Establishing Perimeter

The climb up the book spines required measured footing. Once on the highest shelf, the entire living room unfolded below. I surveyed every entry point, from the shadow under the sofa to the hallway arch. A heavy brass paperweight beside a row of encyclopedias offered solid anchor support. I conducted a systematic sweep of the perimeter in the quiet dimness, confirming zero movement. Sector clear. A prime observation post.
