A Hidden Map

I slipped quietly into the netted pouch behind the empty seat in front of me, seeking shelter as the carriage lights dimmed for the night. Down in the corner, nestled beside an abandoned plastic water bottle, was an unfolded safety brochure. I steadied my footing against the dark fabric netting and tugged on the thick paper until a hidden diagram caught my eye. It showed cross-sections and numbered pathways through the train that I hadn't noticed while wandering earlier. Crouching low in the shadows, I traced the tiny printed routes with my fingertip, memorizing each junction before settling in to rest.
