A Timetable of Windows
Repeated Movements
Hal learns when lights come on, when residents leave, and how familiar figures move through their rooms. He can map habits without knowing names or hearing voices.
A Private Method
Observation offers structure during his restricted days. These repeated patterns later give small deviations unusual importance.
The Lights Stay Up

The Lights Stay Up
A Change in Pattern
Lars's flat remains dark and still through a day when its shades do not move, then lights come on after he returns. Hal realizes he has seen no sign of Anna.
A Broken Link
The absence of the usual response at home feels more significant than any single gesture. Hal begins to treat routine as a form of evidence.
No Greeting at the Door

No Greeting at the Door
An Expected Response Missing
Lars returns, but Anna does not come out to meet him. Hal notes that the customary domestic pattern has failed.
Observation Becomes Suspicion
A missed greeting could have an innocent cause, such as illness or sleep. In combination with Lars's refusal to check on her, it becomes part of a troubling accumulation.
The Bedroom Remains Untouched

The Bedroom Remains Untouched
An Odd Choice
Lars spends the night away from the bedroom, though two beds are available there. Hal finds the choice inconsistent with the claim that Anna has already gone away.
Routine as Negative Evidence
What Lars does not do matters as much as what Hal sees him do. The untouched room becomes a clue precisely because Hal knows what its ordinary use should be.
The Pattern Becomes a Case

Revisiting the Deviations
Hal assembles the late hours, missing greeting, packing, drinking, and avoidance of the bedroom. No one detail proves murder, but together they resist the travel explanation.
A Habitual World Reversed
The domestic routine that first seemed trivial becomes a diagnostic tool. Hal's case depends on noticing a broken pattern and waiting for its meaning to emerge.
