Cosmic Signal

I moved across the wide wooden sill toward the dark window pane. Outside, tiny pinpricks of city light mirrored the stars. I spotted a round brass key lying beside a glass prism. I pushed the flat edge of the brass key against the glass base to form a rigid fulcrum. Then I rocked my yellow dome upward onto the prism's crest. The angle aligns. Streetlamps below scatter through the faceted glass into geometric beams across my chest. The observation post is fully operational.
