Elly Griffiths - The Crossing Places

Ruth thinks of Cathbad's poem 'In praise of James Agar'. She thinks of Nelson's face as he looked down at the scrawled lines. She thinks of the locked cabinet in Cathbad's caravan.

'Cathbad,' she says at last. 'Where does he come into this?'

Shona laughs, slightly hysterically. 'Didn't you know?'

she says. 'He was the postman.'

Nelson has had a tough day. But then again, he almost can't remember a time when his life didn't consist of defending himself against people who wanted him sacked, trying to motivate an increasingly depressed team and ignoring Michelle's demands to come home while at the same time trying to catch a murderer. He had thought that Scarlet's funeral yesterday must be the lowest point. Jesus, that little white coffin, Scarlet's brothers and sisters looking so shocked and vulnerable in their new black clothes, seeing Lucy Downey's parents again and feeling how he had let them down. And then having to stand up and spout all that stuff about the resurrection and the life.

He had caught sight of Ruth in the congregation and wondered if she was thinking what he was thinking: the letter writer would love this.

And then there is Ruth. He knows he shouldn't have gone to bed with her. It was totally unprofessional as well as wrong. He has betrayed Michelle, whom he loves. He has, in fact, been unfaithful on two other occasions but he comforts himself that these were brief flings which didn't mean anything. Did Ruth mean something then? She's not really his type. But, that night, he has to admit, was something else. At that moment, Ruth seemed to understand him totally, in a way that Michelle has never done. She seemed to understand, to forgive him and offer herself to him in a way that even now threatens to bring tears to his eyes. Why had she done it? What does she see in him? He's not intellectual enough for her. She likes poncy professors with theories about Iron Age pottery, not uneducated Northern policemen.

So why had Ruth slept with him? She made the first move, he tells himself for the hundredth time. It wasn't all his fault. He can only suppose that she, like him, was caught up in the horror of it all, finding Scarlet's body, telling the parents. The only escape was in simple, straightforward sex. Some of the best sex, he has to admit, that he has ever had.

He doesn't know where he stands with her now. She's not the sort who will go all soppy, declaring undying love and begging him to leave Michelle. He has spoken to her on the phone a few times and she has always seemed fine, professional and calm, despite having some scary stuff to cope with. He admires that. Ruth is tough, like him. When he saw her yesterday at the dig, she had been very cool.

He'd watched her as he approached, she was totally absorbed in her work, he was sure she had no idea that he was there. He doesn't know why, but suddenly he wanted her to look up, to wave, smile, even to rush over and fling her arms round him. Of course, she hadn't done any of these things. She had simply carried on with her job, just as he was carrying on with his. It was the sensible, adult way to behave.

He had quite a good chat with that Erik Anderssen bloke at the dig. Of course he's an old hippie, way too old to have his hair in a pony tail and wear all those leather bracelets. But still, he had told Nelson some interesting things. Turns out there's a prehistoric forest buried underneath the Saltmarsh. That's why you sometimes find odd-looking stumps of trees and bits of timber. They even found some wood that had come all the way from North America. Anderssen had also talked about ritual. 'Think of a burial,' he'd said. 'From the body to the wood of the coffin to the stone of the graveyard.' Nelson had shivered, remembering Scarlet's coffin, that little wooden box, on its final journey.

He'd come back from the dig to be met by his boss.

Superintendent Whitcliffe is a career policeman, a graduate who favours linen suits and slip-on shoes. Just standing near him makes Nelson feel shop-soiled and more than usually untidy. He has the sensation, which he remembers from school, of his hands and feet being several sizes larger than they ought to be. Still, Nelson is not about to let Whitcliffe push him around. He's a good cop; he knows it and Whitcliffe knows it. He's not going to be the scapegoat on this case.

'Ah, Harry,' Whitcliffe had said, managing to convey the message that Nelson should have been there to meet him, though he had not said he was coming. 'Been out and about?'

'Following up leads.' He was damned if he was going to add 'sir'.

'We need to talk, Harry,' Whitcliffe had said, sitting down behind Nelson's desk and neatly establishing superiority.

'We need another statement.'

'We've got nothing to say.'

'That's just it, Harry,' sighed Whitcliffe, 'we need to have something to say. The press are after our blood. You arrest Malone and then release him-'

'On bail'

'Yes, on bail,' said Whitcliffe tetchily. 'That doesn't change the fact that you've got no evidence to charge him with the murders. And without him you've got no suspects.

With all the coverage of the little girl's funeral, we need to be seen to be doing something.'

The little girl's funeral. Whitcliffe had been there, in neat black tie, saying caring, compassionate things to Scarlet's parents. But for him it was just another job, an exercise in damage limitation. He had not, like Nelson, gone home and puked his guts out.

'I am doing something,'' said Nelson, 'I've been working flat out for months. We've searched every inch of the Saltmarsh…'

'I hear you've let the archaeologists loose there today'

'Have you seen how they work?' demanded Nelson. 'They really examine every inch of ground. It's all planned, nothing missed, nothing overlooked. Our forensic teams could never match it. If there's anything to find, they'll find it.'

Whitcliffe smiled. A humorous, understanding smile that made Nelson want to smack him. 'You sound quite a fan of archaeology, Harry.'

Nelson grunted. 'Lots of it's bollocks, of course, but you can't deny they know their stuff. And I like the way they do things. It's organised. I like organisation.'

'What about this Ruth Galloway? She seems to have become quite involved in the case.'

Nelson looked up warily. 'Doctor Galloway's been a great help.'

'She found the body.'

'She had a theory. I thought it was worth testing.'

'Has she any other theories?' Whitcliffe was smiling again.

'We've all got theories,' said Nelson, standing up.

'Theories are cheap. What we haven't got is any evidence.'

All the same, he knows he can't stall Whitcliffe forever.

He will have to give a statement to the press and what the hell can he say? Malone was the only suspect, and for a while he had seemed quite promising. He fitted what Whitcliffe would call 'the offender profile'. He had links with the Henderson family, he was a drifter and he was full of all that New Age crap, just like the writer of the letters.

But then they had found Scarlet's body and there was DNA all over it. The only problem was that none of it matched Malone's. Without the DNA link, Nelson was stuffed.

He'd had to let Malone go, only charging him with wasting police time.

Scarlet had been tied up, gagged and strangled. Then someone had carried her body right out to the peat beds and buried her where that henge thing used to be. Does this mean the murderer had to know about the henge? Ruth said that there is a path, a causeway or something, leading right to the place where Scarlet was buried. Were the police meant to find her, then? Has the murderer been watching them all the time, laughing at them? He knows that the killer is often someone known to the family, someone close. How close?
