I lean across the table and look at him sincerely.
'Everyone can flirt with the idea of suicide,' I say, 'but there's a big gap between thought and action. And even though you seem to think that it's a swift and easy death, I'm sorry to have to tell you that you're very much mistaken.'
'Why do you say that?'
'Because I know.'
'What do you know?'
I can't sit still any longer, I have to move. I walk softly up and down the room.
'True, exhaust fumes are very poisonous,' I say, 'but do you know how they kill?'
He shakes his head. He waits for me. His grey eyes are guarded.
'The fumes attach themselves to haemoglobin in your blood and prevent the blood from circulating oxygen. You will, in other words, suffocate from within. Literally.'
He is starting to look anxious.
'And it doesn't take a few minutes,' I say, 'it takes many hours. On your way to death you will need to go through several stages. Do you really want to know this, Alvar?'
He nods softly, he squeezes his hands in his lap.
'First you'll experience trouble breathing. You'll develop a severe migraine-like headache. Then you'll feel nauseous; your body will dispose of its stomach contents. Disorientation and hallucinations follow. Perhaps you'll start clawing at the door handle as your body desperately struggles. Before you finally pass out. Hours can pass between the time you faint and your actual death. When you're found your airways will be filled with foam. Your lungs will turn into two large oedemas, as will your brain. And you'll be found in your own vomit. There will not be much left of the imposing man you once were. In other words, you won't die in your sleep, you'll be fighting all the way until you die.'
He shakes his head in disbelief. His cheeks are pale.
'But how do you know these things?'
'I have been where you are now,' I reply.
He looks dubiously at me. 'You? Why?'
'I had my reasons,' I reply, 'and I thought they were valid. I'd done my homework carefully, I'd read all I could find on exhaust poisoning. I wanted to know how it happened, what I would have to go through. It was in March,' I continue. 'Everything stopped. I was overcome by fear, I couldn't manage anything. I couldn't eat, couldn't sleep, I couldn't even move. My fear came in violent attacks, like electric shocks.'
Alvar sits listening to me.
'I realised after a few days that I couldn't live like that, I wouldn't be able to handle it. So I got off the sofa and I went downstairs to the basement.'
'What were you keeping there?' he asks.
'A hose,' I explain. 'I brought the hose upstairs to the kitchen, where I kept a roll of parcel tape in a drawer. I went out into the garage to my Mercedes. Then I squatted down and examined the exhaust system. Inside the pipe itself were two smaller pipes and I went back inside and cut the hose into two equal parts of approximately three metres each. Then I went back to the car. I opened the window on the driver's side very slightly. I attached the hoses to the exhaust pipes, trailed them along the car and fed them through the gap in the window. Then I went about sealing every crack, so the inside of the car would be airtight. My plan was to achieve the highest concentration of the exhaust fumes in the shortest possible space of time. And given that the risk of vomiting is relatively high I decided to stop eating in the time I had left, because the thought of being found in a pool of my own vomit was unbearable. When the hoses were properly attached to the exhaust pipe and the window had been sealed, I went back into my house and upstairs to my bedroom. I took my duvet and my pillow and carried them to the car. I reclined both seats and arranged the bed linen as neatly as I could. I wanted to create the illusion that I was dying in my own bed. Because that's ultimately what we all want, isn't it?'
Alvar's eyes widened.
'Then I selected some music,' I told him. 'K. D. Lang would sing "Hallelujah". It was the most beautiful song I could think of. I inserted the CD into the player. Then I returned to the flat, it was late morning. I fixed a time,' l continued. 'My exit would be at three in the morning. In other words, it was only a matter of hours. The seconds ticked by quickly. I found a bottle of whisky and started drinking as I counted the minutes. It was so dark everywhere, in my mind, in my living room, I could barely see the furniture. I could see no future. It was like being in a tunnel that was growing more and more narrow. I took off my watch and put it on the coffee table. Next to it I put my credit cards, one Visa and one Mastercard. Then I let myself flop down again and drank more whisky. My fear was now so powerful that it occurred to me that I might have severe difficulties actually getting to the car because my legs would be unable to carry me. Ah, well, I thought, I'll just have to crawl. Crawl across the gravel on the drive to my final resting place. And because my fear came in bursts, I needed to act quickly. I had to leave the house between fits, if I was to get into the car at all.'
I stop speaking. Alvar looks at me across the table.
'But here you are,' he says. 'What happened?'
'I drank whisky all afternoon and evening,' I tell him. 'It dulled some of my pain, but it strengthened my resolve to kill myself. Everything felt right and inevitable. I was committed to a course of action, I could not stop. I kept looking at the hands of the clock. When it was ten in the evening, I thought: now I've got five hours left. Three hundred minutes. They passed quickly, I tell you. The fear of death nearly suffocated me, I was so terrified I could taste blood in my mouth. And even though I was lying on this sofa, in this room,' I say, 'the room seemed as small as an attic.'
Alvar nods earnestly.
'Then,' I tell him, 'the telephone rang.' I nod in the direction of my desk, where the telephone is. 'The telephone rang, and I was so startled that I nearly ended up on the floor. It rang angrily as if it was urgent. I staggered over and stared at it. It rang a third time, a fourth, a fifth, I couldn't see who it was, the number was being withheld. But there is something about a ringing telephone, it's impossible not to answer it. I had the chance to hear a voice, be connected again to life and other people. So I answered it.'
'Who was calling you?' he asks breathlessly.
'A friend,' I say. 'A very dear friend. "How are you?" he asked.
' "I'm in a very bad way," I replied. "I'm going to end it all at three o'clock tonight."
'It went silent down the other end. I could hear he was thinking.
' "You can't stop me," I said. "I can't take it any more."
'He was still thinking because he is a wise man. He weighed his words.
"I can tell from your voice that you are serious," he said. "But there's something I want you to do for me."
'I held the telephone close to my ear and listened to his reassuring voice. "And what would that be?" I asked anxiously.
'"That you postpone it," he said. "That you grant yourself another day, and that you'll come over and see me tomorrow. We'll go for a walk in the woods. You ought to allow yourself that. You deserve another day."
'I clutched the telephone and thought about what he had said. A walk in the woods. I glanced out at the drive, towards the garage. Where my Mercedes had been turned into a gas chamber.
' "Are you there?" he asked.
' "Yes," I whispered.
' "Is that a promise?"
'I had to support myself on the desk with my other hand. "Yes, I'll be there."
' "I'm trying to get you to agree to something. Will you come over tomorrow?"
' "Yes," I said dully.
' "Are you sure?" he asked.
' "Absolutely," I replied. At that moment I felt that something had changed inside my chest. It felt as if a warm substance was trickling down it, as if something was melting.
' "Then I expect you to come," he said. "I'll be waiting for you. If you kill yourself tonight, I will feel that you have let me down. And you don't want to let down a good friend, do you?"
'I considered what he had just said. No, I didn't want to let him down. The feeling of warmth continued to spread through my body.
