistling and banging a loose shutter. He thought of Jim Hatchley and wondered how much he was enjoying the seaside not many miles away.

The woman who answered his knock had the kind of puzzled expression on her face that he’d expected. There couldn’t be many people dropping in on such a day in such an isolated place.

She raised her dark eyebrows. ‘Yes?’

Banks introduced himself and showed his card. She stood aside to let him in. The room was a haven from the elements. A wood fire crackled in the hearth and the smell of fresh-baked bread filled the air. The wooden furniture looked primitive and well-used, but homely. The woman herself was in her mid-twenties, and the long skirt and blouse she wore outlined her slender figure. She had a strong jaw and full, red lips. Beneath her fringe of dark hair, two large brown eyes watched him go over and rub his hands in front of the fire.

Banks grinned at her. ‘No gloves. Silly of me.’
