Poland links Piet Hoffmann’s family history to the novel’s investigation of the drug trade. It appears first as a destination freighted with childhood recollection and later as the site of a ruined amphetamine factory, connecting an intimate sense of displacement with an international criminal economy. The country is not simply a backdrop: it is a recurring point on the route between the investigation in Sweden and the production networks the investigators are trying to understand.

Personal memory and return

Hoffmann’s journey to a city larger than Stockholm begins in the present with a small overnight bag and a taxi ride. The city itself is not named in the passage, but his work with Wojtek International gives the visit an established context: for three years, he has travelled to the organization’s head office each month to meet Henryk Bak. On this occasion, Henryk confirms their arrangements and tells him that Zbigniew Boruc, the deputy chief executive, and Grzegorz Krzynówek, known as the Roof, will also attend. The repeated business visits make Poland familiar territory in one sense, while the people joining the meeting signal the weight of the organization’s hierarchy.

The journey also opens onto a much older passage through memory. Looking out at a city that has changed beyond recognition, Hoffmann recalls being a child between his parents in the back seat as they travelled from Stockholm toward Bortoszyce, close to the Soviet border. His parents called the region by its former name, Konigsberg, and rejected the later name Kaliningrad; as a child, he registered their contempt without understanding why they had left the place they longed for. The recollection supplies no full account of the family’s departure, but it establishes Poland and its borderland as part of a history inherited through his parents’ attachment and refusal. His adult return is therefore both practical and shadowed by a childhood landscape he could not then comprehend.

The investigation leads to Siedlce

Poland becomes a different kind of destination when Ewert Grens and Sven Sundkvist follow up on yellow stains that Nils Krantz found on an item of clothing. Their inquiry takes them to Siedlce, about a hundred kilometres east of Warsaw, where they find the remains of an amphetamine factory. The factory is no longer operating in the form they investigate; its ruins nevertheless give the material clue a location and connect the Swedish case to production beyond Sweden. The sequence matters: a trace on clothing prompts a journey, and the journey ends not with a functioning enterprise in view but with physical remains that point toward a wider supply chain.

The novel also widens the frame around that site. Grens and Sundkvist work for several days with some of the three thousand police officers assigned to a special force combating organized crime. The account describes a landscape of five hundred criminal groups contesting the Polish domestic market and eighty-five larger groups with international connections. Police, it says, frequently take part in armed confrontations, while synthetic-drug production brings in more than five hundred billion kronor each year. These figures place the factory remains within a large and violent criminal economy rather than presenting them as an isolated discovery. They also register the scale of the challenge confronting the investigators: evidence can lead them to a place, but the networks around that place extend far beyond a single site.

A recurring point in the criminal geography

The investigation’s return to Poland is compressed into Grens’s recognition that the country has appeared in his work before. That recurrence gives the location a procedural as well as geographical meaning. Yellow staining, examination of clothing, and the eventual visit to Siedlce make Poland part of a chain of forensic and investigative reasoning; the country is reached by following evidence, not introduced merely to enlarge the setting. At the same time, the ruined factory and the reported reach of organized groups caution against treating one recovered clue as a complete explanation of the trade.

Poland consequently holds two distinct positions in Hoffmann’s story. For him, it is associated with Wojtek International’s business centre and with his parents’ unresolved attachment to a place they left. For Grens and Sundkvist, it is where a clue from a Swedish case leads to the remains of a production site and to cooperation with a large police operation. The two strands do not resolve into one personal or criminal explanation. Instead, their juxtaposition makes the country a crossing point between private memory and transnational investigation: a place that Hoffmann revisits for work, remembers through his parents’ longing, and that the police reach by tracing material evidence.
