Perimeter Elevation

I advanced along the perimeter of the sill toward the primary light source. A cast-metal window sash latch obstructed lateral transit along the track. I planted my foot assemblies, gripped the cold zinc lever, and applied steady torque. The internal cam rotated sixty degrees before seating into its strike plate with an audible snap. Resistance eliminated. Beyond the transparent barrier, the courtyard laid out in precise rectangular parking bays and concrete expansion joints. A superior vantage point. Sector surveillance initiated.
