‘Are you planning to sleep here?’ Erlendur asked, looking at the clock. It was well past midnight.
‘I dunno,’ Eva Lind said. ‘Would you mind reading me the chapter about your brother again?’
Erlendur looked at his daughter for a long time before getting up and going over to the bookcase. He took out the book containing the account and, taking his seat again, began to read about the incident and his father’s ineffectiveness and how he himself was described as gloomy and withdrawn and how he had searched for his brother’s remains. He glanced over at his daughter when he had finished reading. He thought she had fallen asleep. Putting down the book on a small table beside the sofa, he sat with his hands in his lap, thinking how angry his mother had been with the man who wrote the account. A long time passed, until Eva Lind eventually sighed.
‘You’ve been trying to keep him alive ever since,’ she said.
‘I don’t know if…’
‘Isn’t it time to let him die?’
Eva Lind opened her eyes and, turning her head, fixed her father with her stare.
‘Isn’t it time you let him die?’ she asked again.
Erlendur still did not answer.
‘Why are you interfering in this?’ he asked at last.
‘Because you’re unhappy, probably even unhappier than me sometimes,’ Eva Lind answered.
‘I don’t know if it’s anything to do with you,’ Erlendur said. ‘It’s my business. I do what I have to.’
‘Then go out east or wherever it is you were born. Go out there and do what you have to do. Get rid of him and free yourself. You owe it to yourself after all these years. And him too. Let him die. You owe it to yourself and to him. You have to free yourself from him. You have to free yourself from this ghost.’
‘Why are you interfering in this?’ he repeated.
‘Says you who can never leave anyone alone.’
They were both silent for a while until Eva Lind asked if she could sleep on the sofa since she couldn’t be bothered to go home.
‘Be my guest,’ Erlendur said. ‘Sleep here.’
He stood up to get ready for bed.
‘If I ever needed to, I did it ages ago,’ Eva Lind said, turning her face into the corner of the sofa.
‘Needed to what?’
‘Forgive you,’ she said.
Erlendur was startled out of his reverie by the sound of a car stopping in the drive. A door opened and he heard footsteps on the gravel outside, coming in the direction of the boat shed. Daylight shone in through two little windows, one on each side, illuminating the dust motes in the air. Outside he could see the sunlight gleaming on Lake Thingvallavatn, which was as smooth as a mirror in the still autumn weather. The door opened and Baldvin stepped inside, closing it behind him. There was a slight pause before the light came on overhead. Baldvin didn’t notice him at first and Erlendur saw him search for something, then bend down and straighten up again with the defibrillator in his arms.
‘I thought maybe you weren’t coming,’ Erlendur said, rising from the corner where he had been sitting, and stepping into the light.
Baldvin started, almost dropping the machine.
‘Christ, you startled me,’ he gasped, before regaining his composure and trying to put on a show of anger and outrage. ‘What…? What’s this supposed to mean? What are you doing here?’
‘Isn’t it rather a question of what you’re doing here?’ Erlendur asked levelly.
‘I… This is my holiday home… What do you mean, what am I doing here? It’s none of your business. Won’t you… Why are you following me?’
‘I’d begun to think that you weren’t coming,’ Erlendur said. ‘But you couldn’t stand it any longer and were going to dispose of the defibrillator in a safe place. Your conscience was starting to plague you. Perhaps you’re no longer as confident of getting away with it as you were.’
‘I haven’t a clue what you’re talking about. Why won’t you leave me alone?’
‘It’s because of María; she’s haunting me like an old ghost story. There are a number of things concerning her I want to talk to you about, various questions that I know she herself would have wanted to ask you.’
‘What bullshit is this? Did you break the lock on the door?’
‘I did that the other day,’ Erlendur admitted, ‘when I was trying to fill in the gaps.’
‘What rubbish is this?’ Baldvin asked again.
‘I was hoping you’d tell me.’
‘I’m here to tidy up the boathouse,’ Baldvin said.
‘Yes, of course. And there’s another thing. Why were you using water from the lake in your hot tub?’
‘What?’
‘I took a sample from your hot tub, from the waste pipe. The water supply to the cottage and hot tub comes from the wells up the hill. It’s heated by electricity inside the cottage and then pumped into the system. So why should there be fine silt from Lake Thingvallavatn in the waste pipe of your hot tub?’
‘I don’t know what you’re talking about,’ Baldvin said. ‘We sometimes… we used to take a dip in the lake in summer and get in the hot tub afterwards.’
‘Yes, but I’m talking about a much larger volume of water. I think the tub was filled with lake water,’ Erlendur said.
Still holding the defibrillator, Baldvin backed out of the boathouse, obviously with the intention of putting the machine in the back of his car. Erlendur followed him and removed the machine from his grasp. Baldvin did not put up any resistance.
‘I spoke to a doctor,’ Erlendur said. ‘I asked him how someone would go about causing heart failure without anyone noticing. He said you’d need determination and a large amount of cold water. You’re a doctor. Do you agree?’
Baldvin stood by the boot of his car without answering.
‘Wasn’t that the method you used on Tryggvi in the old days?’ Erlendur said. ‘You couldn’t use any drugs on María. Couldn’t risk any trace being found, could you? In case they did a postmortem. The only thing you could use was a tiny dose of sleeping pills to dull the cold.’
Baldvin slammed the boot of the car.
‘I don’t know what you’re talking about,’ he repeated furiously. ‘And I don’t think you do either. María hanged herself. She didn’t sleep in the hot tub if that’s what you’re imagining. You should be ashamed of yourself!’
‘I know she hanged herself,’ Erlendur said. ‘I want to know exactly why. And just how you and Karólína persuaded her into it.’
Baldvin seemed to be ready to drive away rather than have to listen to Erlendur any longer. Going round to the driver’s door, he opened it and was about to get into the car when he paused and turned to face Erlendur.
‘I’m tired of this,’ he said roughly, slamming the door. ‘Tired of this bloody persecution. What do you want?’
He walked towards Erlendur.
‘It was Tryggvi who gave you the idea, wasn’t it?’ Erlendur said calmly. ‘What I want to know is how you two persuaded María to enter into it.’
Livid with rage, Baldvin glared at Erlendur who stared back.
‘ “You two”?’ Baldvin said. ‘What do you mean, “you two”?’
‘You and Karólína.’
‘Are you out of your mind?’
‘Why should you suddenly be concerned about the defibrillator now?’ Erlendur asked. ‘It’s been sitting here untouched ever since María died. Why is it so important to spirit it away now?’
Baldvin did not answer.
‘Is it because I mentioned it to Karólína? Did you get scared? Did it occur to you that you’d better dispose of it?’
Baldvin continued to stare at him without saying a word.
‘Why don’t we go and sit down in the cottage for a moment?’ Erlendur suggested. ‘Before I call for back-up.’
‘What proof do you have?’ Baldvin asked.
‘All I have is a nasty suspicion. I would really like to have it confirmed.’
‘And what then?’
‘What then? I don’t know. Do you?’
Baldvin was silent.
