'What is it, Magnus?'

'A dream, that's all.'

'A bad dream?'

'Uh huh.'

'Tell me about it.'

'No, it's OK.'

'Magnus, I want to know about your bad dreams.' She pulled herself up on one elbow, her breasts shadows in the weak light seeping in from the curtains. He could make out a half smile of concern. She touched his cheek.

So he told her. About the dream, the 7-Eleven, O'Malley, the dopehead. And about the alleyway, the garbage cans, the fat bald guy, and the kid, the kid who Williams had said had just died.

She listened. 'Do you get these dreams a lot?'

'No,' Magnus said. 'Not until very recently. That second shooting.'

'But they were trying to kill you, weren't they, those two men?'

'Oh, yeah. I don't feel guilty about it at all,' said Magnus. 'At least, not while I'm awake.' He slammed his fist into the mattress. 'It doesn't make any sense. I don't know why I let it bother me.'

'Hey, you killed someone,' Ingileif said. 'You were absolutely right to do it, you had no choice, but you feel bad about it. You wouldn't be human if you didn't, and you are human, even if you think you are a big tough cop. I wouldn't like you if you weren't.'

And she snuggled up into his chest. He pulled her tightly to him.

They kissed.

He stirred.

Afterwards she fell right back asleep. But Magnus couldn't. He lay still, on his back, staring up at the ceiling.

She was right about the dreams, of course. He should expect them, accept them. The idea lulled him.

But then he thought of Colby, hiding out somewhere, God knows where, fearing for her life. Shouldn't he feel guilty about her?

He glanced over to Ingileif, her eyes closed, breathing gently in and out through half-open lips. Even in the gloom he could make out the nick in her eyebrow.

Colby had made it pretty clear that there was little chance of salvaging their relationship. In fact, a one-night-stand with a beautiful Icelandic girl was a perfectly sensible way to get over her. Much better than getting blind drunk and winding up in jail. Trouble was, looking at Ingileif lying beside him, it didn't feel like a one-night stand at all. He really liked her. Really liked her.

And for some stupid reason that made it a much worse betrayal of Colby.

After driving back from Hruni they had stopped at the only hotel in Fludir. It turned out to have a very good restaurant. They had eaten a long leisurely dinner, watching the valley of the Hvita submerge into darkness in front of them. They had walked back to Ingileif's house along the smaller river that ran through the village, and then they had wound up in Ingileif's childhood bedroom.

He smiled at the memory.

He was being ridiculous. He had been in Iceland for less than a week, and already he was beginning to understand that the Icelanders had a more casual attitude to sex than he was used to. He was just like, what's-his-name, the painter, Ingileif's alibi. Sure she liked him, just like she liked skyr or strawberry ice cream. Maybe less.

He had to be careful here. Sleeping with a witness was a definite no-no in America, and somehow he doubted that Baldur would be impressed if he ever found out. And could he be entirely sure that she was innocent?

Of course he could.

But the detective in him, the professional, whispered something else.

CHAPTER TWENTY-SEVEN.

THIS TIME, THE pastor of Hruni was in.

He came to the door, an imposing man with a large bushy beard and big black eyebrows. He frowned when he saw Magnus, but his expression changed when his eyes rested on the detective's companion.

'Ingileif? Goodness me, I haven't seen you since your poor mother's funeral. How are you, my child?' The pastor's voice was a pleasant rich baritone.

'I'm very well,' said Ingileif.

'And to what do I owe this pleasure?'

Magnus spoke up. 'My name is Magnus Ragnarsson and I am attached to the Reykjavik Metropolitan Police. I'd like to ask you a few questions, if I may. May we come in?'

The pastor pulled together his mighty eyebrows. 'I was expecting a visit from you,' he said. 'I suppose you had better come through.'

Magnus and Ingileif took off their shoes and followed the pastor through a hallway thick with the aroma of freshly brewed coffee. He led them into a study, crammed full of books. In addition to a desk, there was a sofa and an armchair covered in worn chintz fabric. Ingileif and Magnus perched next to each other on the sofa, while Hakon took the chair. Magnus was surprised to notice a small collection of CDs tucked among the books, including Pink Floyd, Black Sabbath and Led Zeppelin.

No sign of any coffee. Which was pretty rude in Iceland. You always gave your guests coffee and cakes, especially if you had some brewing.

Hakon addressed Ingileif. 'I must confess I was expecting another visit from the police. But I don't understand why you are accompanying them?'

'Ingileif is concerned about the death of her father,' Magnus said.

'Ah, I see,' said the pastor. 'It is natural to have questions, especially since you were so young when the tragedy happened. Although I still don't see why you would want to ask them now. And in the presence of the police.'

'You know we have your son in custody?' Magnus said.

'Yes, I heard it on the radio. You have made a mistake there, young man. A terrible mistake.' Deep-set eyes glowered at Magnus. Although an imposing man, the Reverend Hakon seemed younger than Magnus imagined. There was some grey around his temples, and some lines along his forehead, but he looked closer to forty than to sixty.

'He is being interviewed at Police Headquarters in Reykjavik right now,' said Magnus. 'And I'm sure that my colleagues will want to talk to you once they have finished speaking with him. But in the meantime, tell me what happened on the trip you and Dr asgrimur took the weekend he died.'

The pastor took a deep breath. 'Well, there was a police investigation of course, and I spoke to them at length. I'm sure you could look up the file. But to answer your question. It was early May. Your father and I had worked throughout the winter on a project.' He glanced inquiringly at Ingileif.

'Magnus has read Gaukur's Saga,' said Ingileif. 'And he knows that my grandfather claims to have found the ring and hidden it again.'

This information caused the pastor to pause a moment while he collected his thoughts. 'Well, in that case you know as much as me. Using my knowledge of folklore, together with the clues in the saga, such as they are, we drew up a list of three or four possible hiding places for Gaukur's ring. This was our second trip of the season, and it was a glorious day. We didn't check the weather forecast, although we should have done, of course.

'A few years before, I had read an old nineteenth-century history of Icelandic folklore, in which I stumbled across a little-known local legend about a ring hidden in a cave guarded by a troll. It was a variation on the old story of a shepherd girl meeting a hidden man or an elf and going off with him, despite the opposition of her family. That theme is quite common in these stories, but the ring was unusual. The location of the cave is identified in the story, so we took a tent and hiked out there.'

Magnus recognized the story of Thorgerd from the pastor's old notes in the doctor's papers at Ingileif's house.

The pastor sighed. 'It was more of a hole in the rock, really. And there was nothing in it. We were disappointed and we camped about a mile away, by a stream. It snowed in the night you know, one of those sudden storms you get in May that come out of nowhere and it was still snowing when we got up. We took down our tent and headed home. The snow thickened, it became difficult to see. Your father was walking a few metres ahead of me. We were both tired, I was just staring at the ground in front of me, one step at a time, when I heard a cry. I looked up and he had disappeared.

'I realized that we were on the rim of a cliff, and he had slipped over. I could see him about twenty metres down, lying at an odd angle. I had to move a fair distance along the cliff top to find a route down, and even then it was very difficult in the snow. I slid and fell myself, but my fall was cushioned by the snow.'

The pastor paused and fixed Ingileif with his deep-set dark eyes. 'When I found your father he was still alive, but unconscious. He had hit his head. I took off my own coat to keep him warm, and then rushed off to find help. Well, "rushed" is hardly the word for it in the snowstorm. I should have taken it more slowly: I got lost. It was only when the snowstorm ceased that I saw a farm in the distance. I was very cold by then remember I had given my coat to your father.'

'The farm was alfabrekka?'

'That's right. There were two farmers there, a father and a son, and they both came back with me to look for asgrimur, while the farmer's wife called mountain rescue. By the time we got to your father, he was dead.' The pastor shook his head. 'When the rescue team eventually arrived they said he had been dead for a while, but I still wish I hadn't got myself lost in the storm.'

'Did the police find any evidence that the doctor's death wasn't accidental?' Magnus asked.

'Of course not!' the pastor protested, his voice booming. 'You can check on the file. There was never any doubt about that.' The pastor glared at Magnus, commanding him to accept his assertion. Magnus didn't flinch. He would make up his own mind.

He was beginning to understand what Ingileif had meant when she said the pastor was creepy. The man had an aura of power about him that reached out towards Magnus, urging him to bend to his will.

It was a power that Magnus was determined to resist.

'Did you continue looking for the ring after my father's death?' Ingileif asked.

The pastor turned to her and relaxed slightly. 'No. I let all that drop. I must confess it was fun working on the puzzle with your father, but once he had died then I lost all interest in the ring. Or the saga.'

Magnus glanced at the walls. There were three different prints of a volcano erupting. Hekla. 'So how do you explain those?'

'I have made quite a study of the role of the devil in Icelandic ecclesiastical history,' said Hakon. 'Hekla was known throughout Europe as the mouth of hell. That, as you can imagine, intrigues me.'

He paused. 'I must admit that from that point of view, Gaukur's Saga is very interesting. As far as I am aware it is the earliest mention of Hekla in that role. And also the first recorded ascent of the mountain. Until now we thought that no one dared climb Hekla until 1750. But of course isildur and Gaukur were climbing it before the big eruption of 1104, so perhaps it wasn't quite so frightening then.'

'You spoke to my colleague a few days ago about a visit here by Professor Agnar Haraldsson,' Magnus said.

'That's true.'

'And what did you tell her he wanted to speak to you about?'

The pastor smiled, a mass of wrinkles appearing around his eyes. 'Ah, I wasn't entirely honest with your colleague. I take the confidences of my parishioners very seriously.' He looked pointedly at Ingileif.

'So what did Agnar really talk to you about?'

'Gaukur's Saga, of course. And the ring.' The pastor pulled at his beard. 'He told me that Ingileif had asked him to act for the family in the sale of the saga.' He frowned at Ingileif. 'I must admit that I was quite shocked by this. After all the years that the family had successfully kept the saga a secret. Centuries even.'

Ingileif reddened at the admonition from her pastor.

'I hardly think that's for you to judge,' said Magnus. 'In fact, you should have told my colleague the truth first time around. It would have saved a lot of people a lot of time.'

'asgrimur was a very good friend of mine,' said Hakon sternly. 'I know what he would have wanted me to do.'

'What you did was obstruct a murder inquiry,' said Magnus. 'Now. Did Agnar have something specific to ask you?'

'Ingileif had just discovered the letter to her grandfather from Tolkien which referred to the discovery of the ring. Agnar came straight here and asked me much the same questions as you did just now. I gained the very strong impression that he wanted to try to find the ring himself. Of course, I couldn't help him.'

'How did he behave?' Magnus asked.

'Agitated. Excited. Aggressive in his questioning.'

'Did you tell him anything you didn't tell us?' Magnus asked.

'Absolutely not.'

Magnus paused, examining the pastor. But the man wasn't about to say any more. 'See, the day after he saw you, Agnar sent a message which implied that he knew where the ring was.'

'Well, he certainly didn't seem to know when I saw him.'

'Did you tell him where you looked for it that day in 1992?'

'No. He asked, but I told him I couldn't remember. But of course I can.'

Ingileif showed the pastor the map that she had found among her father's papers. 'Is that the place?'

Hakon peered over. 'Yes, that's it. And there's the farm, alfa-brekka. I suppose I could have told Agnar where it was, wasted his time. I'm sure the ring is not there. At least it wasn't there seventeen years ago, and I doubt it could have got there since.'

'Are you certain it wasn't there?' Magnus asked. 'I wonder if Agnar discovered clues to the location somewhere else and found something you missed.'

'I'm absolutely certain,' said Hakon. 'Believe me, asgrimur and I scraped every inch of the cave, and it wasn't very big.'

'Did your son know anything about this?' Magnus asked.

'Tomas? I don't think so. He was, what, thirteen at the time? I didn't tell him about the saga or the ring either then or afterwards. Did you, Ingileif?'

'No,' said Ingileif.

'Then why was he speaking to Agnar the day he died?' Magnus asked.

Hakon shook his head. 'I don't know. I had no idea they knew each other.'

'Interesting coincidence, don't you think?'

Hakon shrugged. 'Maybe. I suppose so.' Then he leaned forward, his eyes boring into Magnus. 'My son is not a killer, young man. Remember that.'

'God that man gives me the creeps,' Ingileif said as they drove back towards Reykjavik.

'Was he always like that?'

'He was always weird. We didn't go to church much, but when we did his sermons always used to scare the wits out of me. Lots of fire and brimstone, the devil behind every rock. As you can imagine, hearing that sort of thing while you are actually sitting in Hruni church is pretty frightening for a kid.'
