As his car bumped over the mountain track towards the white painted stone cottage, Hugh gave a wry grin. Where else would his old friend, Meryn Jones, have come to rest in his peripatetic life when he needed to be near the National Library of Scotland for his research, than this remote glen in the Pentland hills? Any nearer the city would have been an anathema.

      The two men had first met at Jesus College, Oxford over thirty years before, their point of contact their intense interest in the Celtic world in which both were working on post-graduate research, prior to setting off in very different directions, Hugh to Trinity College, Dublin, Meryn to his native Wales where he was to centre his life around his study of Druidism.

      Parking near the door Hugh climbed out and looked round appreciatively. The cottage, nestling beneath a glorious great mountain, and within earshot of a swiftly running rocky burn was surrounded by a small garden where vegetables and herbs – always herbs, wherever Meryn lived, herbs for healing, and for magic and for divination – vied with flowers for the space within the tumbled grey stone garden walls.

      As the two men shook hands and then turned to walk inside, Hugh grinned. He could smell coffee. Most of his friend’s eccentricities he could tolerate, but herb tea morning noon and night was not one of them.

      Tall, with dark hair greying at the temples, Meryn was in his mid-fifties, though his confident stride and upright posture had not changed at all from that of the young man who had gone from Oxford to live and work and study in the mountains of mid-Wales.

      He led Hugh into the cottage where a large work table stood in the centre of the book-lined living room; its stone walls were nearly completely hidden by the shelves, the deep window recesses bright with scarlet geraniums, the fire in the hearth lit even though it was June.

      He gestured Hugh towards one of the two deep armchairs and fetched their drinks.

      ‘You look troubled, my friend,’ Meryn said as he set down a cup beside Hugh.

      Hugh sighed. There were never any preambles with Meryn. Straight to the point.

      ‘I’m tired. Getting old and grouchy.’

      Meryn smiled. ‘You’ve always been grouchy, Hugh. As for old, you’re younger than me. Prime of life! The target of many a beautiful undergraduate’s lustful fantasies if rumours are true.’ He smiled as he glanced across at the other man, as always acute in his summing up of the situation. ‘Time for a sabbatical, perhaps?’

      ‘In two years’ time.’ Hugh reached for his coffee and sniffed it appreciatively before taking a gulp. His host had a cup of something green steaming away beside him. He had not touched it, Hugh noticed. ‘I dreamed about Alison,’ he went on abruptly. ‘I thought I was moving on, like we’re told to, you know, getting on with my life,’ he shrugged, ‘and it’s getting easier. Then suddenly, this.’

      Meryn was studying his face. His silence led Hugh to continue.

      ‘She told me to come and see you.’ He gave an embarrassed laugh.

      ‘She is a wise lady.’

      Hugh nodded. Is. Not was. That was typical of Meryn. He and Meryn had re-established their close friendship thanks to Alison. She had adored Meryn’s books, written to him without realising that he and her husband had once been so close, met him at last the year before she died, then on discovering the length and depth of their former friendship, insisted that Hugh and he get in touch again. They had kept in contact over the years, but their approach to their studies was very different and had in a sense driven them apart, Hugh’s academic and based in the empirical record, Meryn’s spiritual and psychological. His approach to Druidry was rooted not only in study, but in memory and meditation – in experience – something Hugh found hard to understand.

      Meryn didn’t deny being a Druid nowadays. In fact it was what he called himself. Not a member of any organisation. Nothing formal. Just a deep, passionate philosophy. A way of living. A way of believing and of remembering which came from the distant Celtic past of his country and his ancestors and his finely tuned intuition which was undoubtedly psychic. He frowned as he sat studying his visitor. His intuition was telling him now that something was very wrong.

      Hugh put down his cup. He respected Meryn’s learning, and his natural wisdom if not his academic purity, and lately he had begun to regard his friend as something of a mentor and guru. Meryn seemed to possess a knowledge and assurance which he himself lacked. It was something he envied.

      Meryn reached for his drink at last. ‘You must let her go, Hugh.’

      ‘Who?’ Hugh started almost guiltily.

      ‘Alison, of course.’ Meryn was watching him closely. ‘Who did you think I meant?’

      Hugh shook his head. He leaned back in the chair and took a deep breath. Then he plunged into his story, coming straight to the point. ‘Did you ever meet Dr Lloyd Rees when you came up to the DPCHC?’

      Meryn shook his head. ‘One of your adoring disciples?’

      Hugh gave a bitter smile. ‘I used to think so.’

      After a pause Meryn asked, ‘So, what has Dr Lloyd Rees done to displease you?’

      ‘She’s written a damn stupid book. Made a complete ass of herself. It’s going to show up the whole department, and she’s –’ He paused abruptly. ‘She’s done something else unutterably stupid as well, and I don’t know what to do about it.’

      ‘What sort of thing?’

      ‘She’s stolen something, Meryn. Something of inestimable value.’ Hugh glanced up.

      He hadn’t actually seen her do it, but when he had gone back to the office and searched the chaos of his desk it had gone. It had to have been her. Who else would have done it?

      ‘Have you asked her?’

      Hugh shook his head.

      ‘Why?’

      ‘I didn’t want to confront her, I suppose.’ Hugh shrugged. Scowling, he levered himself out of his chair and paced restlessly up and down the floor a couple of times.

      Thoughtfully Meryn watched him. Hugh was growing more agitated by the second.

      ‘She doesn’t realise what she has started!’ Hugh burst out suddenly. He flung himself down on the chair again and drummed his fingers on his knee, staring into the fire.

      ‘And what has she started?’ Meryn’s question was very soft as he studied the other man’s expression.

      ‘A war.’ Hugh said the words almost absent-mindedly. ‘She started a war. Stupid bitch!’ His voice had changed. Deepened. Become raw with anger. ‘She will pay for what she has done!’

      Meryn raised an eyebrow. ‘Strong words.’ He was carefully scanning Hugh’s face.

      ‘Not strong enough!’

      ‘Are we still talking about Dr Lloyd Rees?’

      ‘No! I’m talking about Cartimandua!’ Hugh’s eyes were closed now, his mouth set in a grim line.
