‘It is somewhat premature to draw such conclusions of course, but taking that into account with what we already know, perhaps. Is that practical enough for you?’
‘Practical, yes,’ Waaler said, ‘but it’s also bad news if I read you right?’
‘Correct. Our man looks a lot like the wrong type of serial killer. The sociopath.’
Aune gave the gathering a couple of seconds to let that sink in before going on.
‘According to the American psychologist, Joel Norris, the serial killer goes through a mental process involving six phases with each killing. The first is called the aura phase where the person gradually loses their grip on reality. The totem phase, the fifth phase, is the killing itself, the serial killer’s climax, or, to be more precise, the anticlimax, because the killing is never able to fulfil the hopes and expectations of catharsis and purification that the killer associates with the taking of a life. That’s why the killer goes straight into the sixth phase, the depressed phase. This in turn leads into a new aura phase in which he builds himself up, ready for the next killing.’
‘Round and round in circles then,’ said Bjarne Moller, who had crept in unnoticed and was standing by the door. ‘Like a perpetuum mobile.’
‘Except that a perpetual motion machine repeats the operations without any changes,’ Aune said. ‘However, the serial killer goes through a process that changes his behaviour over the long term. Characterised, fortunately, by a decreasing level of control, but, unfortunately, also by an increasing level of brutality. The first murder is always the one that is most difficult to recover from and thus the so-called cooling-down period afterwards is also the longest. It produces a long aura phase in which he builds himself up for the next killing and he gives himself a good long time to plan it. If the killer has taken a great deal of care with details at the scene of a crime, if the rituals have been carried out with precision and the risk of discovery is small, it suggests that he is still at the beginning of the process. In this phase he is perfecting his technique to become even more efficient. This is the worst phase for the people trying to catch him. However, after he has killed a few times, the cooling-down periods typically become shorter and shorter. He has less time to plan, the murder scenes are messier, the rituals less neatly performed and he takes greater risks. All of this indicates that his frustration is growing. Or let me put it another way, that his thirst for blood is escalating. He loses self-control and is easier to catch. But if at this time attempts to capture him fail, he can be frightened off and he will stop killing for a while. In this way he has time to calm down and he will begin at the beginning again. I hope these examples are not too depressing?’
‘We’re surviving,’ Waaler said. ‘Could you say a little about this particular case?’
‘Fine,’ Aune replied. ‘Here we have three premeditated murders -’
‘Two!’ It was Skarre again. ‘For the time being, Lisbeth Barli is only reported missing.’
‘Three murders,’ Aune said. ‘Believe me, young man.’
Some of the policemen exchanged glances. Skarre seemed to want to say something, but then changed his mind. Aune continued.
‘The three murders have been committed with the same number of days between each one. And the ritual of mutilation and decorating the body has been carried out in all three cases. He cuts off one finger and compensates by giving the victim a diamond. Compensation is, by the way, a familiar feature with this kind of brutality, typical of killers who have been brought up according to strict moral principles. Perhaps this is a lead you can follow up since there is not much morality left in homes around Norway.’
No laughter.
Aune sighed.
‘It’s called gallows humour. I’m not trying to be cynical and my points could probably be better made, but I am trying not to let this case bury me before we have even started. I recommend you do the same. Anyway, in this particular case, the intervals between the killings and the fact that rituals are being performed indicate self-control and an early phase.’
Someone cleared their throat gently.
‘Yes, Harry?’ Aune said.
‘Choice of victim and place,’ Harry said.
Aune rubbed his index finger against his chin, considered for a moment and nodded.
‘You’re right, Harry.’
Others round the table exchanged enquiring looks.
‘Right about what?’ Skarre called out.
‘The choice of victim and place suggests the opposite,’ Aune said. ‘That the murderer is moving quickly into the phase where he loses control and begins to kill indiscriminately.’
‘How so?’ Moller asked.
Harry talked without looking up from the table.
‘The first shooting, of Camilla Loen, took place in a flat where she lived alone. The killer could go in and out without any risk of being caught or identified. He could carry out the killing and the rituals without being disturbed, but he’s already taking chances when he goes for the second victim. He kidnaps Lisbeth Barli in the middle of a residential area, in broad daylight, probably using a car, and obviously a car has a number plate. The third killing is of course a pure lottery – in the ladies’ lavatory in an office area. True, it’s after normal office hours, but there are so many people around that luck has to be with him if he’s not to be caught or at least identified.’
Moller turned towards Aune.
‘So what’s the conclusion?’
‘That we can’t conclude anything,’ Aune said. ‘The most we can assume is that he is a well-integrated sociopath. And we don’t know whether he’s about to go bananas or whether he is still in control of himself.’
‘What can we hope for?’
‘One scenario is that we are about to witness a bloodbath, but there is a chance that we might nab him as he’ll be taking risks. The other scenario is that there will be longer intervals between each murder, but all our experience tells us that we will not manage to capture him in the foreseeable future. Make your own choice.’
‘But where shall we begin to look?’ Moller asked.
‘If I believed my statistics-minded colleagues I would say among bedwetters, animal tormentors, rapists and pyromaniacs, particularly pyromaniacs. But I don’t believe them. Unfortunately I have no alternative idols, so I suppose the answer is: I have no idea.’
Aune put the top on his marker pen. The silence was oppressive.
Tom Waaler jumped up.
‘OK, folks. We’ve got a bit to do. To begin with, I want everyone we have talked to so far to be interviewed again. I want all convicted murderers checked out and I want a review of all the criminals who have been convicted of rape or arson.’
Harry observed Waaler as he delegated assignments, noted his efficiency and self-assurance, the speed and flexibility with which he dealt with relevant, practical objections, his strength of mind and decisiveness when the objections were not relevant.
The clock above the door showed 9.15. The day had hardly begun and Harry already felt drained of energy, like an old, dying lion who hung back from the pack when once he could have challenged the leader. Not that he had ever nurtured ambitions of leading the pack, but things had taken a nosedive anyway. All he could do was lie low and hope that someone would throw him a bone.
And someone had thrown him a bone. A big one.
The muffled acoustics in the small interview rooms gave Harry the feeling he was talking into a duvet.
‘I import hearing aids,’ the short, stout man said, running his hand down his silk tie. A discreet gold tiepin held his tie in place against the white shirt.
‘Hearing aids?’ Harry repeated, looking down at the interview sheet which Tom Waaler had given him. In the box for his name the man had written Andre Clausen and under profession, Private Businessman.
‘Have you got hearing problems?’ Clausen asked. Harry couldn’t decide whether this sarcasm was being directed towards himself or whether Clausen was being ironic.
‘Mm. So you were at Halle, Thune and Wetterlid’s to talk about hearing aids?’
