to each other, leaning close and conversing in low voices. The police spokesman, Lars Norrby, was missing. He’d taken a two-month leave of absence to sail around the West Indies with his children. While Lars was away, Knutas had to handle the press himself, which he didn’t really mind. Things were actually calmer this way. He and Norrby didn’t always agree about what information should be made public.
Knutas had just sat down in his customary place at the head of the table when Sohlman came in. The crime-scene tech’s face was ashen and he looked as if he hadn’t slept all night.
He sank down on a chair next to Jacobsson, who patted him lightly on the shoulder. Sohlman reached for the thermos of coffee on the table.
‘Good morning,’ Knutas greeted everyone. ‘You all know about what happened. Viktor Algård was found dead yesterday afternoon inside the conference centre. According to the ME’s preliminary examination, Algård died of cyanide poisoning. But he also had a wound on his forehead, and there were bloodstains both on the cocktail table near the bar and on the floor underneath. Marks on the floor indicate that the perpetrator dragged the body into the lift, presumably to hide it. We don’t know yet what caused the wound on the victim’s forehead. The body is being taken on the afternoon ferry to Stockholm and the Forensics division in Solna. We’re hoping that the post-mortem will be done tomorrow. Sohlman, can you describe what we know so far about the injuries and crime scene?’
Knutas nodded to his colleague, who got up to stand next to the screen at the front of the room.
‘First let’s take a look at the victim. Certain circumstances make this a particularly interesting case. You can see that the victim’s skin is bright pink. Livor mortis, which is a light crimson or rose colour, has fully developed. This points to cyanide poisoning, since cyanide obstructs the airways, making it impossible for oxygen to get out of the bloodstream. The victim also smelled strongly of bitter almonds, which is typical of cyanide poisoning.’
‘I don’t know anything about cyanide,’ said Jacobsson, ‘but it must be an extremely unusual method for killing someone. I’ve only heard of it used as a murder weapon in old detective novels.’
‘I know. I’ve never handled a homicide case in which cyanide was used,’ Sohlman agreed. ‘But I’ve actually had a couple of instances of suicide by cyanide. It’s extremely toxic. In this instance we’re probably dealing with potassium cyanide, which is cyanide in crystal form. It dissolves easily in water.’
‘Why did you make that assumption?’
‘Because that’s the easiest form to handle and carry around. It can be kept in small glass vials. Then all you need to do is empty the contents into a glass of water, or some other liquid.’
‘What about alcohol?’ asked Jacobsson.
‘It doesn’t dissolve in alcohol, but the perpetrator could have mixed it in water first, before adding it to a drink. If that’s how the poison was administered to Algård, that is. We don’t know for sure. But it’s not the sort of substance that anyone would drink voluntarily. The perp must be at least somewhat familiar with cyanide. Handling it can be quite risky. For one thing, it’s fatal if inhaled. Hydrogen cyanide was the gas that the Germans used to murder the Jews in the concentration camps in the Second World War. As I said, it can knock out your respiratory system in a matter of minutes.’
‘How does it work?’ asked Knutas.
‘The cyanide instantly blocks the airways. You could say that the cells are suffocated, and the victim will have trouble breathing immediately after ingesting the poison. I presume it’s sometimes used as a method of committing suicide because it’s such a lethal substance. If you take a sufficient amount of cyanide, you will definitely die. And it happens so fast, taking anywhere from thirty seconds to a few minutes,
