Kronoberg Police HQ is the principal workplace through which Jeanette Kihlberg’s investigation takes shape: a place for assessing evidence, testing connections between cases, and confronting tensions within the police. The scenes set there move between practical casework and the less formal relationships that influence it, making the headquarters a point where private histories and institutional power repeatedly meet.

Investigative work and the widening case

At Kronoberg Police HQ, information that might otherwise remain scattered begins to form a wider pattern. In one discussion, Jens Hurtig asks about Sihtunum i Diasporan. Jeanette explains that the name combines runic Swedish for Sigtuna with classical Greek for living in exile, and describes a foundation whose members have a connection to the Sigtuna boarding school. The exchange turns an unfamiliar name into a possible route into the school’s history and its former pupils.

Jeanette later asks Hurtig to obtain the school’s registers and, if possible, yearbooks. She identifies Fredrika Grünewald, Charlotte Silfverberg, and their friend Henrietta Nordlund as names of interest, while singling out the missing Victoria Bergman as the person whose appearance she most wants to establish. The records are not merely background: they could help the investigators place people in relation to one another and to the institution.

The foundation becomes more significant when Jeanette connects Bengt Bergman, Viggo Dürer, and Karl Lundström to it, along with Per-Ola Silfverberg. She adds that the former commissioner, Gert Berglind, knew Lundström through a foundation. The resulting picture is still a working hypothesis, not proof of shared wrongdoing, but it shifts the inquiry from separate suspects toward overlapping social and institutional ties. At headquarters, the foundation functions as a lead whose importance depends on verifying who knew whom and through what channel.

Evidence, uncertainty, and casework

The headquarters scenes also show how the investigation proceeds through incomplete evidence. In the case of Fredrika Grünewald, Jeanette reasons that the killer was probably someone she knew: Grünewald’s home was orderly, there were no signs that she had tried to defend herself, and the available circumstances suggested that she had let the person in before being overpowered. Jeanette treats this as the hypothesis the team should work from, not as an established identification of the killer.

A later scene finds Jeanette at her desk with photographs spread before her, studying Hannah Östlund’s image. Hannah has become a principal suspect in a series of murders, though she was a stranger to Jeanette only a short time earlier. The photographs register a shift in the inquiry: people once distant from the case have become central to it, and appearances can no longer be taken as a reliable guide to their roles.

Jeanette’s requests about Viggo Dürer show another way the team follows a lead after a suspect’s death. She wants his past investigated because it may contain evidence pointing toward the murderer. She is already aware that someone paid half a million kronor into Annette Lundström’s bank account and suspects the payment could have been a bribe, although its source has not been traced. Sofia Zetterlund has told her that Ulrika Wendin had substantial cash and implied that Dürer might be behind it. A letter Karl Lundström wrote to his daughter Linnea and drawings Linnea made as a child also raise suspicions about Dürer. Each item is suggestive rather than conclusive; their force lies in how they converge on questions the investigators can pursue.

Institutional relationships and friction

Kronoberg Police HQ is also a setting for the changing relationship between Jeanette and the institution she works within. Under Gert Berglind, she reflects, police relationships had seemed simpler: people knew one another, and socializing with the right people could advance a career. Lundström and Silfverberg had been close friends of both Berglind and Dürer. Since Dennis Billing took over, cooperation with the police has become less smooth. The contrast makes the investigation’s social connections more than a list of names: old friendships and professional influence form part of the environment the team must navigate.

That institutional pressure coexists with ordinary collegial concern. During a discussion of the case, Hurtig tells Jeanette that his father’s condition has worsened after an accident with a saw. The hospital has accepted liability for giving him the wrong medication, but he has developed gangrene and will need to have his fingers amputated; he has also suffered a head injury in a separate accident. Jeanette recognizes the gravity of the news even as she keeps the meeting moving because there is work to do. The exchange gives the office a human dimension without displacing the investigation: the people pursuing the case carry urgent private concerns into their working conversations.

A threshold between work and private life

The headquarters is repeatedly framed as a place Jeanette leaves without leaving the investigation behind. After work, she takes the lift down to the garage beneath police headquarters and drives home, still turning over the coincidences connecting two girls, their fathers, and the Sigtuna school. The journey marks a physical departure from the office, but her thinking continues to sort the case’s relationships: Madeleine Silfverberg and Linnea Lundström; their fathers, Per-Ola Silfverberg and Karl Lundström; and the connection between Charlotte Silfverberg and the murdered Fredrika Grünewald.

Another scene places the headquarters against a broader portrait of Stockholm’s winter. The city is described as dark for much of the day, with people withdrawing into private worlds and avoiding contact with those around them. This urban atmosphere surrounds the police work without providing an explanation for the crimes; instead, it gives the setting a sense of isolation that contrasts with the investigators’ effort to make connections. At the office, a package waits on Jeanette’s desk after she has driven Johan to school, a small reminder that the workday brings new matters before the previous ones have settled.

Across these episodes, Kronoberg Police HQ is less a building described for its architecture than a recurring site of interpretation and transition. Here, a foundation links possible suspects to a school and to former police leadership; documents, photographs, and money suggest lines of inquiry but leave important questions open; and colleagues’ personal lives intrude on professional routines. The movement between desk, meeting, garage, and home reinforces the investigation’s central difficulty: Jeanette can leave the headquarters, but the connections she has noticed continue to follow her.
