Acoustic Survey

Morning light hit the wooden collar stay bridging the book gap. I dismantled the perimeter platform and stepped past the glass marble marker to the forward edge of the walnut shelf. The drop to the floor below is clear. Wedged beneath the corner of an upright volume, I spotted a detached silver metal watch crown. I gripped the ribbed cylinder with my right hand clamp, slid it free, and aligned it on the wood grain. Tapping it with my left clamp sent a crisp metallic resonance along the rim. Sector vantage mapped.
