'OK. Who?'

'Peder Aksden. Tolmar's father. The letters are a record of his life, from sixteen to thirty.'

'A record?'

'Ja. Everything about him. What work he did on his parents' farm. The girls he dated. The books he read. His hobbies. His opinions. His health. His... personality.'

'That's crazy. Why would Peder Aksden's uncle write letters about all that to a retired British policeman?'

'They're not really letters to a friend, Henning. They're reports. For posterity.'

'Why should... posterity... be interested in Peder Aksden?'

'Good question. Listen to this.' Kjeldsen gestured to Eusden for permission to handle the letters. He was behaving meekly and contritely, like someone who accepted that the game was up or like someone secure in the knowledge that he had the ace of trumps up his sleeve. 'Is it OK... if I read to you from one?'

'Go ahead.'

Kjeldsen eased out a letter from the stack, checked the date, then pulled it free. 'November, 1938. Nydahl is worried about Peder's engagement to a local girl. This is what he says. Henning can translate for you, Mr Eusden.'

Kjeldsen read the words in Danish, pausing at intervals to allow Norvig to catch up in English. 'He is determined... to marry Hannah Friis... in the spring... Oluf and Gertrud are worried... and want me to decide...if I should stop him...I remember you and I discussed... the problems a family might cause... and whether we should ever allow him... to have one.' At that Kjeldsen stopped reading and slid the letter back into place.

'What "problems" is he talking about?' asked Eusden.

Kjeldsen smiled thinly. He seemed to be growing more confident, despite the lack of obvious cause.

'They emerge when you work your way through the letters,' he replied enigmatically.

'Why don't you just tell us?' demanded Norvig.

'There's not enough time.'

'Bullshit.' Norvig leant across the desk and looked Kjeldsen in the eye. 'We've got all night.'

'No. I'm supposed to meet the buyer in less than an hour. I'm already supposed to have phoned him to find out where.'

'Bad luck.'

'For you also, Henning. And for you, Mr Eusden. Very bad luck. I'd be willing in the circumstances to share the proceeds with you.'

'There's not going to be a sale,' Eusden declared, reaching for the case.

But Kjeldsen was quicker. He grasped the handle tightly and declared bluntly, 'Twenty million kroner.'

For a second, no one moved or spoke. Kjeldsen looked at Norvig, then at Eusden. He moistened his lips with his tongue.

'Twenty million kroner,' he said softly. 'A little over two million pounds at the current exchange rate. That's the price I've agreed. So, what do you say, gentlemen? Is it still no sale?'

'Who's your millionaire buyer?' demanded Norvig.

'It's safer if you don't know.'

'It's never safer for me not to know something.'

'In this-'

The burbling of Kjeldsen's mobile, which lay on the desk next to the case and began circling on its axis as it rang, cut him off. He looked enquiringly at Norvig and Eusden.

'My buyer must've got tired of waiting for me to call.'

'Let him go on waiting,' said Eusden. He pushed the lid of the case down and let his hand rest on the rim, a few inches from Kjeldsen's grip on the handle.

'If I don't answer, he'll send his people to look for me.'

'Answer it,' said Norvig.

Eusden glanced round at him suspiciously, wondering for the first time whose side the journalist was on. Norvig shrugged.

Kjeldsen picked up the phone. 'Ja?... No, there's nothing wrong.' He was speaking English, Eusden noticed, not Danish. Perhaps that meant his buyer was not Danish. 'OK.' Kjeldsen let go of the case, grabbed a pencil and scrawled something a single word on a notepad. 'OK... Yes, I can find it... I understand... See you there.' He rang off and glanced at his watch. 'I'm due to meet them in half an hour.'

'You can meet them whenever you like,' said Eusden. 'But you're not taking this with you.' He swung the case round and grasped the handle.

'Hold on.' Norvig slammed the flat of his hand down on the lid of the case. 'Let's all just... take a moment.'

'Good idea,' said Kjeldsen, sounding like the very embodiment of honey-toned reason. 'Twenty million kroner in cash is something to take a moment to think about, no? A lot of problems solved. A lot of pleasures bought. Ours to share three ways.' He glanced at Norvig. 'Or two.'

'This case belongs to Marty Hewitson,' Eusden declared. 'There's no-'

'What do the letters tell us, Anders?' put in Norvig. 'What exactly do they tell us?'

'A secret. With a twenty million kroner price tag on it. Ten for you. Ten for me. The clock's ticking, Henning.'

'I'm taking this,' said Eusden, tugging at the case. 'Don't try to-'

The blow took him unawares. Norvig's fist landed sideways under his jaw, jerking his head back. He staggered away from the desk, the case no longer in his grasp. Before he had recovered, Norvig was between him and the desk.

'I can't let you fuck this up for me, Richard,' he shouted, pushing him against the wall. 'Twenty million's too much to say no to.'

'The case isn't yours to sell,' Eusden gasped. He was pinned by the shoulders and unable to move. Norvig was evidently stronger than he looked. 'You agreed to help me.'

'I am helping you. Give it up, Richard. Take your share.'

'I don't want a share of anything.'

'Then take nothing. It's up to you.'

'You bastard.'

'Karsten's dead. Your friend Marty's probably dead too. It's time to get smart. Time to cash in.'

'Let go of me.'

'OK.' Norvig released him. 'OK.' The journalist took a step back. He was breathing through gritted teeth. A rivulet of sweat was trickling down his temple. There was sorrow in his gaze. But it was not enough. Every man has his price. And Norvig's was on the table. 'Like you say, Richard, I agreed to help you. But now I'm helping myself. Don't try to stop me.'

'Give me that case.' All Eusden could cling to was a stubborn assertion of his rights as Marty's representative. He lunged towards the desk. Kjeldsen grabbed the case and jumped up from his chair.

Suddenly, Eusden's leading foot was whipped from under him. Norvig added a shoulder barge to the trip. Caught off-balance, Eusden fell. He glimpsed the shadow-etched rim of the desk, closing fast, as he pitched sideways. Then... nothing.

TWENTY-SIX.

Eusden was swinging gently in a hammock. His head ached. A glaring sun threatened to dazzle him if he opened his eyes. He did not know where he was, except that it was pleasanter by far than the alternative he sensed he would become aware of if he roused himself. Something was pushing him, setting off the sway of the hammock. His head throbbed. The threatening sun turned cold. His recent memories began to reassemble themselves into a more or less coherent knowledge of time and place. Then full recollection flooded into his mind like blood into a starved limb. He opened his eyes.

A slightly built, sad-faced Asian man in a boiler suit, wearing a baseball cap with the New York Yankees logo on it, stopped nudging him with the toe of his grubby trainer and stared down at him. He said something in oddly accented Danish. Eusden could only respond with a groan.

He pushed himself up on one elbow and blinked about him. They were on the landing outside Kjeldsen's office. There was the door to his right, firmly closed, and the sign: A. KJELDSEN, ADVOKAT. Pallid overhead light fell on the bare walls and floor and the nervous expression of the man in the boiler suit the office block's caretaker, presumably who repeated what he had just said, to no more comprehensible effect.

'Do you speak English?' Eusden asked, in a slurred voice he hardly recognized as his own. There was a smell of whisky in the air and it seemed to be coming from him. His gaze drifted to an empty bottle of Johnnie Walker lying by his elbow. It looked like Kjeldsen had raided his filing cabinet supply of the hard stuff to set him up as a drunken intruder. No doubt his appearance fitted the bill. He raised a hand to what felt like the epicentre of his headache. The area around his left eyebrow was damp and tender. The dampness, he saw as he withdrew his hand, was blood. A hazy memory of being dragged to where he now lay floated to the surface of his turbid thoughts. He looked at his watch, focusing on the dial with some difficulty, and was surprised to see that only twenty minutes or so had elapsed since Norvig had turned on him. 'Do you speak English?' he asked again.

'Yes.' The caretaker frowned down at him. 'You should not be here.'

'I expect you're right there.' Eusden levered himself slowly and painfully to his feet, the caretaker taking an apprehensive step back as he did so.

'I must phone the police if you are not leaving now.'

Eusden stooped forward as a wave of nausea swept over him. It did not return as he stood upright again. But his head throbbed painfully. Anger stirred within him. He had been as stupid to trust Norvig as Marty had been to trust Kjeldsen. They were both as treacherous as each other. And they had played him for a fool. They were at the rendezvous now, waiting for their fat pay-off, dreaming of how they would spend the money. If only he could catch up with them, he might still retrieve the situation, though how he could not imagine. Besides, he did not know where the rendezvous was. There was nothing he could do. Except- 'Please go, mister. I'm not wanting any trouble.'

'Nor me. But I've got it. In spades.'

'I cannot help you.'

'Actually, you can. I need to get into this office.' Eusden pointed to Kjeldsen's door. 'I bet you've got a pass key.'

'I cannot let you in there.'

'Sorry...' Eusden bent down, picked up the empty whisky bottle by the neck and smashed it against the wall. The caretaker jumped in alarm. Glass scattered across the floor. 'I'm going to have to insist.' He was between the other fellow and the stairs. He had blood on him and reeked of alcohol. He probably looked like a man it was unwise to defy. 'Open the door.'

'I cannot do that. I will be losing my job.'

'Better than losing your life.' Eusden held the broken bottle in front of him like a weapon. He could not believe he was behaving like this. But he would achieve nothing with politeness and appeals to reason. The caretaker was frightened. And his fear was Eusden's only hope. 'Open the door.'

'Please, mister. I-'

'Open it.'

'OK, OK.' The caretaker gestured submissively and fumbled in his pocket. Out came a massive bunch of keys. He sorted through them with trembling hands, sweating and breathing shallowly as he did so. Eusden hated himself for putting the man through such an ordeal. But it had to be done.

'Hurry up.'

'OK, OK. I have it.' The caretaker moved to the door, unlocked it and pushed it ajar.

'Switch on the light and go in.'

The poor fellow obeyed. Eusden followed him into the room and pulled the door shut behind them. Stark fluorescent light made the office look different. But the biggest difference was that Clem's attache case was gone from the desk.

'What's your name?'

'Wijayapala. They call me... Wij.'

'OK, Wij, just do as I say and you'll be fine. Is that clear?'

'Please, mister. Don't hurt me.'

'I won't. If you do exactly what I tell you.'

'Yes, yes, I will.'

'Go over to the desk and sit down in the chair.' Eusden prodded Wij between the shoulderblades and he started moving.

They reached the desk. Wij walked slowly round behind it and sat down.

'Turn on the lamp.'

Wij reached up and engaged the switch. A pool of mellower light spread across the desktop.

The notepad was where Kjeldsen had left it. And he had not bothered to tear off the sheet he had written on. Careless of him and considerate. Eusden did the tearing off instead. Marmorvej was the word Kjeldsen had scrawled. 'Yes,' he had said, 'I can find it.' So, the location had not been instantly familiar to him. And to confirm that, lying on the desk where it had not been lying before, was a Copenhagen street atlas. Eusden slapped the sheet of paper down in front of Wij. 'Find that street in the atlas,' he ordered, hardening his tone as well as his heart.

Wij's general state of alarm turned the exercise of consulting the index and finding the right page into an agony. But Eusden could not do it himself without putting down the bottle, at which his captive kept casting anxious glances, so he had no choice but to stick with it. Eventually, after several long, uncertain minutes of searching and squinting, Marmorvej was located. Wij's trembling finger pointed to the spot: a dockside street away to the north, beyond the Citadel.

Eusden snatched the atlas and shoved it into his pocket. Marmorvej was probably no more than a couple of miles off but he certainly did not have time to walk there. 'How do you get here from home?'

'Sorry?'

'How do you travel?'

'Oh, on my... my scooter.'

'Where is it?'

'Down in the yard.'

'Give me the key.'

'Oh, mister, no. I need that scooter badly.'
