Perimeter Assessment

I worked my way down the bookcase rungs and crossed the floor toward a low hum vibrating through the woodwork. Pulling myself up onto the wide painted window sill, I pressed both gloved hands against the glass. The street below was alive with constant movement: cars following lane markers with mechanical rhythm, people briskly crossing the intersection. I tracked their paths from above, measuring the distance to the pavement. The interior is secure; the territory beyond will require exploration.
