Sonja Hökberg’s death at the Ystad power substation causes a regional blackout and exposes how one lethal failure at a central junction can disrupt ordinary life across Skåne. What first appears to be a body found during an electricity emergency becomes a murder investigation: Hökberg has been killed before her body is placed among the high-voltage equipment, though the reason for that act remains unresolved.

The outage and the emergency response

On the evening of October 8, the power fails across a large part of Skåne. In Ystad, the outage reaches Kurt Wallander at home; he initially wonders whether a fuse has blown, then sees that the street lamps are dark as well. At Sydkraft’s main office, Rune Ågren calls the on-duty area officer, Olle Andersson, with the scale of the emergency: about 25 per cent of Skåne is without electricity. The Ystad power substation is a central connection in the network, making a fault there capable of affecting a much wider area.

Andersson reaches the substation in nineteen minutes. Its gates have been broken open, but there is no car or other person in sight. He carries keys for the gates and the transformer building, and uses a torch as he approaches the structure. The steel door is ajar, apparently without having been forced. A strong, unfamiliar smell leads him to look inside. He finds a burned body among the electrical equipment and reports that a person has short-circuited the region. The failure is no longer simply a technical problem: the body is both the cause of the power cut and evidence of a death.

The police are notified shortly after midnight. Although ill, Wallander insists on going to the scene and Martinsson collects him. They drive through dark, rain-soaked Ystad to the substation, where Hansson is waiting. Wallander enters the transformer building with Martinsson’s torch and sees the blackened body trapped among lines, switches, and circuit breakers. He asks for Nyberg and forensic support, and for a generator so the team can work with adequate light. Rain and wind make the investigation difficult; the electrical equipment must be understood as both the scene of a death and part of a system needed to restore power.

From apparent accident to murder

At first, the circumstances leave several explanations open. A suicide could account for a person entering the station, but Wallander notices a crucial mismatch: the outer gates were forced, while the reinforced transformer-building door does not appear to have been. Its locks require keys. That distinction makes the scene difficult to reconcile with a lone intruder and raises the possibility that someone used access to the building before placing the victim in the electrical equipment. Wallander also considers whether the body was already dead when it reached the power lines, a question the initial examination cannot settle.

The outage’s public scale becomes clearer as Wallander listens to the radio from a police car. Darkness stretches from Trelleborg to Kristianstad; hospitals are relying on emergency generators, while a Sydkraft executive expects power to return in most places within half an hour. Wallander doubts that the affected substation can be restored so quickly. He informs Lisa Holgersson that the utility emergency now involves a police investigation. At that stage, he cannot say whether the death was suicide, sabotage, or another kind of crime.

A pathologist’s first important finding changes the identification of the victim. The body is a woman, not the man Wallander had assumed he would find. A technician searching near the fence discovers a handbag. Wallander recognizes its oak-leaf clasp from the interrogation room and identifies it as Sonja Hökberg’s. The discovery connects the body to a woman who had escaped from the police station roughly thirteen hours earlier, making the question of how she reached the substation central to the case.

The investigation later establishes that Hökberg had a fracture at the back of her skull. The pathologist considered it unlikely to have been self-inflicted and believed she may have been unconscious when she encountered the power lines. Wallander treats this preliminary finding as confirmation that she was murdered: the electrical current caused the blackout, but it was not necessarily what first incapacitated her. He tells the police team that she was struck heavily on the back of the head and then thrown among the power lines, while stressing that the report is preliminary.

Restoration and the investigation’s consequences

Power returns to Ystad shortly after three in the morning. The body has been removed, allowing Nyberg’s team to continue examining the transformer building, while technicians search outside for traces. Wallander and Martinsson begin reconstructing how Hökberg arrived. They consider it implausible that she walked to the substation unnoticed and conclude that she was probably driven there. Vehicle impressions include two cars in addition to those belonging to the investigators and Andersson, though the rain has blurred the tracks. The forced gate and apparently accessible keys remain unresolved investigative problems, not proof by themselves of who brought her there.

At a morning briefing, Lisa Holgersson describes the blackout as one of the most serious to hit Skåne and stresses that an event considered impossible has happened. Wallander reports that accident can reasonably be ruled out, but that the evidence has not yet supplied a complete account of either the death or the journey to the station. Ann-Britt Höglund also argues against suicide, pointing to the circumstances of the death; the team nevertheless has to await further forensic findings and establish who could have accessed the keys.

The event makes the power grid’s vulnerability tangible before the investigation reveals the wider threat posed by attacks on interconnected systems. A single body in a transformer building disables supply across a broad region; hospitals switch to emergency generators, police work by portable light, and the restoration effort must find a way around the damaged station. Later, Robert Modin identifies the possibility that compromised financial institutions could precipitate a worldwide crisis. That later plot does not explain Hökberg’s death or establish that the blackout was part of the same operation. Instead, the events place two forms of dependence side by side: the immediate reliance on electrical infrastructure and the less visible exposure of systems linked by electronic networks. The case eventually leaves the motive for Hökberg’s placement among the high-voltage wires unanswered, so the blackout is both a practical consequence of her death and a lasting mystery within the investigation.
