Covert intelligence sources and their confidentiality protections

Covert intelligence sources and their confidentiality protections are a recurring institutional tension in the novel: secrecy can keep an infiltrator and the people connected to him alive, yet it can also prevent investigators from solving a murder or holding officials to account. The protection is not merely a promise to conceal a name. It determines who may know what, when a source can be identified, and which version of events enters an official investigation.

The rationale for concealment

The police handler’s refusal to identify an informer is grounded in a practical danger: unnecessary disclosure can expose a source. When Ewert Grens asks about an informer, he is told that the identity cannot yet be revealed and that withholding it is part of the work of protecting covert human intelligence sources. The novel presents this as an established practice, not an improvised excuse. Its necessity has grown as the number of sources has increased.

That rationale carries a cost. Grens understands the need for protection but dislikes the secrecy surrounding informers and their operations. The novel describes a police service in which individual officers can call themselves handlers and establish their own CHIS contacts. As those relationships multiply, guarding identities can become more important than giving other officers accurate information. Confidentiality, intended to prevent harm, can thus interfere with the police’s ability to coordinate their work.

The problem is not simply that one officer knows a secret and another does not. A source’s identity may be connected to other infiltrators, recommendations, and operations. A disclosure that seems necessary to one investigation can therefore put people beyond that investigation at risk. The protections are designed around this wider network, even when the immediate cost falls on an investigator seeking evidence.

The murder investigation and the withheld identity

The conflict becomes concrete when Ewert Grens pursues the identity of an infiltrator called Carsten. Fingerprints provide a lead, but Jacob Andersen, acting as the source’s handler, refuses to give Grens a personal identity, address, or other identifying details. Andersen explains that Carsten was one of several infiltrators involved in the operation and that disclosure could therefore expose more than one person. Grens, leading a murder investigation, sees the refusal from the other side: the Danish police have operated on Swedish territory without informing the Swedish police, and after a murder, continue to withhold information from the officers investigating it.

The two positions are both tied to institutional duty, but they are not compatible in the moment. Grens insists that his investigation requires information; Andersen treats disclosure as a threat to the wider operation. Grens warns that if the case remains unsolved for another twenty-four hours, he will require a meeting and an exchange of information. His anger makes visible what the confidentiality rule suppresses: the investigation is proceeding with a deliberately incomplete account of the events surrounding the murder.

Andersen eventually makes the conditions of disclosure explicit. He had withheld information over the telephone because he first needed to establish who Grens was and whether he could be trusted. The discussion, he insists, must remain within the room. This is a controlled release rather than a full opening of the files: the information is shared only after a trust assessment and under a boundary intended to prevent its spread beyond the meeting.

Parallel records and the decision to continue Paula’s operation

The same logic shapes the handling of Paula. A five-sheet secret report about events at Västmannagatan 79 reaches Fredrik Göransson, while another account of the same murder records the progress of Grens, Sven Sundkvist, and Mariana Hermansson’s official investigation. The separate documents do not merely offer different emphases. The official account contains only what the officers controlling the information allow it to contain, while the secret report records what the undercover operation has learned.

Erik Wilson asks that any part Paula may have played in the murder remain within the secret report. He argues that revealing the source could endanger an operation close to a breakthrough against a developing mafia branch. He also points to the history of the source’s work: Wilson says he has received reports on the infiltrator for nine years and that the source has never failed. Göransson, however, refuses to promise protection for a high-risk source when the report implicates Paula in murder. The disagreement is not over whether the source matters, but over whether the value of the operation can justify continuing to shield him under such circumstances.

Wilson presses for the operation to continue for at least two more months. He argues that losing this opportunity would mean losing a chance to disrupt the criminal organization before it is fully established. Göransson calls a meeting at Rosenbad rather than resolving the question privately. The decision illustrates how confidentiality becomes a question of institutional authorization: a handler can argue for a source, but continued protection depends on senior officials accepting the risk and the operational value.

Confidentiality inside the prison operation

Piet Hoffmann’s entry into Aspsås Prison shows how covert work depends on managing both official and criminal identities. Before arriving, he has mapped the buildings from the church tower and, with Erik Wilson’s help while on remand, learned about prisoners and staff in Block G. After his first entry into the prison, he is processed, given clothes, and placed in conditions of isolation. Ten days later, he has spent twenty-three hours of each day alone in a five-square-metre cell. The source’s preparation is extensive, but it does not remove the prison’s control over his time, movement, and access to other people.

When Hoffmann is brought into the unit, he makes his presence conspicuous rather than waiting to be accepted quietly. He sits where the prisoners will see him and chooses a marked seat and cards without asking permission. Stefan Lygas and Karol Tomasz Penderecki have already prepared the ground by discussing his arrival, his alleged background, and his status. They have also obtained copies of records and a recent judgment through Stefan’s lawyer. Those materials help make a criminal identity legible to the other prisoners, while Hoffmann’s conduct performs the confidence expected of that identity.

The concealment is therefore not only a matter of keeping the police informant’s name from investigators. It also requires restricting knowledge of his role within the prison, while supplying enough corroborating detail for his assumed identity to withstand scrutiny. Yet the arrangement is precarious: Hoffmann later concludes that one of the people serving as his protection and route of escape has exposed him. The text does not identify which person betrayed him. That uncertainty leaves the breach itself, rather than a named culprit, as the decisive fact.

Protection, exposure, and the cost of secrecy

The novel treats confidentiality as a form of protection with no guarantee of safety. At its best, limited disclosure keeps a network from being exposed through a single source’s identity. At its worst, the same limits divide agencies, produce parallel records, and prevent investigators from seeing the full connection between a murder and an undercover operation. Even an authorized handler’s judgment is not enough to settle the conflict: Wilson’s confidence in Paula meets Göransson’s refusal to guarantee protection to a source implicated in a killing.

The prison episodes extend this tension from official procedure to everyday survival. Hoffmann’s cover relies on documents, collaborators, knowledge of the prison, and a carefully staged reputation; it can be undone by someone within the circle on which that cover depends. Confidentiality may conceal a source from one audience while leaving him exposed to another. The novel’s central irony is that the systems designed to protect informants can preserve secrecy without ensuring that anyone remains able—or willing—to protect the person behind it.
