Mads looked at his father, irresolute, and on receiving a faint nod, answered: 'I can't bear to be there now. It's so . . . empty. I'll sleep at home tonight.'
'With us,' the father added by way of explanation and sent him a look that Harry thought should have been sympathy. But it resembled contempt.
They sat down and father and son pushed their business cards across the table to Harry and Halvorsen. Halvorsen responded with two of his own. Gilstrup senior looked at Harry in anticipation.
'Mine haven't been printed yet,' Harry said. Which was true, as far as it went, and always had been. 'But Halvorsen and I work as a team, so all you have to do is ring him.'
Halvorsen cleared his throat. 'We have a few questions.'
Halvorsen's questions sought to establish Ragnhild's movements earlier that day, what she was doing in Jon Karlsen's flat and possible enemies. Each one was met with a shake of the head.
Harry searched for milk for his coffee. He had started taking it. Probably a sign that he was getting old. Some weeks ago he had put on the Beatles' indisputable masterpiece Sergeant Pepper's Lonely Hearts' Club Band and was disappointed. It had got old, too.
Halvorsen was reading questions from his notepad and jotting down notes without making eye contact. He asked Mads Gilstrup to account for where he had been between nine and ten o'clock this morning, which was the doctor's estimate of the time of death.
'He was here,' Albert Gilstrup said. 'We've been working here all day, both of us. We're trying to turn around the firm.' He addressed Harry. 'We expected you to ask that question. I've read that the husband is always the first person the police suspect in murder inquiries.'
'With good reason,' Harry said. 'From a statistical point of view.'
'Fine,' Albert Gilstrup nodded. 'But this isn't statistics, my dear man. This is reality.'
Harry met Albert Gilstrup's flashing blue eyes. Halvorsen glanced across at Harry as though in dread of something.
'So let's stick to reality,' Harry said. 'And shake our heads less and say more. Mads?'
Mads Gilstrup's head shot up as if he had dozed off. Harry waited until they had eye contact. 'What did you know about Jon Karlsen and your wife?'
'Stop!' Albert's wooden-doll mouth snapped. 'That kind of impudence may be acceptable with the clientele that you deal with on a day-to-day basis, but not here.'
Harry sighed. 'If it is your wish, your father may stay here, Mads. However, if I have to, I will throw him out.'
Albert Gilstrup laughed. It was the seasoned victor's laugh from someone who has at last found a worthy opponent. 'Tell me, Inspector, am I going to be obliged to ring my friend the Chief Superintendent and tell him how his men treat someone who has just lost his wife?'
Harry was about to answer, but was interrupted by Mads who raised his hand in a slow, strangely graceful movement. 'We have to find him, Father. We have to help each other.'
They waited, but Mads's gaze had returned to the glass wall and said nothing further.
'All right,' Albert said in English with pukka pronunciation. 'We'll talk on one condition: that we do this face to face, Hole. Your assistant can wait outside.'
'We don't work like that,' Harry said.
'We're trying to cooperate here, Hole, but this demand is not up for discussion. The alternative is to talk to us through our solicitor. Have you understood?'
Harry waited for the anger to rise. And when it still didn't come, he was no longer in any doubt: he was indeed getting old. He nodded to Halvorsen, who looked surprised but got to his feet. Albert Gilstrup waited until the officer had closed the door behind him.
'Yes, we have met Jon Karlsen. Mads, Ragnhild and I met him in his role as financial adviser for the Salvation Army. We made him an offer that would have been very advantageous and he rejected it. A person of high morals and integrity without any doubt. But, of course, he might have been courting Ragnhild anyway; he wouldn't have been the first. I am aware extramarital affairs are not front-page news any more. What makes your intimations impossible, however, is Ragnhild herself. Believe me, I have known the woman for a long time. She is not only a much-loved member of the family; she is also a person with character.'
'And if I tell you she had keys to Jon Karlsen's flat?'
'I don't want to hear any more about the case!' Albert snapped.
Harry glanced at the glass wall and caught the reflection of Mads Gilstrup's face as his father continued.
'Let me get to the point of why we want a face-to-face meeting with you, Hole. You're leading the investigation, and we thought of offering a prize if you catch the person guilty of the murder of Ragnhild. To be precise, two hundred thousand kroner. Absolute discretion.'
'I beg your pardon?' Harry said.
'All right,' Gilstrup said. 'The sum can be discussed. The vital thing for us is that this case is given top priority by the police.'
