‘This is the eldest brother, Mats. According to his boss, he’s been in Mallorca for the past two weeks. But that’s not true. The charter company says that Mats never showed up at the airport to check in for his flight. Instead, he’s been shuttling back and forth between Stockholm and Gotland. I think this is the man we’re after.’
The news caused a ripple to pass through the room.
‘So it’s the half-brother. The one who grew up with foster families,’ said Smittenberg with a sigh.
Everyone was staring at the photo on the screen. Knutas told them what Mikaela Hammar had said about Mats Andersson and then added more details.
‘He’s forty-one years old and lives in Södermalm. Veronika gave birth to him at Visby Hospital in 1966. She was only fifteen at the time. Nobody knows who the father is. The birth records list the father as “unknown”. Mats is a bachelor with no children. He works at a silver-plating company in the industrial district of Länne in Haninge.’
‘A silver-plating company? What the hell is that?’ asked Wittberg.
‘They apply the finished surface to metal. And according to the CEO, there’s a specific substance that’s needed for the manufacturing process. Potassium cyanide.’
Knutas paused for effect as his colleagues digested this piece of information.
‘The man has quite a troubled past. He grew up with a whole series of foster families, and has been convicted of assault on numerous occasions. He has also been arrested for receiving stolen goods and for petty theft. But he’s had a clean record for the past ten years. Seems he’s been behaving himself.’
Sohlman looked at his watch.
‘It’s seven fifteen. The murder was committed around three thirty. So where is Mats now?’
‘He hasn’t left Visby, at least not using his own name,’ said Knutas. ‘The boat for Nynäshamn left Visby at four forty-five, and he could have easily made it on board. It arrives in Nynäs at eight o’clock, and we’ve asked to have all the passengers remain on board until the police search the whole ship. It’s going to cause a big ruckus, but that can’t be helped.’
Memories of the previous year’s hunt for a murderer flickered through Knutas’s mind. On that occasion the police had also been forced to delay a Gotland ferryboat, but their search had proved fruitless, even though the killer was actually on board. Knutas cast a surreptitious glance at Karin. A searing pain passed through his body as he remembered what a dilemma he was in. Was he really going to keep her secret?
Then he went on. ‘Our colleagues in Stockholm have been to his flat, but he wasn’t there. They’re also going to see if he might be visiting his brother Simon, since Mats has the most contact with him. And they live just a stone’s throw from each other, on either side of Slussen.
‘The question is: Where has he been staying when he comes to Gotland?’ said Knutas. ‘I’ve asked all the hotels, B and Bs, hostels, cabin rental agencies and campground owners to look through their records. Unfortunately, it’s going to take time before we hear back from all of them.’
‘He has a brother here on Gotland,’ said Jacobsson. ‘Who’s to say he’s not staying with Andreas?’
JOHAN’S MOBILE RANG as he and Pia were on their way to the café where Veronika Hammar was murdered. As soon as Johan took the call, Pia could tell that something was seriously wrong.
The doctor told him that Emma was in intensive care. She had been found at the very café they were on their way to visit. But she was just running some errands, Johan thought in bewilderment.
At that moment they had entered the roundabout at Norrgatt; Pia was driving towards the northern gate in the ring wall.
‘Go to the hospital!’ he shouted, still holding the mobile to his ear. ‘We have to go to the hospital!’
Pia quickly turned the steering wheel the other way, casting a startled look at her colleague.
‘What’s going on?’
‘Emma’s in intensive care. She was at the café when Veronika Hammar was killed, and she tried to save her. Now she’s in a serious condition herself.’ He pounded his fist on the side of the passenger door. ‘Shit, shit, shit.’
Pia brought the car to such an abrupt stop at the hospital entrance that the tyres shrieked against the asphalt. As Johan jumped out of the car, she yelled after him: ‘It’ll be OK. She’ll be fine!’
She could hear how hollow her words sounded.
WHEN THE MEETING of the investigative team was over, Knutas sat down at his desk and punched in the phone number for Simon Hammar in Stockholm. No one answered. The phone rang and rang, echoing in his ear. He sighed and went out to the corridor to get himself a cup of coffee from the vending machine. The whole station was buzzing with activity, and a nationwide alert had been issued for Mats Andersson. Knutas speculated what his motive could be. Was he so eager to kill his mother because she’d abandoned him when he was a newborn? If so, why had he decided to do it now, at the age of forty-one?
