‘Teasdale will be charged with manslaughter and a few other things,’ said DCI Tailby. ‘They all admit the assault on Calvin Lawrence and Simon Bevington at the quarry. They made a good job of drawing our attention there. And, of course, there’s the dog-fighting pit.’

‘There must be more,’ said Chief Superintendent Jepson.

‘We’re quite sure there are others involved. But these people have their own sense of loyalty, too. They won’t implicate anyone else.’

‘I don’t mean more people. I mean Jenny Weston. Please tell me we can connect somebody to Jenny Weston, after all this . . .’

But Tailby shook his head.

‘Yes, I lay in wait for Jenny that day,’ Maggie had said. ‘I waited at the tower, because she always came that way. I had met her before, two days earlier, and we had argued. I was angry with her – I didn’t believe her when she said she had no idea where Ros had gone. She was my main hope, because I suspected then that there was more to their relationship. But of course I did it all wrong. I antagonized her.’

‘We don’t believe there was any relationship between them, other than a loose connection through the animal rights group. No sexual relationship. Jenny Weston and your daughter were not lovers.’

‘That’s what Jenny told me, too. As far as she was concerned, Ros was just a silly, hot-headed girl who had passed through her life and was soon forgotten.’

‘But you didn’t believe her.’

And Maggie hesitated. ‘Actually, I suppose I did.’

‘So why did you attack her? Why did you use the knife?’

‘Did I do that? But yesterday, it felt as though I’d never held a knife in my life before. No, I don’t believe I saw Jenny Weston. Either she never came to the tower, or I was too late. I didn’t see her. Not that day.’

‘You expect us to believe that?’

‘You’ll have to,’ she said. ‘I think it’s true.’

Chief Superintendent Jepson scowled angrily at his officers, his blue eyes glittering.

‘Yes, I’m afraid it is true,’ said DCI Tailby.

‘Are we sure?’

‘The shoe print over the bloodstain is much too big to be Maggie Crew’s. Or Simon Bevington’s either, for that matter.’

‘Damn.’

‘Also, some strength was needed to drag the victim into the stone circle,’ said DI Hitchens. ‘We doubt that either of them would be capable of it, or would even attempt it. Besides, there’s the missing camera.’

Jepson frowned. ‘The camera?’

‘Well, Jenny Weston had reported the dog-fights to the RSPCA,’ said Hitchens. ‘We believe she’d taken some photographs, too. She carried an auto-focus camera with her when she was on the moor. Most likely, it was in her pouch.’

‘Which was missing when the body was found.’

‘Yes.’
