‘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 attaché 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.’

‘You’ll get it back. I’ll leave it there for you to find.’ Eusden pointed to the piece of paper with the word Marmorvej written on it. ‘Now, give me the key. And hand over your mobile phone as well.’

Wij undid a couple of buttons on his boiler suit and reached into an inner pocket for his mobile and the scooter key. He laid them on the desk and Eusden picked them up.

‘I’ll need the key to the door as well, Wij. I’m afraid I’m going to have to lock you in here. Sorry, but there it is. You’ll be able to call for help from the window in the morning. Oh and unplug Kjeldsen’s phone.’ He pointed to the landline receiver. ‘I’ll also have to take that. I’ll leave it downstairs with your mobile.’

‘Why you doing this, mister? You don’t look… like a crazy man.’

‘I don’t have time to explain.’

‘I got no money for a new scooter.’

‘Don’t worry. I’ll ride carefully. Believe it or not, I am sorry.’ Eusden sighed. ‘This isn’t the start to the weekend I had planned.’

Eusden’s most recent experience of two-wheeled transport lay many years in the past and even then it had not been motorized. His wobbly ride through the mercifully empty streets of Copenhagen on Wijayapala’s scooter would ordinarily have been a nightmarish ordeal. As it was, its hazards and difficulties paled into insignificance compared with the other anxieties his mind was grappling with. Marty had vanished and Clem’s attaché case had been stolen. It had very possibly already been sold to a sinister and anonymous buyer. Certainly Eusden’s chances of preventing the sale were negligible. Logically, there was no point even trying to prevent it. So far, the attempt had involved behaving despicably as well as criminally. And he was still breaking the law by riding without a crash helmet – not to mention jumping a succession of red lights.

He could not simply give up, however. An admission of defeat at this stage would be more painful than pressing on until he had done everything he could, even if it was to no avail. The blow to his head had scrambled his thought processes and he was aware he might be acting irrationally, but he felt helpless in the grip of his determination to hit back at Kjeldsen and Norvig. One had cheated him. The other had betrayed him. He could not simply let them get away with it – and pocket their ill-gotten half shares of twenty million kroner.

The docks were separated from the city centre by a dual carriageway and a railway line. The route into them by road involved a double-back after passing Nordhavn S-tog station. This brought Eusden out on to one of the harbour basins, with a vast warehouse complex between him and Marmorvej. He left the scooter there, conscious that he could not afford to advertise his arrival with the mosquito-whine of its engine, and jogged along the narrow road between the warehouse and the dual carriageway.

Beyond lay another basin, with a huge car ferry moored at a jetty on the far side. Marmorvej was the quay to his left and he heard the thrumbling note of a boat’s engine as he turned on to it. A launch was moving away from the quayside, heading out into the harbour. And two men were walking towards a car parked in the lee of the warehouse. Widely spaced security lights cast a jumble of deep shadows and shallow reflections across the snowmelt-puddled wharf and the launch’s ghostly wake. For a second, Eusden could not be sure what he was actually seeing. His perceptions were sluggish, his reactions slow. Then the scene became clear and obvious in his mind.

The two men were Norvig and Kjeldsen. They were walking towards Kjeldsen’s Volvo. The lawyer was carrying a case that was marginally the wrong size and shape to be Clem’s. They had handed his over, of course, in exchange for this case, containing their pay-off. The buyer was leaving in the launch. Eusden was too late. It had always been likely he would be. His heart sank. He strode forward, unsure of what he meant to do but set on doing something to sour the pair’s victory.

Clunk, clunk: the doors of the Volvo slammed shut as Kjeldsen settled behind the wheel and Norvig in the passenger seat beside him. The engine coughed into action. The headlamps flared. The car was facing towards the sea, so they would not yet be able to see him. As Kjeldsen forwarded and reversed into a multi-point turn, Eusden broke into a run.

Almost at once, however, he stopped, confused by other movements and noises intruding on his senses, swifter than the manoeuvring car, louder than its muffled engine – or that of the departing launch, which by now had left the basin. An unlit motorbike sped into view round the seaward flank of the warehouse. Its rider and his pillion passenger were black-leathered, sleek-helmeted shadows. The machine closed on the Volvo, fast and dark. Eusden guessed Kjeldsen and Norvig were unaware of its approach. And he also guessed its approach spelt danger for them. ‘Look out!’ he shouted.
