‘Like I said in my statement, Adrian went back to the huts when I left. I argued, but I couldn’t stop him. So if someone did Rawson in, then it must have been him, mustn’t it?’

‘It will be for a jury to decide.’

Naomi shrugged. ‘I’m cutting my losses, anyway. Time to forget about him and move on, I think. Don’t you?’

‘Aren’t you going to make even the least effort to argue that he’s innocent?’

‘What? You expect me to stand by him? Act the loyal girlfriend for the newspapers? No way. Absolutely no bloody way. He took some money to do this, didn’t he? And he never even told me. Bastard.’

‘Did you want a share?’

‘It’s got nothing to do with me, do you hear? As far as I was concerned, it was all an accident.’

‘An accident?’

‘I had no idea what he meant to do. He let me think he was just going along with the plan. In fact, he seemed to be really into it. Like that thing with the hunting horn. He said it would be a laugh.’ Naomi shook her head. ‘He was pretty useless at it, though. He’d only learned the one call.’

‘The kill call,’ said Fry.

‘If that’s what it was. I wouldn’t know.’

Fry and Murfin watched in amazement as Naomi Widdowson walked away towards the van, accompanied by a prison escort officer.

‘Well, I’ve heard about women who care more for their horses than they do for people,’ said Murfin. ‘And I’ve just seen one.’

‘I’m not a big fan of horses,’ said Fry. ‘But, even so, I know how she feels.’

THAT EVENING, IN the CID room, Fry stood by the window. It was only a few minutes after six, but darkness was falling rapidly. Heavy clouds gathered in the sky to the west. More rain was on the way.

She had been watching the pedestrians passing by on the pavement. There was nothing unusual about any of them. They were perfectly ordinary members of the public. A young woman in a smart grey business suit, talking on her mobile; a young couple carrying rucksacks, probably early tourists; a man with a dark beard and stained jeans; two girls with magenta hair and nose studs. Ordinary, innocent passers-by.

But were they all so innocent? How many potential murderers were out there, walking the streets of Edendale? Well, wasn’t everyone a potential murderer, in the right circumstances? Or the wrong circumstances. Push any average person into a corner and most of them would cross the line, wouldn’t they?

Fry thought so. The vast majority of these people hurrying by her now probably couldn’t imagine what those circumstances would be. But some of them would. A few might have a specific victim in mind right now. Who knew what fantasies were going on in their heads; violent scenarios playing out, involving a partner, a boss, or a motorist who had just given them the V-sign. Only a tiny minority of them would ever follow through on their fantasies, or act out a violent thought. But there was no way of telling who those individuals were. It might be the man with the beard. But it could just as easily be the young businesswoman, who might be plotting bloody vengeance as she chatted on her phone.
