A Smooth Discovery

I walked slowly along the skirting board, following a faint, cool draft. In the shadowed gap beneath the bookshelf, my snout bumped something cold and hard. I paused. It didn't move. I nudged it gently with my front paw, rolling it out into the dim light. A small, clear glass marble. Perfectly round, catching a soft amber gleam from the hallway lamp. I rested my chin against its smooth surface, letting the cool glass steady me. It felt nice to stay right there.
