By now, everyone looking at the illustration had developed a different theory. Some believed the chicken was hiding inside the cave, while others insisted it was somewhere along the outer rocks. We compared observations, examined the shadows, and tried to connect the unusual curves.

I followed the outlines one final time, slowly connecting the shapes. Suddenly, the possibility became impossible to ignore.
