Öland, where Carl and Assad investigate Atu, brings the Nature Absorption Academy’s orderly, expanding community into the same landscape as concealed violence and a police investigation. The island is presented through sharp contrasts: sea-facing buildings and communal projects sit alongside Shirley’s waterless confinement, while Carl and Assad’s arrival turns the Academy grounds into the scene of an assault.

Setting and the Academy

The Nature Absorption Academy stands with the sea just behind it. Its buildings are architecturally polished and arranged in clusters of houses topped with glass domes; near the water, an open space contains the center of a timber circle. The circle recalls structures shown in pictures from Bornholm, linking the island’s Academy to a wider visual world without making the two places identical.

The highway is another conspicuous feature of the grounds. Men work near it, first on the framework for outhouses and, elsewhere on the property, on bicycle sheds. The highway-facing space puts practical construction beside the Academy’s communal and spiritual setting, and provides the approach by which Carl Mørck and Assad reach the grounds.

Expansion and communal life

The bicycle sheds are part of a project intended to support the Academy’s mission on the island. The building materials have arrived on schedule, and the first bicycles are expected later in the week. Pirjo Abanshamash Dumuzi considers the effort in concrete terms: recruiting fifty people on the island would count as success. She is less given to daydreaming than her father, but the recruitment goal shows how the Academy’s presence is meant to grow beyond its existing buildings and members.

Construction also supplies the immediate rhythm of daily life. As work continues outside Pirjo’s window, the workers eventually stop, marking the time for a communal assembly. The scene places organized labor and collective ritual within the same routine; the Academy is not only a set of buildings but a community coordinating work, recruitment, and gathering.

Concealed violence on the island

That outward activity contrasts with Shirley’s imprisonment. Four days after Pirjo turned off the water to the house where Shirley is locked up, she hears faint scratching on its walls during an inspection. She treats the sounds as no cause for alarm and expects them to stop; in a week, she assumes, Shirley will be dead. While the Academy’s projects continue above ground, Pirjo keeps the captive out of sight and lets time become part of the intended harm.

Pirjo’s domestic setting carries another tension: she is pregnant, and the child’s movements have become more moderate over the preceding days. She feels worrying pain in her stomach and considers going to the hospital if it persists. The evidence places this concern beside her plans for the Academy and her treatment of Shirley, setting anticipated new life against a deliberate, concealed threat to another person.

The investigation and attack

Carl Mørck and Assad approach quietly, passing men finishing the outhouse framework. Seeing the people dressed in white, Carl judges the scene too sectarian for his liking and suggests parking farther down the road so they can leave quickly if the community is unwelcoming. The Academy’s composed exterior thus appears to the investigators as a place where they may not be welcome, even before they have established concrete evidence or witnesses.

The encounter becomes violent before the investigation can make progress. As Assad explains that he is trying to unsettle Pirjo because she seems cold and may leave them without evidence, Carl notices a shadow swinging a heavy rubber mallet toward Assad’s head. Before Carl can intervene, another blow hits him. He catches a brief glimpse of a woman bending over him to pick something up. The attack makes the Academy grounds more than a remote setting for inquiry: the island’s carefully maintained order has concealed a direct threat to the investigators themselves.
