The Ghost Tree: Gripping historical fiction from the Sunday Times Bestseller. Barbara Erskine

don’t you tell him to go?’ Harriet was Ruth’s oldest friend. The two women had been at school together and had remained in touch over the years since. To Ruth, the only child of comparatively elderly parents, Harriet had been the nearest thing to a sibling. It was a given that she would have come up to Edinburgh for Ruth’s father’s funeral.

      ‘I can’t just throw him out. He was so kind to Dad.’

      The presence of Timothy Bradford in the house had been an unwelcome surprise when she arrived. He appeared to have been staying there for some time, very much at home.

      ‘Have you asked him what his plans are?’

      Ruth shook her head. ‘It’s too soon.’

      ‘No, it’s not.’ Harriet’s voice was crisp. ‘He’s obviously not going to go until you say something.’ She gave Ruth a quizzical glance. ‘I know you feel you should have come up here sooner when your dad fell ill, but be honest, Ruth, he didn’t tell you there was a problem; you came as soon as you knew. And if Timothy was comfortable looking after him, that was his choice. On his own admission, your dad has given him free bed and board in Edinburgh for months, but it’s over now. Whatever you decide to do with the house, he has to go.’

      ‘You’re right,’ Ruth agreed gloomily.

      ‘Do you want me to tell him?’

      ‘No!’ Ruth was shocked. ‘No, of course not.’ She took a deep breath. ‘I’ll do it tomorrow after you’ve gone.’ She frequently found herself resenting Harriet’s calm assumption that she was the more efficient of the two of them, but it wasn’t as if they saw each other often enough these days to make an issue of something so trivial.

      ‘So, what will you do after you’ve got rid of him?’ For all their closeness there had been long gaps when they hadn’t seen each other, especially since Harriet had moved away from London and down to the West Country. She surveyed her friend fondly. Ruth had large grey eyes, her most striking feature; as a child they had always been the first thing people mentioned about her. Her hair on the other hand was a light golden brown, something she had never bothered about and which had become streaked with silver at the temples at a remarkably early age. It had suited her then and suited her now. Harriet had always felt strangely protective of Ruth. She was one of those people who seemed too vulnerable to exist in the normal world; which was rubbish. At some level Ruth was tough as old boots.

      ‘I haven’t any plans yet. I’m not sorry I gave up teaching; I’d been there too long and I was growing stale. I was just learning to appreciate my freedom as mistress of my own destiny when I found out Dad was so ill and I thought I’d have to move up here permanently to look after him.’ Ruth sighed sadly. ‘No more freedom after all. That was why I rented out my London flat. I didn’t realise how short a time he had left.’

      ‘And what of the husband?’ Harriet never stooped to giving Richard his name.

      Ruth laughed quietly. ‘The ex-husband is fine. You saw him at the funeral. We agreed to go our own ways. We still talk occasionally. We’re friends.’

      There was a painful pause, a silence that covered so much that had happened: her longing for a child and the bleak discovery that Rick was unlikely ever to father a baby, the failed IVF, the decision to give up trying, the sense of empty pointlessness that followed.

      Harriet cleared her throat uncomfortably. ‘So, you really are fancy-free?’

      ‘I suppose so.’

      ‘With no London flat, at least for now, but instead an Edinburgh house.’

      ‘Yup.’

      ‘Any gorgeous men on the horizon?’

      ‘No.’

      ‘Not Timothy?’

      ‘Definitely not Timothy.’

      ‘So, what did you do with yourself those last few months before you came up here? If you weren’t working, you must have been doing something.’

      ‘Living off my share of the sale of Rick’s and my house. I bought the flat with my half and that left me some change to give me the chance to stop and think about what I really want to do with the rest of my life. Meanwhile, I was free to read the books I want to read instead of set texts; explore the world, relax; take up hobbies for the first time since I grew up!’

      ‘Stamp collecting?’ Harriet’s voice was dry, though there was a twinkle in her eye.

      Ruth laughed. ‘If you must know, I’ve started researching my family tree. My mother’s family tree, to be exact.’

      ‘Bloody hell, Ruth! I thought your father’s attitude to your ancestors would have put you off that for life.’

      Ruth grimaced. ‘On the contrary. I always planned to do it one day, if only to show him I didn’t care how much he hated them. Besides, I want to find a family, any family. Dad was my last living relative.’ There was a long pause. ‘So,’ she changed the subject abruptly, ‘enough of that. Let’s talk about you. You haven’t told me what you’ve been up to.’

      ‘I’m still writing.’ Harriet leaned forward, as always intense, her short red hair framing a face focused with sudden excitement. She hesitated momentarily then went on. ‘I’m just starting a book about the vital role of women in the Second World War. Code-breakers, SOE – the specially-trained people who went overseas as spies and saboteurs – pilots, that sort of thing, telling the story of one particular woman from each category. I’ve arranged to go and stay with some friends in North Berwick while I’m up here. Liz and Pete Fleming. Liz discovered that her grandmother worked for SOE. She was dropped behind enemy lines and worked undercover near Paris. Can you imagine how brave you had to be to do that? So I’m writing a chapter about her.’ Her eyes were sparkling. ‘Another of my subjects is a woman called Dion Fortune who lived in Glastonbury.’ Harriet lived in a cottage in the famously eccentric Somerset town. It was there she had already written several well-received popular biographies. ‘Dion was a famous occultist. She lived at the foot of the Tor and conducted séances and meditations there. During the war, and this is the fascinating bit, she organised her followers to fight Hitler with magical energies and imagined armies of Arthurian knights with swords. You did know Hitler was into the occult?’

      ‘I think I’d heard, yes.’ Ruth was looking bemused.

      ‘Comparatively few people have heard of Dion these days, but that’s the point. These are unsung heroines and she’s probably the oddest of them all.’

      ‘Magic was my mother’s thing,’ Ruth put in wistfully. ‘She’d have loved Glastonbury. She used to go to crystal shops and buy incense and pretty stones. She kept them in a bag to calm her nerves; she used to meditate. Dad hated her interest in all that stuff. I can still remember the row they had when he caught her looking at them. She tried to stand up for herself, but he sulked like a spoilt child if she tried to defy him and as far as I know she gave it all up.’ Her face clouded as she remembered. ‘To him, meditation and prayer were pointless at best and childish superstition at worst.’

      Intellectually she understood why her father had hated religion, or, his second relentless dislike, anything or anyone whom he regarded as posh, but what she had never been able to forgive was the way he had taken his resentments on both counts out on his own wife.

      Presumably it was an instinctive sense of self-defence as she was growing up that preserved Ruth from any interest in history or religion; she left home as soon as she finished school, first to study English literature at Cambridge University, then to learn to teach, then to take up a series of posts teaching English. She had even married an English teacher.

      She and Rick supported each other through the heartbreaks and trials that beset the marriage, but something in their relationship died with their hopes of a family. They began to drift apart and it was just after their tenth wedding anniversary that Ruth had rebelled and ended both marriage and career.
