The office on Runnerströms Torg is Tynnes Falk’s separate workroom and a pivotal site in the investigation: a sparse room where small physical traces sit beside a computer concealing an international network. Kurt Wallander returns to it to search for what earlier inspections may have missed, and later Modin and Martinsson work there to penetrate Falk’s computer. The room’s apparent emptiness does not mean it is inactive or safe; it becomes a watched space in which each new discovery raises the stakes.

Setting and Discovery

Kurt Wallander reaches the building after parking on Jörgen Krabbes Väg and walking over. The office is on the top floor. Its austerity gives the search a particular character: on an early visit, the computer and a power-substation blueprint seem to account for nearly everything in the room. Wallander looks around as he did the first time, wondering whether he and Nyberg overlooked something, but initially finds nothing. He sits at the dark computer, faced with the limits of what a careful visual inspection can reveal.

The room’s plainness makes a concealed postcard all the more significant. After a phone call ends in static and silence, Wallander lifts the keyboard without thinking and finds the old card beneath it. Its faded image shows a tropical bay, palm trees, a pier, fishing boats, and tall buildings beyond the shore. Addressed to Tynnes Falk at the Apelbergsgatan address, it bears only the letter C as a message; the partly torn stamp yields too little to establish where or when it was sent. The card complicates Siv Eriksson’s understanding that she received all Falk’s mail, though her spontaneous surprise leaves Wallander unsure whether she had known of another correspondence or address. Its placement turns an apparently bare office into evidence of a private life that had not been fully accounted for.

Surveillance and Unease

The office is also part of a surveillance operation, but the watch is imperfect. While officers keep an undercover car near Falk’s building, a navy blue Mazda saloon passes several times from the direction of the Malmö road. It slows on its first two passes, according to El Sayed, and returns after about twenty minutes without slowing. The officers think there is only one person inside. Their colleagues watching the office at Runnerströms Torg have not seen the car, a discrepancy that leads Wallander to consider whether the watcher knows only about Falk’s flat—or whether the office watch has failed.

The registration number is MLR 331, but the computer system needed to check it is down. Wallander instructs the officers to write a report and pass it to Hansson or Martinsson; he tells them not to intervene if the car returns, since no crime has yet been established, but to call him. When he reaches the office, he gives its officers the number and tells them to keep watch. The episode makes surveillance feel provisional: the investigators can record a vehicle and tighten attention, but cannot yet identify its occupant or explain the purpose of the visits.

That uncertainty intensifies when the office phone rings. Wallander answers on the seventh ring and hears breathing amid long-distance-like static before the connection clicks off. The sound recalls the messages he had heard on Falk’s phone. He considers whether the caller sought Falk, or had seen Wallander enter the building and was calling him instead; the possibility revives his anxiety about the recent attempt on his life. In the next chapter, a shadow retreats into the darkness near Runnerströms Torg as Wallander arrives. The undercover cars have not deterred whoever is watching. The text does not identify the watcher, leaving the office’s surveillance as an unresolved threat rather than a solved clue.

Falk’s Hidden Record

The postcard links the room’s objects to the larger pattern of signs around Falk. Wallander recognizes that its C resembles the C in Falk’s diary and concludes that Falk had known who or what it referred to. Yet the card supplies no location, date, or explanation: its tropical image suggests a place without naming one, and the surviving marks on the stamp remain indecipherable. Wallander pockets it, examines it again at home with a magnifying glass, and still learns nothing further. The clue is concrete but incomplete, extending the investigation without resolving it.

The computer creates a different kind of opacity. Modin had noticed the number 20 in Falk’s numerical material, but Wallander cannot see the pattern himself. He wonders whether it relates to the approaching October 20 or the year 2000, without knowing whether either interpretation bears on the case. The room thus holds two forms of evidence: a physical card whose few marks resist interpretation, and a mass of digital information whose order becomes visible only to a specialist. In both cases, Wallander must acknowledge what he cannot yet read.

The Computer Investigation

When Modin finally gains access to Falk’s computer, Wallander hurries to the office to see the results. He finds two new computers beside Falk’s and Modin and Martinsson concentrating on the screens. The chaotic swarms of numbers have given way to more orderly arrangements. Modin moves among three keyboards, while Martinsson records what he dictates. Their changed setup embodies a practical breakthrough: unable to discover the password, Modin has brought in his own computers and connected them to Falk’s, entering through what he describes as a back door. He declines to explain the technique in detail.

The files reveal a network rather than a simple jumble. In a file named Jacob’s Marsh, the investigators find ordered phone numbers, names, codes, and long number combinations associated with institutions in different parts of the world. Their subsequent identifications include the National Bank of Indonesia, Lyder Bank in Liechtenstein, a French telecommunications firm, and a commercial satellite company in Atlanta. The office is therefore not merely where Wallander searches for clues; it is the working site where Falk’s carefully arranged digital relationships begin to take shape for the investigation. Modin insists that the organization is deliberate even though it is not alphabetical or numerical, and Martinsson’s notes help translate that observation into leads.

Narrative Significance

The office gathers the investigation’s central contrast between ordinary rooms and concealed systems. At first it offers little to see: a computer, a blueprint, and a dark phone. Yet a postcard beneath a keyboard unsettles assumptions about Falk’s mail, repeated calls and passing cars make the site feel exposed, and the computer yields connections to banks and communications companies across several countries. Each discovery changes what the room means without making it transparent.

Its function also shifts from a place Wallander searches alone to a shared investigative workspace. He studies the room and its clues; later, Modin’s technical skill and Martinsson’s record-keeping make its computer legible in ways Wallander cannot manage by himself. At the same time, the shadow outside shows that access to the office is not the investigators’ alone. The location concentrates evidence, collaboration, and danger, while preserving uncertainty about who is watching and what Falk’s network was meant to do.
