ican president."
"First name?"
"Fredrik. I saw him four or five times."
"Others?"
"Hans von Rottinger. I knew him through my mother."
"Your mother?"
"Yes, my mother knew the von Rottinger family. Hans von Rottinger was always a pleasant guy. Before he turned up out of the blue at a meeting with Gullberg, I had no idea that he worked for Sapo."
"He didn't," Blomkvist said.
Janeryd turned pale.
"He worked for something called the Section for Special Analysis," Blomkvist said. "What were you told about that group?"
"Nothing. I mean, just that they were the ones who took care of the defector."
"Right. But isn't it strange that they don't appear anywhere in Sapo's organizational chart?"
"That's ridiculous."
"It is, isn't it? So how did they set up the meetings? Did they call you, or did you call them?"
"Neither. The time and place for each meeting was set at the preceding one."
"What happened if you needed to get in contact with them? For instance, to change the time of a meeting or something like that?"
"I had a number to call."
"What was the number?"
"I couldn't possibly remember."
"Who answered if you called the number?"
"I don't know. I never used it."
"Next question. Who did you hand everything over to?"
"How do you mean?"
"When Falldin's term came to an end. Who took your place?"
"I don't know."
"Did you write a report?"
"No. Everything was classified. I couldn't even take notes."
"And you never briefed your successor?"
"No."
"So what happened?"
"Well . . . Falldin left office, and Ola Ullsten came in. I was told that we would have to wait until after the next election. Then Falldin was re-elected and our meetings were resumed. Then came the election in 1985. The Social Democrats won, and I assume that Palme appointed somebody to take over from me. I transferred to the foreign ministry and became a diplomat. I was posted to Egypt, and then to India."
Blomkvist went on asking questions for another few minutes, but he was sure that he already had everything Janeryd could tell him. Three names.
Fredrik Clinton.
Hans von Rottinger.
And Evert Gullberg--the man who had shot Zalachenko.
The Zalachenko club.
He thanked Janeryd for the meeting and walked the short distance along Lange Voorhout to Hotel Des Indes, from which he took a taxi to Centraal. It was not until he was in the taxi that he reached into his jacket pocket and stopped the tape recorder.
Berger looked up and scanned the half-empty newsroom beyond the glass cage. Holm was off that day. She saw no-one who showed any interest in her, either openly or covertly. Nor did she have reason to think that anyone on the editorial staff wished her ill.
The email had arrived a minute before. The sender was . Why Aftonbladet? The address was another fake.
Today's message contained a JPEG, which she opened in Photoshop.
The image was pornographic: a naked woman with exceptionally large breasts, a dog collar around her neck. She was on all fours and being mounted from the rear.
The woman's face had been replaced with Berger's. It was not a skilled collage, but probably that was not the point. The picture was from her old byline at Millennium and could be downloaded off the Net.
At the bottom of the picture was one word, written with the spray function in Photoshop.
Whore.
This was the ninth anonymous message she had received containing the word whore, sent apparently by someone at a well-known media outlet in Sweden. She had a cyber-stalker on her hands.
The telephone tapping was a more difficult task than the computer monitoring. Trinity had no trouble locating the cable to Prosecutor Ekstrom's home phone. The problem was that Ekstrom seldom or never used it for work-related calls. Trinity did not even consider trying to bug Ekstrom's work phone at police HQ on Kungsholmen. That would have required extensive access to the Swedish cable network, which he did not have.
But Trinity and Bob the Dog devoted the best part of a week to identifying and separating out Ekstrom's mobile from the background noise of about 200,000 other mobiles within half a mile of police headquarters.
They used a technique called Random Frequency Tracking System. The technique was not uncommon. It had been developed by the U.S. National Security Agency, and was built into an unknown number of satellites that performed pinpoint monitoring of capitals around the world, as well as flashpoints of special interest.
The NSA had enormous resources and used a vast network in order to capture a large number of mobile conversations in a certain region simultaneously. Each individual call was separated and processed digitally by computers programmed to react to certain words, such as terrorist or Kalashnikov. If such a word occurred, the computer automatically sent an alarm, which meant that some operator would go in manually and listen to the conversation to decide whether it was of interest or not.
It was a more complex problem to identify a specific mobile. Each mobile has its own unique signature--a fingerprint--in the form of the phone number. With exceptionally sensitive equipment the NSA could focus on a specific area to separate out and monitor mobile calls. The technique was simple but not 100 percent effective. Outgoing calls were particularly hard to identify. Incoming calls were simpler because they were preceded by the fingerprint that would enable the phone in question to receive the signal.
The difference between Trinity's and the NSA's attempting to eavesdrop could be measured in economic terms. The NSA had an annual budget of several billion U.S. dollars, close to 12,000 full-time agents, and access to cutting-edge technology in IT and telecommunications. Trinity had a van with sixty pounds of electronic equipment, much of which was homemade stuff that Bob the Dog had set up. Through its global satellite monitoring, the NSA could train highly sensitive antennae on a specific building anywhere in the world. Trinity had an antenna constructed by Bob the Dog which had an effective range of about 500 yards.
The relatively limited technology to which Trinity had access meant that he had to park his van on Bergsgatan or one of the nearby streets and laboriously calibrate the equipment until he had identified the fingerprint that represented Ekstrom's mobile number. Since he did not know Swedish, he had to relay the conversations via another mobile to Plague, who did the actual eavesdropping.
For five days, Plague, who was looking more and more hollow-eyed, listened in vain to a vast number of calls to and from police headquarters and the surrounding buildings. He heard fragments of ongoing investigations, uncovered planned lovers' trysts, and taped hours and hours of conversations of no interest whatsoever. Late on the evening of the fifth day, Trinity sent a signal which a digital display instantly identified as Ekstrom's mobile number. Plague locked the parabolic antenna on to the exact frequency.
The technology of RFTS worked primarily on incoming calls to Ekstrom. Trinity's parabolic antenna captured the search for Ekstrom's mobile number as it was sent through the ether.
Because Trinity could record the calls from Ekstrom, he also got voice-prints that Plague could process.
Plague ran Ekstrom's digitized voice through a programme called VPRS, Voiceprint Recognition System. He specified a dozen commonly occurring words, such as OK or Salander. When he had five separate examples of a word, he charted it with respect to the time it took to speak the word, what tone of voice and frequency range it had, whether the end of the word went up or down, and a dozen other markers. The result was a graph. In this way Plague could also monitor outgoing calls from Ekstrom. His parabolic antenna would be permanently listening out for a call containing Ekstrom's characteristic graph curve for one of a dozen commonly occurring words. The technology was not perfect, but roug
hly half of all the calls that Ekstrom made on his mobile from anywhere near police headquarters were monitored and recorded.
The system had an obvious weakness. As soon as Ekstrom left police headquarters, it was no longer possible to monitor his mobile, unless Trinity knew where he was and could park his van in the immediate vicinity.
With the authorization from the highest level, Edklinth had been able to set up a legitimate operations department. He picked four colleagues, purposely selecting younger talent who had experience on the regular police force and had been only recently recruited to SIS. Two had a background in the fraud division, one had been with the financial police, and one was from the violent crimes division. They were summoned to Edklinth's office and told of their assignment as well as the need for absolute secrecy. He made plain that the investigation was being carried out at the express order of the prime minister. Inspector Figuerola was named as their chief, and she directed the investigation with a force that matched her physical appearance.
But the investigation proceeded slowly. This was largely due to the fact that no-one was quite sure who or what should be investigated. On more than one occasion Edklinth and Figuerola considered bringing Martensson in for questioning. But they decided to wait. Arresting him would reveal the existence of the investigation.
Finally, on Tuesday, eleven days after the meeting with the prime minister, Figuerola came to Edklinth's office.
"I think we've got something."
"Sit down."
"Evert Gullberg. One of our investigators had a talk with Marcus Erlander, who's leading the investigation into Zalachenko's murder. According to Erlander, SIS contacted the Goteborg police just two hours after the murder and gave them information about Gullberg's threatening letters."
"That was fast."
"A little too fast. SIS faxed nine letters that Gullberg had supposedly written. There's just one problem."
"What's that?"
"Two of the letters were sent to the justice department--to the minister of justice and to the deputy minister."
"I know that."
"Yes, but the letter to the deputy minister wasn't logged in at the department until the following day. It arrived with a later delivery."
Edklinth stared at Figuerola. He felt very afraid that his suspicions were going to turn out to be justified. Figuerola went implacably on.
"So we have SIS sending a fax of a threatening letter that hadn't yet reached its addressee."
