This subplot traces how a financially motivated renovation creates both the disturbance around Anna and the hiding place later revealed by Hal.

Work by the Flat

Work by the Flat A Building in Transition The old apartment building is being modernized one unit at a time to preserve rental income. Sawing and hammering disturb residents still living in the surrounding flats. A Domestic Burden The work intensifies the discomfort of Anna, already in poor health. What looks like routine maintenance becomes part of the circumstances surrounding the household's crisis.

The Upper Flat Finished

The Upper Flat Finished Uneven Progress The top apartment has been completed but remains unrented, while work continues on the floor below. The building's staggered renovation leaves distinct stages visible at once. A Future Clue The finished upper unit initially seems irrelevant to Hal's suspicions. Its location later becomes central because it sits directly above Lars's home.

A Visitor in the Sixth Floor

A Visitor in the Sixth Floor A Passing Pair A landlord shows a prospective tenant the completed upper apartment while Lars moves through rooms below. Their simultaneous passage between windows catches Hal's attention. A Disturbed Symmetry The two figures seem to change relative height as they move. Hal cannot initially explain the visual hitch, but the memory remains available for later reasoning.

The Kitchen Floor's Rise

The Kitchen Floor's Rise Construction Detail Reconsidered Hal remembers that cement floors were being raised, with a dropped living-room effect planned economically. The strange difference in apparent height now has a concrete architectural explanation. A Hidden Space The recently altered kitchen floor could cover a body without disturbing Lars's own rooms. Renovation shifts from background noise to the key to locating Anna.

The Unfinished Unit Searched

The Unfinished Unit Searched A Specific Destination Hal directs the police to the fifth-floor rear apartment, where the cement kitchen surface differs from the other rooms. The explanation is precise enough to guide a search. The Renovation's Final Meaning The floor's alteration has hidden the body, while the workman's materials and unfinished status explain how the concealment could have been carried out. The building itself has become evidence.
