you let me have that back?"
"Where is she?"
"Do I get it back if I tell you?"
"If you're not lying. Where is she?"
"There was a girl with her."
"Who? What's her name?"
"I know where she lives."
Erlendur took a step closer.
"You'll get it all back," he said. "Who was this girl?"
"Ragga. She lives just round the corner. On Tryggva-gata. At the top of the big building overlooking the dock." Alli hesitantly stretched out his hand. "Okay? You promised. Give it back to me. You promised."
"There's no way I could give it back to you, you idiot," Erlendur said. "If I had the time I'd take you down to the station and throw you in a cell. So you've come off the better for it."
"No, they'll kill me! Don't! Let me have it, please. Let me have it!"
Ignoring him, Erlendur left Alli snivelling up against the building, where he cursed himself and banged his head against the wall in feeble rage. Erlendur could hear the curses a long way off, but to his surprise Alli directed them not at him, but at himself.
"Fucking jerk, you're a fucking jerk . . ."
He looked round and saw Alli slapping himself in the face.
A little boy, possibly four years old, wearing pyjama bottoms, barefoot, his hair filthy, opened the door and looked up at Erlendur, who stooped down to him. When Erlendur put out his hand to stroke the boy's cheek he jerked his head back. Erlendur asked if his mother was home, but the boy just gave him a questioning look and made no reply.
"Is Eva Lind with you, sonny?" he asked.
Erlendur had the feeling time was running out. It was two hours since Eva Lind had phoned. He tried to dispel the thought that he was already too late to help her. Tried to imagine what kind of quandary she was in, but soon stopped torturing himself that way and concentrated on finding her. Now he knew who she was with when she left Alli that evening. He could sense he was getting closer to her.
Without answering, the boy darted back into the flat and disappeared. Erlendur followed, but could not see where he went. The flat was pitch dark and Erlendur fumbled to find a light switch on the walls. After trying several that did not work, he groped his way into a small room. At last a solitary light bulb, hanging from the ceiling, flickered on. There was nothing on the floor, only cold concrete. Dirty mattresses were spread all around the flat and on one of them lay a girl, slightly younger than Eva Lind, in tattered jeans and a red T-shirt. A metal box containing two hypodermic needles was open beside her. A thin plastic tube lay curled on the floor. Two men were sleeping on mattresses on either side of her.
Erlendur knelt down by the girl and prodded her, but got no response. He lifted her head, sat her up and patted her cheek. She mumbled. He stood up, lifted her to her feet and tried to make her walk around, and soon she seemed to come to her senses. She opened her eyes. Erlendur noticed a kitchen chair in the darkness and made her sit down. She looked at him and her head slumped to her chest. He slapped her face lightly and she came to again.
"Where's Eva Lind?" Erlendur asked.
"Eva," the girl mumbled.
"You were with her today. Where did she go?"
"Eva . . ."
Her head slumped again. Erlendur saw the little boy standing in the doorway. He was holding a doll in one hand and in the other he had an empty feeding bottle which he held out towards Erlendur. Then he put the bottle in his mouth and Erlendur heard him sucking in the air. He watched the boy and gnashed his teeth before taking out his mobile to call for help.
A doctor arrived with the ambulance, as Erlendur had insisted.
"I have to ask you to give her a shot," Erlendur said.
"A shot?" said the doctor.
"I think it's heroin. Have you got any naloxone or narcanti? In your bag?"
"Yes, I . . ."
"I have to talk to her. Immediately. My daughter's in danger. This girl knows where she is."
The doctor looked at the girl, then back at Erlendur. He nodded.
Erlendur had laid the girl back on the mattress and it took her a
