'Here you are now, Helen,' she said as Helen approached from the car.

She had never in her life kissed her grandmother, or shaken her hand; now as she came close to her she did not know what to do.

'Granny, I'm sorry for barging in on you like this.' 'Oh, it's a great surprise, Helen, it's a lovely surprise.' Her grandmother searched her face and then looked back towards the gate to check that no one else was coming. She turned and walked into the house. The big old Aga cooker in the kitchen was on full, and the room was warm. As Helen came in, the two cats jumped up to the top of the dresser – their constant presence there looking down on the room had amazed Cathal and Manus the previous year – and sat there watching her suspiciously.

'Now, Helen, there's tea on and I could make you up a fry.'

'No, Granny, I'll just have tea. I had a meal on the way down.'

She realised that her grandmother was biding her time, asking nothing, waiting to be told.

'Granny, I have very bad news.'

Her grandmother turned and put her two hands into the pockets of her apron as though searching for something. 'I know, Helen. I knew that as soon as I saw you.'

She remained standing as Helen told her the story. She concentrated fiercely on what was being said so that Helen felt, when she was finished, that the old woman could have repeated every single word she had said. There was something which she had forgotten: in the corner of the kitchen sat a huge television; her grandmother had access to all the English channels as well as the Irish ones. She watched documentaries and late-night films and prided herself on being well informed on modern subjects. She knew about AIDS and the search for a cure and the long illnesses. 'There's nothing can be done, Helen, so,' she said. 'Nothing can be done. It was the same years ago with your father's cancer. There was nothing the doctors could do. And poor Declan's only just starting his life.'

'What will I do about my mother?' Helen asked.

'You'll go into Wexford in the morning and you'll break the news to her softly, Helen. Let her sleep tonight now. It's the last night's sleep she'll have for a long time.'

Her grandmother made tea and put biscuits on a plate. She sat down opposite Helen. It was still bright outside, and Helen felt a desperate need to go down to the strand, to get away from the intensity of her grandmother's attention.

'I'll make you up a bed now,' her grandmother said. 'The room hasn't been used since you were here last summer. Your mother never stays, and she hasn't been here much recently.'

'Have you fallen out with her?' Helen asked.

'Ah, not really. She still thinks she's going to get me to move into Wexford. What if I broke my leg out here, she asked me. And I told her I've plenty of money now that I sold the sites; that old field that was full of ragwort. I never consulted her or asked for her opinion. And that's all is wrong with her, but she's well over it now. She's good at forgetting things, putting them behind her. And I had the central heating installed without as much as a by-your-leave from her. Come on until I show you.'

She stood up and Helen accompanied her into the old dining-room. She pointed at the new white radiator, and then opened the doors of the two bedrooms off the dining-room with iron beds and bare mattresses. These two rooms also had radiators.

'I had it put in all over the house, and a big oil tank out the back. I bought a deep-freeze as well, so I have no worries. Your mother came down when the work was half done and said that the house would rot. She said that she had everything set up for me in Wexford. "It's a wonder, Lily," I said to her, "that you don't look high-up or low-down at me and I only ten miles out the road and you with your big car. Isn't it funny now that you've started to call when you know I have money?" Oh, she was raging. That was Easter and I didn't see her again until the end of May. She brought me down this.' She took a mobile phone from her apron pocket. She held it in her left hand as though it were a small animal. 'Oh, I told her I couldn't have a phone in the house. I'd worry about it, so I keep this here, it's turned off, I never use it.'

'But, Granny, you didn't mean it about the money.'

'No, Helen, but it was the only thing I could say that would make her stop trying to move me into the town. Oh, she was raging. And she'd be even more raging if she thought I told you. God help her, she'll have other things to think about now.'

Her grandmother went over to the window and peered out through the curtains.

'Is it easy to get down to the strand this year, Granny?' Helen asked.

'Oh yes, Helen, they dug steps and the steps have stayed, except for the last bit which is all marly and mucky.'

'I'd like to go down, just for a minute, just so I can think, it's been the longest day I've ever spent.'

'You go down, Helen, and I'll make up your bed, and I'd be glad if you'd drive the car into the yard or I'll have dreams about it rolling over the cliff.'

'I won't be long.'

The last strong rays of the sun could be seen over the hill behind the house. The air was still, with hardly a hint of the night about to fall. She felt almost healed and enclosed by her grandmother, but she knew, too, that her grandmother's attempt to suggest that nothing could hurt her was half pretence; the other half was a hardness built up over a lifetime of expecting the worst and then watching it unfold.

As Helen walked down the lane, she could see only the soft blue horizon and she could not imagine what the sea would look like in this light. And when she came to the edge she saw it down below: blue with eddies of dark blue and green in the distance. The sea "was calm and the waves rolled over with an easy, whispering crash. There was no barrier at the end of the lane; a car could easily be driven over and would tumble down the clay and marl on to the sand below. But no strangers were expected here; even in the summer it was not a place for casual visitors.

She found the steps and began to make her way down to the strand. The first stretch was easy, but soon she had to move carefully, holding on to weeds and tufts of grass, trying and failing to avoid the muck and the wet marl. She had to run down the last bit; it had always been like that, there was always too much loose sand at the bottom.

She stood on the narrow strand and shivered. Down here in the shadow of the cliff it seemed darker, colder, more like late August than late June. A line of sea birds flew a hand's distance above the calm water. And as each wave came in, it looked as though it might not break, but merely casually spill in and then get sucked back, but every time there came the inevitable lift and curl and a sound that was almost remote, a sound that, she believed, had nothing to do with her and had no connection to anything she knew, the quiet crashing of a wave.

From here as far as Keatings' the erosion had stopped or slowed down. No one knew why. Years earlier, it had seemed just a matter of time before her grandmother's house would fall into the sea, just as Mike Redmond's and Keatings' outhouse had done. And now Keatings' old white house itself was falling, but there was still one house between her grandmother's and the sea.

The erosion had stopped, but when she watched now she noticed fine grains of sand pouring down each layer of cliff, as though an invisible wind were blowing or there was a slow, measured loosening of the earth. It was bright enough still while she looked south to see Raven's Point and Rosslare Harbour. The strand, as she walked along, became narrower and stonier; she listened to the waves hitting the loose stones, unsettling them, knocking them against each other and then withdrawing. She saw, as she walked towards Keatings', that some of the red galvanised iron from a shed at the side had fallen now, and raw walls with strips of the old wallpaper were open to the wind, and soon they would fall too, until only a few people would remember that there had once been a hill and a white house below it way back from the cliff.
