‘Why don’t you take a knife and kill me, Thomas? It would be quicker and more honest!’

      Susan Craig was shouting now, her voice harsh with despair. ‘Dear God, you drive me to do this! You and your sanctimonious cruelty.’ She was standing near the window, tears pouring down her face.

      Adam, thin, skinny, and tall for his age, which was fourteen, was standing outside his father’s study window, his arms wrapped tightly around his body, his mouth working with misery as he tried to stop himself shouting out loud in his mother’s defence. The quarrel, growing steadily louder and louder, had been going on for what seemed like hours, and for what seemed like hours he had been standing there, listening. What had she done – what could she have done? – to make his father so angry? He didn’t understand.

      ‘Now you take the name of the Lord in vain as well! Is there no end to your wickedness, you stupid, senseless woman?’ Thomas’s voice too was almost incoherent.

      ‘I’m not wicked, Thomas. I’m human! Is that so evil? Why can’t you listen to me? You don’t care! You never have, damn you!’ His mother’s voice was shrill, out of control, his father’s a deep rumbling torrent of words designed to override and to annihilate.

      The boy’s eyes were blind with tears as he put his hands over his ears, trying to block out the sounds, but it was no use; they filled the echoing rooms of the huge old stone-built manse and spilled out of the windows and doors until they seemed to fill the garden and the surrounding village of Pittenross, the woods and even the sky.

      Suddenly he couldn’t bear it any more. Stumbling in his haste, unable to see where he was going for his tears, he turned and ran for the gate.

      The manse stood at the end of a quiet village street, hidden behind the high wall which all but encompassed house and garden, save where, at the far end of the vegetable patch, the broad sweep of the River Tay rattled over shingle and rock. To the left of the house stood the old kirk amongst its attendant trees, its lawns and gravel paths deserted behind high ornate railings and an imposing gate. To the right the street, lined by grey stone-built houses, was silent and at this hour empty of people.

      Adam ran along the street, cutting down through Fishers’ Wynd, a small alley between high, blank walls, skirted some rough ground, half-heartedly gardened by the wife of one of his father’s elders, hopped across the river by way of shining black rocks and stones and, climbing a wire fence, began to run up through the thick woods which clung to the lower slopes of the hill. He ran until he could run no longer, sure that if he stopped he would still be able to hear the sounds of his parents quarrelling.

      The quarrels had been growing worse over the past few weeks. He had no brothers or sisters to share his burden, no other family in whom he could confide, no one in the village he felt he could talk to. His loyalty to his parents was absolute and somehow he knew that this was private, not something that anyone else should know about, ever. But he didn’t know what to do, and he could not cope with what was happening. His beautiful, young happy mother, happy at least when he and she were alone together, whom he adored, had changed into a pale, short-tempered shadow of herself, whilst his father, always a large man, burly and of florid complexion, had grown larger and more florid. Sometimes Adam looked at his father’s hands; huge, powerful hands, the hands of a labourer rather than the hands of a man of God, and he shuddered. He knew how hard they could wield the strap. His father believed in beating his son for the good of his soul at the slightest transgression. Adam did not mind so much for himself, he was used to it. Almost. But he was terrified, blindly, completely and overwhelmingly terrified that his father might beat his mother.

      He never knew why they quarrelled. Sometimes at night, lying in his dark bedroom, he could hear the occasional word through the wall, but they made no sense. His mother adored the mountains and the river and the village and the life of a minister’s wife, and she had dozens – hundreds, or so it seemed to her son – of friends, so why should she cry out that she was lonely? Why should she say that she was so unhappy?

      Without thinking about where he was going, he had taken a favourite path up through the trees, following a tumbling, rocky burn up the hillside, seeing flashes of white foaming water from rock pools and waterfalls as he climbed on between birch and rowan and holly, through larch and spruce, to where the woods thinned and the mountainside took over.

      His pace had slowed now and he was badly out of breath, but still he ploughed on, following a sheep’s track through the grass and prickly heather, skirting the rocky outcrops flung up millennia ago by volcanic and glacial fury. He was heading for the carved stone cross-slab, erected, so tradition had it, by the Picts, the people who had inhabited these hills even before the Scots came, to stand sentinel on the hill far above the village and the river. He always went there when he was miserable. It stood near a small wood of old Scots pine, part of the ancient Caledonian Forest which had girdled the mountains centuries before, and it was his own very special, private, place.

      It had stood there on the flat top of the ridge, half circled by the old trees, for more than fourteen hundred years, rearing, at a slight angle to the vertical, over a view which on a clear day extended perhaps thirty miles to the south, to the north only two or three before the high mountains blocked the sky. On the face which turned towards the sun there was a huge cross, set within a wheel in the manner of the Celts, carved with intricate lacy patterns, the everlasting design which represented eternal life. On the back were stranger, heathenish carvings – a snake, a jagged broken stave, a mirror and a crescent moon – and of these symbols the village as a whole and his father in particular disapproved violently. Thomas Craig had told Adam that the symbol stones had been carved by worshippers of the devil, who had left them there on the high lonely hillside with their hidden message to all who came after them. Sometimes Adam used to think it was a miracle that the stone had not been torn down and broken and utterly destroyed – perhaps it was because it was too far from the village, too much effort to do it, or perhaps it was
