A Silent Fit

Sss... The room darkened into night. I crept away from the open floor, seeking a deeper hollow. Behind the wooden cabinet, a quiet gap opened between the dark wood and the wall baseboard. Step... pause. My stubby feet stepped softly into the narrow slot. A single loose plastic domino lay in the dust. Horizontal. Sharp right angles. I nudged it with my chin, sliding it flush against the vertical skirting board. Click. Sss! A sudden jolt stiffened my legs. Then, stillness. I backed into the snug corner, pressed against the cool wall, nested in the shadows.
