hysteria?"

"Sometimes it's like the whole country is against us."

"Did he crack the code? Why isn't this a question of encryption?"

"You really do make it sound like a cloak-and-dagger affair. No, he didn't crack any code. Not really. He went about it differently."

"What did he do?"

"He set up a research project that no-one had authorised. He forged signatures, including mine. He pretended the company was researching the genetic transmission of an oncogenic disease found in several families in Iceland. He tricked the data privacy committee – a kind of monitoring agency for the database. He tricked the scientific ethics commit-tee. He tricked us all here."

She stopped talking for a moment and looked at her watch. She stood up and went over to her desk and called her secretary to postpone a meeting for ten minutes then sat back down with Erlendur.

"That's been the dynamics up to now," she said.

"Dynamics?" Erlendur said.

Karítas looked at him thoughtfully. The mobile phone in Erlendur's pocket started ringing. He excused himself and answered. It was Sigurdur Óli.

"Forensics have been through Einar's flat on Storagerdi," he said. "I called them and they haven't really found anything except that Einar got himself a fire-arms licence two years ago or so."

"A fire-arms licence?" Erlendur repeated.

"It's on our register. But that's not all. He owns a shotgun and we found the sawn-off barrel under his bed."

"The barrel?"

"He'd sawn off the barrel. They do that some-times. Makes it easier to shoot themselves."

"Do you think he could be dangerous?"

"When we find him," Sigurdur Óli said, "we need to approach him carefully. We can't predict what he'll do with a gun."

"He can hardly intend to kill anyone with it," said Erlendur, who had stood up and turned his back on Karítas for some kind of privacy.

"Why not?"

"He would have already used it," Erlendur said in a low voice. "On Holberg. Don't you think?"

"I honestly don't know."

"See you," Erlendur said, switched off the phone and repeated his apologies before he sat down again.

"That's been the process up to now," Karítas resumed where she'd left off. "We apply to these authorities for permission to conduct a research project, like in Einar's case, the study of the genetic transmission of a specific disease. We're given an encrypted list of names of people who suffer from the disease or are conceivable carriers and compare it to the encrypted genealogy database. Then we can produce a kind of encrypted family tree."

"Like a message tree," Erlendur said.

"What?"

"No, do go on."

"The data privacy committee decodes the list with the names of the people we want to study, what we call a sample group, both patients and relatives, and it produces a list of participants with their ID numbers. Do you follow?"

"And that's how Einar obtained the names and ID numbers of anyone who had the disease in their family."

She nodded.

"Does this all go through the data privacy committee?"

"I don't know how deeply you want to go into this. We're working with doctors and various establishments. They submit the names of patients to the privacy committee, which encrypts the names and ID numbers and sends them here to the Genetic Research Centre. We have a dedicated genealogical tracer program which arranges patients into cluster groups on the basis of their relationship to one another. Using this program we can select the patients who provide the best statistical information for searching for specific genetic disorders. Then we ask individuals from this group to take part in the study. Genealogy is valuable for seeing whether a genetic disease is involved, selecting a good sample, and it's a powerful tool in the search for genetic disorders."

"All that Einar needed to do was to pretend to create a sample and have the names decoded, all with the help of the data privacy committee."

"He lied and tricked everyone and he got away with it."

"I can understand how this could be embarrassing for you."

"Einar is among our top management here and one of our most capable scientists. A fine man. Why did he do it?" the director asked.

"He lost his daughter," Erlendur said. "Didn't you know about that?"

"No," she said, staring at him.

"How long's he been working here?"

"Two years."

"It was some time before then."

"How did he lose his daughter?"

"She had a genetically transmitted neural disease. He was the carrier but didn't know about the disease in his family."

"A question of paternity?"

Erlendur didn't answer her. Felt he'd said enough.

"That's one of the problems with this kind of genealogy database. Diseases tend to jump out of the family tree
