Erik heads for his office in the hospital, thinking about the journey in the ambulance that morning, after he had found Simone on the floor with virtually no pulse. The rapid trip through the bright city, the rush-hour traffic giving way to the blaring siren of the ambulance. Simone’s stomach being pumped, the efficiency of the female doctor, her calm, speedy actions. The oxygen, the dark screen showing the irregular rhythm of the heart.

In the corridor, Erik checks his mobile phone and realizes it is turned off. He stops and listens to all his messages. Yesterday a police officer named Roland Svensson called four times to offer police protection. There is no message from Benjamin or from anyone who had anything to do with his disappearance.

He calls Aida, and feels a chilling wave of panic as her high voice, suffused with fear, tells him she has absolutely no idea where Benjamin might be.

“Could he have gone to that place in Tensta?”

“No,” she replies.

Erik calls David, Benjamin’s oldest friend from childhood. David’s mother answers. When she says she hasn’t seen Benjamin for several days, he simply cuts off the conversation in the middle of her flow of words.

He calls the path lab to check on their analysis, but they can’t tell him anything yet; Simone’s blood samples have only just arrived.

“I’ll hang on,” he says.

He can hear them working, and after a while they report that Simone was injected with “something containing alfentanil.”

“Alfentanil? The anaesthetic?”

“Somebody must have got hold of it, either from a hospital or a veterinary surgery. We don’t use it here much, it’s so bloody addictive. But it looks as if your wife was incredibly lucky.”

“What do you mean?” asks Erik.

“She’s still alive.”

Erik returns to Simone’s room to go through everything one more time but sees that she has fallen asleep. Her lips are cracked and sore after having her stomach pumped.

His phone rings in his pocket, and he moves into the corridor before answering. “Yes?”

“It’s Linnea at reception, Dr. Bark. You’ve got a visitor.”

It takes a few seconds for Erik to realize that the woman means reception here at the hospital, in the neurosurgical unit, and that she is the Linnea who has worked at the reception desk for four years.

“Dr. Bark?” she asks tentatively.

“A visitor? Who is it?”

“Joona Linna,” she replies.

Erik stands in the corridor, waiting for Joona, his mind racing. He thinks about his voicemail messages; Roland Svensson called over and over to offer him police protection. Has somebody threatened me? Erik asks himself; a chill runs through him as he realizes how unusual it is for a detective from the National CID to come and see him in person rather than contacting him by phone.

He wanders into the cafeteria, where a platter of cold cuts and bread has been left for the taking. A feeling of nausea twists and turns inside his body. His hands shake as he pours water into a scratched glass.

Joona has come to tell me they’ve found Benjamin’s body, he thinks. That’s why he’s here in person. He’s going to ask me to sit down; then he’s going to tell me Benjamin is dead.

Terrifying images flash through his mind with increasing speed: Benjamin’s body in a ditch beside the motorway, or in a black rubbish bag in some forest, washed up on a muddy shore.

“Coffee?”

“What?”

“Would you like some coffee?”

A young woman with shining blonde hair is standing next to the coffee machine, holding up a steaming pot. She looks inquiringly at him, and he realizes he holds an empty cup in his hand. As he shakes his head, Joona Linna walks into the room.

“Let’s sit down,” says Joona. He wears a troubled expression.

Erik nods, and they sit down at a table by the wall. Joona fidgets with the salt shaker and whispers something.

“What?” asks Erik.

“We’ve been trying to reach you.”

“I didn’t answer my phone yesterday,” says Erik faintly.

“Erik, I’m sorry to inform you that Josef Ek has run away from the hospital.”

“What?”

“You’re entitled to police protection.”

Erik’s mouth begins to tremble, and his eyes fill with tears. “Was that what you came to tell me? That Josef has run away?”

“Yes.”

Erik is so relieved that he would like to lie down on the floor and simply sleep. He quickly wipes the tears from his eyes. “When did this happen?”

“Last night. He killed a nurse, stole a car, and seriously injured its driver,” Joona says heavily.

Erik nods several times as his thoughts rapidly make new connections. Absolute terror overwhelms the relief of a moment ago. “He came to our house in the middle of the night and took our son,” he says.

“What are you saying?”

“Josef has taken my son, Benjamin.”

“You mean Benjamin was abducted? Did you see it happen?”

“I didn’t, but Simone— ”

“What happened?”

“Simone was injected with a powerful drug,” Erik says slowly. “I just got the results of her blood test; it’s an anaesthetic called alfentanil, used in major surgery.”

“But she’s all right?”

“She will be.”

Joona nods and writes down the name of the drug. “And Simone said she saw Josef take Benjamin?”

“She didn’t see the person’s face.”

“OK.”

“Are you going to find Josef?” asks Erik.

“Trust me, we’ll find him. There’s a national alert out for him. He’s badly injured. He’s going nowhere.”

“But you haven’t got any leads?”

Joona gives him a hard stare. “I don’t think it will be long before we find him.”

“Good.”

“Where were you when he came to your apartment?”

“I was sleeping in the spare room,” explains Erik. “I’d taken a pill, and I didn’t hear a thing.”

“So when he came into the bedroom, he only found Simone.”

“Yes.”

“This doesn’t make sense,” says Joona.

“It’s easy to miss the spare room. It looks more like a closet, hidden when the bathroom door is open. He probably thought I wasn’t home.”

“I don’t mean that,” says Joona. “I mean this doesn’t sound like Josef. He doesn’t give people injections; his behaviour is far more aggressive.”

“Perhaps it just looks aggressive to us,” says Erik.

“What do you mean?”

“Perhaps he knows what he’s doing all the time. I mean, you didn’t find any of his father’s blood on him back at home. That suggests he works systematically, coldly. What if he decided to get his revenge on me by taking Benjamin?”

There is silence. From the corner of his eye, Erik can see the blonde woman by the coffee machine sipping from her cup as she gazes out over the hospital complex.

Joona looks down at the table; then he meets Erik’s eyes and says gently, “I am really very sorry, Erik.”
