St Johannes Cavern is an underground refuge beneath St Johannes Church in Stockholm, inhabited by people who have fallen outside the protection of ordinary society. Its makeshift settlement offers shelter and a measure of community, but the discovery of Fredrika Grünewald’s body exposes the danger that can persist within a place marked as safe. The cavern’s meaning rests on this tension: it is at once a response to homelessness and the scene of a murder.

Setting and Social Context

The cavern lies beneath St Johannes Church in Norrmalm, in the large spaces below the church. The narrative situates it within a shortage of shelter in Stockholm: the city has approximately two thousand shelter beds for five thousand homeless people, many of whom have alcohol or drug problems. Around half are also described as experiencing some form of mental illness. Competition for beds can lead to fights, and some people choose to sleep elsewhere. These figures place the cavern not as an isolated curiosity but within a broader failure to provide enough places to stay.

People have formed colonies in the caverns, sharing the circumstance of being beyond ordinary social protection. The damp, cathedral-like space offers something resembling security. Their shelters are assembled from plastic or tarpaulin, cardboard, and sleeping bags; their quality varies, with some built more carefully than others. That variation matters: the cavern is not simply a mass of people sleeping in an undifferentiated space, but a settlement in which occupants make individual places to live from what is available.

The Swedish Order of St Johannes has been active since the twelfth century under a motto expressing aid to the poor and sick. The use of the church’s underground chambers as refuge seems to echo that charitable purpose. At the entrance, a banner shows the Order’s emblem: a white cross on red, presented as a sign that anyone might be safe there. Yet the emblem’s promise is not reliably fulfilled. The murder in the caverns turns its apparent assurance into an ironic contrast between the declared welcome and the danger discovered below.

A Makeshift Settlement

When Jeanette Kihlberg enters the cavern as part of the police response, floodlights powered by a generator illuminate an underground settlement arranged around tents, boxes, shelters, and small fires. The constructions range from carefully made homes to rudimentary dens. Despite the disorderly collection of materials, Jeanette perceives a sense of order and an underlying wish for structure. The place is improvised, but its inhabitants have made distinctions, boundaries, and routines within it.

Among the sleeping bags, rubbish bags, boxes, and clothes, Jeanette notices a small shelf of books. A sign says that the books may be borrowed if they are returned. This modest arrangement complicates assumptions that homeless people lack interest in culture or intellectual life. Jeanette reflects that the circumstances leading someone into the cavern may be as ordinary as bad luck, unpaid bills, or depression. The shelf is one concrete sign that the settlement contains practices of exchange and care, not only the urgent business of finding somewhere to sleep.

The cavern therefore serves as a fragile alternative to the city’s limited shelter provision. Its residents build shelters and create shared arrangements, while the scale and material conditions of the space keep those arrangements provisional. The narrative does not present it as an officially administered institution; instead, its order emerges from the people living there and the objects they assemble around themselves.

Routes into the Cavern

A woman approaches the church in search of a place where she might stay and begin again. She imagines changing her name and clothes and leaving her past behind. As she walks along the churchyard railing, she hides her blonde hair beneath a woolly hat. Her movement toward the caverns is thus both practical and directed toward a possible new life, although the refuge she seeks cannot erase the memories she carries.

She follows directions given by a beggar, going around to the opposite side of the church to find the entrance. On Döbelnsgatan, roughly fifty metres ahead, she sees a figure beneath a tree beside a partly open grey metal door; voices can be heard inside. The door and the man beside it mark a threshold between the street and the hidden settlement. After he challenges her, she gives him three hundred-krona notes, and he holds the door open for her to enter.

A long staircase leads down to the cavern. Once her eyes adjust, she sees a faint light below; at the bottom, the space opens into a chamber compared in size to a football pitch, with a roof about ten metres high. Tents, boxes, and shelters are arranged around small fires, while people sit or lie nearby. The scene is notably quiet, with only low conversation and snoring described. The cavern is concealed beneath a familiar public building, yet its size and population form a separate world below street level.

Murder and Narrative Significance

The cavern becomes a crime scene when Fredrika Grünewald is found murdered there. Woken at half past six, Jeanette receives an order from Police Commissioner Dennis Billing to come into the city as quickly as possible. She leaves a note and money for Johan, calls Jens Hurtig, and arranges to meet him outside because he has heard that the atmosphere among the residents resembles a lynch mob. The urgency of the response registers how the murder has unsettled the settlement as well as brought the police into it.

Inside, Fredrika is identified as the woman known as the Duchess, supposedly from a noble family, though the police are still checking that account. Hurtig points Jeanette toward a tent made from large plastic bags, with a worn blue blanket hanging over its entrance; Fredrika lies inside. The improvised shelter that represents a resident’s home becomes the immediate focus of the investigation. The evidence supplied does not establish who killed her or resolve the Duchess’s claimed background, so the cavern’s role here is as the site of discovery and inquiry rather than a source of a completed solution.

The police floodlights and generator transform the cavern for the investigation, making its shelters and pathways visible to Jeanette in a new way. She moves carefully through the settlement and encounters, alongside the murder scene, the book shelf and the signs of an everyday order. That juxtaposition prevents the place from being reduced to a criminal backdrop. St Johannes Cavern remains a refuge made necessary by scarcity, but its emblem of safety cannot protect every person who seeks shelter there; the murder makes that failure visible.
