Perimeter Descent

I located a stack of hardcover books bridging the shelf to the sofa back. Testing the first spine with my boot, I confirmed adequate traction. Descent required deliberate pacing. Once I reached the cushion, I crossed to the coffee table. A glass tumbler sat near the edge, casting a curved shadow under the dim room lamp. I circled the base twice. Clear line of sight across the entire carpet floor. A tactical advance accomplished.
