‘I was a crisis response consultant,’ Ben said. ‘I worked freelance to help locate kidnap victims. Especially children. But not any more. As I told you at interview, I’m retired.’

‘Especially children,’ Bradbury echoed sadly.

‘This has something to do with Zoë,’ Ben said.

Jane Bradbury got back up from her seat. She walked through the french windows into the house and came back a few moments later holding a framed photo. She set the silver frame down on the table and nudged it towards Ben. ‘Do you remember her? She was just a child, the last time we saw you.’

Ben cast his mind back to those days. It all seemed so distant. So much had happened since. He remembered a sparkling little thing running across the lawn with the dog trotting happily after her, sunlight in her hair and a world of joy in her gap-toothed little smile.

‘She was about five, six years old then?’

‘Almost seven,’ Bradbury said.

‘So she’s twenty-five, twenty-six now.’ Ben reached out for the photo. The silver frame was cool to the touch. He turned it towards him. The young woman in the picture was strikingly pretty, long blond hair and a full smile. It was an honest, happy picture of her hugging her little dog.

Bradbury nodded. ‘She turned twenty-six in March.’

Ben put the picture down. ‘What’s wrong? Zoë’s in some kind of trouble? Where is she?’

‘That’s the problem. She was supposed to be here. And she’s not.’

‘I’ve had too much wine already,’ Jane Bradbury said suddenly. ‘I’ll go and make us some coffee.’

Ben watched her go. There was a lot of stiffness in her movements, like someone under enormous pressure. He frowned. ‘What’s the problem?’

Bradbury toyed uncomfortably with his pipe. He glanced over his shoulder. Whatever he was about to say, he obviously preferred to say it without his wife there. ‘We’ve always loved her deeply, you know.’

‘I’m sure you have,’ Ben said, not sure where this was going.

‘This is a little hard for me to talk about. Personal things.’

‘We’re friends,’ Ben said, meeting his eyes.

Bradbury smiled weakly. ‘When Jane and I got married, it took us a long time before we could have a child. It was nobody’s fault.’ He made a face. ‘It was my fault. Embarrassing. The details are -’

‘Never mind the details. Go on.’

‘After five years of trying, Jane became pregnant. It was a boy.’

Ben frowned. The Bradburys had no son.

‘You can guess what happened,’ Bradbury continued. ‘His name was Tristan. He didn’t see his first birthday. Cot death. One of those things, we were told. It was devastating.’

‘I’m sorry,’ Ben said, and meant it. ‘That must have been tough.’

‘A long time ago now,’ Bradbury said. ‘But it’s still very raw. So we tried to have another, but again it was hard for us. We were on the point of giving up, and talking about adoption, when Jane conceived. It seemed like a miracle to us. Nine months later we had the perfect little girl.’

‘I remember her well,’ Ben said. ‘She was lovely. And bright.’

‘She still is,’ Bradbury replied. ‘But for so many years we were terrified of losing her. Irrational, of course. Her health’s always been excellent. But these things leave a mark on you. I admit we spoiled her. And I’m afraid we perhaps didn’t bring her up quite the way we should have.’

‘What is she doing now?’

‘She went on to become a brilliant academic. She’s never really had to try. She sailed through her studies. Archaeology. First class from Magdalen. She was all set for a glittering career. Biblical archaeology is a major field of study. It’s a relatively new science, and Zoë has been one of its pioneers. She was part of the team that found those ostraka in Tunisia last year.’

Ben nodded. Ostrakon, from the Greek, meaning shell. In its plural form, it was the name archaeologists gave to fragments of earthenware that once served as cheap writing materials. Ostraka had been widely used in ancient times for recording contracts, accounts, sales registers, as well as manuscripts and religious scripture.

‘I read about that find,’ he said. ‘I had no idea I knew the person responsible for it.’

‘That was such a wonderful moment for her,’ Bradbury replied. ‘In fact, what her team discovered was the biggest haul of intact ostraka found since the 1910 excavation in Israel. They were buried deep under the ruins of an ancient temple. An amazing find.’

‘She’s clever,’ Ben said.

‘She’s exceptional. But that’s not all she’s done. She’s written papers and co-authored a book on the life of the Greek sage Papias. She’s even been on television a few times, interviewed on an archaeology channel.’

‘You sound very proud of her.’

The professor smiled. Then the shadow fell back over his face. His chin sank down to his chest. He fingered the pipe. It had gone out. ‘Professionally, academically, she’s wonderful. But her private life, and our personal relationship with her, is a disaster.’ Bradbury raised his hands and let them flop down on his thighs. A gesture of helplessness. ‘What can I say? She’s wild. Has been since the age of fifteen. We just couldn’t control her. She was in trouble with the law a few times for petty crimes. Shoplifting, picking pockets. We used to find stolen items in her room. It was all a joke to her. We hoped she would grow out of her wildness in time, but she didn’t. Drinking. Parties. All kinds of reckless behaviour. It’s been fighting and difficulty all the way. She’s argumentative, aggressive, terribly headstrong, always has to have it her way. It takes very little to provoke her into a quarrel.’ He looked up at Ben with red-rimmed eyes. ‘And I know it’s our fault. We spoiled her completely, because we felt so lucky to have been given a second chance at having a child.’

Ben had been sipping his wine steadily as Bradbury talked. He filled his glass again. ‘Let’s talk straight, Tom. You told me you were concerned that she wasn’t here. Has she gone missing?’

Bradbury nodded. ‘Nearly a week now.’

‘And you think she’s in some kind of trouble?’

‘We don’t know what to think.’

‘A week isn’t a long time, under the circumstances. You said yourself, she’s wild. She’ll turn up.’

‘I wish I could believe that.’

‘You’re telling me all this because of what I used to do.’

‘Yes.’

‘So you’ll listen to my professional opinion.’

Bradbury shrugged. ‘Yes.’

‘People do go AWOL from time to time,’ Ben said. ‘Now, if someone does go missing and there’s clear evidence that something has happened to them, there are things we can do to get them back. But you need to distinguish between a legitimate missing persons case and someone who’s just a little wayward, argues with her parents, likes to have fun and has gone off the radar for a short while.’

‘She’s done it before – gone off the radar as you say,’ Bradbury said. ‘We’re realistic. We can accept a lot of things. We accept that she’s free and likes to enjoy herself. Sexually, I mean.’ He flushed with embarrassment. ‘But this time it’s different. This time it’s really strange, and we have the most terrible feeling about it.’

‘So what makes this time different?’

‘The money. I mean, where did all that money come from?’

‘What money?’

‘I’m sorry. Let me backtrack. Zoë was working on an excavation project in Turkey. It was meant to last until the end of August. But then the next thing we knew, she left it early and was on Corfu. We have some friends there. She was staying with them for a while.’ Bradbury paused. ‘Then, suddenly, she seemed to have all this money. She’s a doctoral student. She doesn’t have money, at least no more than she needs. According to our friends she was suddenly loaded with it. Thousands. And the way she was spending it, it was as though it would never run out. Started partying all the time, coming home drunk with a different man every night.’
