‘I need to get right to the end of the tunnel.’ Perez had forgotten any question of risk assessment. ‘I need to know how big the entrance is on the seaward side.’

They walked in single file with Roger in the front, Perez in the middle and Sophie at the rear. The way into the tunnel from the Pit was wide enough for them to stretch out their arms, but it narrowed as they approached the shore. A slit of natural light appeared ahead of them, and there was a gust of salt fresh air from the sea. Now they were clambering over solid rock. Before they could reach the gap the tunnel had become so tight that they couldn’t move further forward. Sunshine shone through the strange vertical crack, picked out the colour in the rock at their feet in a sparkling strip.

‘A body couldn’t have been washed in there,’ Perez said. ‘Even with the force of the tide behind it. There’s no room.’ Sandy needn’t have worried about leaving Booth’s holdall down here. There was no way it would have been washed through the tiny gap.

‘Couldn’t the body have broken up at sea? A bone the size we found could just about have been sucked in.’

Still Perez’s thoughts were racing. ‘That’s possible. But if we find any more than that, it would be more than chance. Think of all the places along the coast where they could be washed up. And if we discover part of a corpse which is bigger than the piece we found, it couldn’t have come in this way.’ He looked at them. ‘Could it? The gap’s too narrow. If we come across more bones, or a bigger fragment of bone, it means the body was tipped down from the top of the Pit. Like Roddy Sinclair. It means another, older murder.’

Chapter Thirty-five

On Monday afternoon Fran went to visit Bella. She’d been thinking all weekend that she should go. She wasn’t sure what she could do to help, but the death of someone so young and beautiful needed marking. It demanded a certain ritual. She knew Bella would see things that way too. Fran thought she would be waiting in the Manse, queenly, expecting visits. That didn’t mean Bella would be feeling the loss any less – Roddy was as much a child to her as Cassie was to Fran – but she would want his going dramatized, turned into art, made splendid.

There was a small group of reporters at the entrance to the Manse. None of them looked local. They seemed content to sit in the sun and take photos of the Manse with their long lenses. A uniformed policeman stood there too, and he seemed to be enjoying the banter with the journalists. He let Fran through with a wave when she said she was there to see Bella. She thought she’d seen him before at one of Duncan’s parties. Those days seemed a long time ago.

Bella opened the door to her and as Fran had expected she was dressed to meet guests. Her clothes always tended towards the theatrical. Today she was wearing a long skirt, gathered and full, in a plum-coloured muslin, and a white embroidered cotton top. The effect was exotic – flamenco or gypsy. Fran despised herself for considering such trivial matters as dress, but Bella would want it to be noticed. Fran wondered if it would be tasteless to say how nice the artist looked and decided that it would be. Besides, she would know she looked good.

‘I wanted to come,’ she said. ‘I probably can’t do anything, and if you’d rather be alone, do say.’

‘No.’ Bella stood back, so she was framed by the light through the old kirk-style window. ‘Company helps. It stops me brooding quite so much. Have you had lunch? Aggie Williamson keeps bringing me food. Either things she made or wonderful little goodies Martin’s cooked, but I can’t face eating.’

And Fran saw that she did seem to have lost weight. Her eyes were hollow and her cheekbones angular beneath the fine skin. She had put on make-up though, a very subtle foundation, a smudge of shadow on her eyes. I would do the same, Fran thought. It would keep me from falling apart altogether.

Bella was continuing. ‘Shall we have tea then? And perhaps a slice of cake. Do you mind sitting in the kitchen?’

Fran was reminded of the last time they’d sat here, discussing the fake notices which had been circulated to cancel the exhibition. How fierce and angry Bella had been then. How important the launch had seemed.

‘Do the police know yet why Jeremy Booth put out all those flyers?’ she asked.

‘Surely you’d know that better than me.’ For a moment it was the old Bella, amused, sharp. ‘Haven’t you taken up with Jimmy Perez?’

‘He doesn’t discuss the case with me.’

‘I’ve been trying to think where I might have met Booth,’ Bella said. ‘I’ve been thinking a lot about the past in the last few days. It’s suddenly become sharper, somehow more vivid. It’s more pleasant than the present, and with Roddy gone there’s really not much future left. Nothing worth caring about, at least. It is possible that I knew him.’

‘There’s your work.’ That would hold me together, Fran thought. That and the pride of keeping up appearances.

‘Oh yes, there’s always that.’

‘Any idea where you might have met Booth?’

‘There were occasional visitors,’ Bella said vaguely. ‘People who drifted into my life for a few weeks and then disappeared. Students and other artists. I liked the energy of the people who came and sometimes I asked them to stay. I’d bought this big house. And I loved parties. Just like your ex-husband, my dear. So why not?’

‘You think Booth might have been one of your stray guests?’

‘Perhaps.’ She nibbled at a piece of fruit cake. ‘I think Peter Wilding might have been one of them too. I hadn’t realized before. It’s only since Roddy died, this strange escape into the past, living the old days in my head. If it’s the man I’m remembering, he doesn’t even look very different. But the summer I believe he was here wasn’t a very happy time for me. I’ve been trying since then to put it out of my mind. Besides, I can’t be sure.’ She seemed to realize she was rambling, looked up and gave a quick, wicked smile. ‘Will you pass all this information on to Jimmy Perez?’

‘Would you rather I didn’t?’

She gave a shrug. ‘Just tell Jimmy I can’t be certain. And Wilding never mentioned having been here. That does seem odd, doesn’t it? When he first started writing to me, telling me how much he enjoyed the paintings, he didn’t bring that up. His letter was very flattering, of course. We all enjoy being flattered. But you’d think he’d say something, wouldn’t you, if he’d been a guest in my house? Something self-deprecating and hopeful. I don’t suppose you remember but you were kind enough to put me up one summer. I’m not sure how accurate my memories are. It could all be make-believe. I think grief makes everyone a little bit mad. That and the simmer dim.’

‘Do you think Jeremy Booth and Peter Wilding were here at the same time?’

There was a long silence before Bella answered.

‘You know, I rather think they were. It was this time of the year. An unusually warm summer. The house was full. Roddy’s parents were still living in Lerwick then, but he came over to see me most weekends and there were a couple of weeks when Alec was away in hospital. I remember swimming with him from the beach here. I taught him to swim. There aren’t many days when it’s warm enough to do that. And at night we had parties on the beach. Bonfires and music. There was usually someone who could play. Too much drink and too much dope. It was long after the sixties, of course, but perhaps we were trying to recreate that sort of sense. The creativity and the freedom. We wanted to believe that we were young.’ She paused. ‘And I was in love, with Lawrence Thomson. I’d been in love with him since I was thirteen. Probably before that. I remember playing kiss-chase with him in the little school in Middleton. All these people who stayed, none of them could match up to him.’
