An ear perked.

Someone was here.

He could hear it, the gentle sloshing of someone wading through the ankle-deep water that flooded the floor.

When he moved, the figure sloshed around too.

When he stopped, whatever it was stopped a moment or two later.

Strange.

He kept moving though, a slow, careful walk, his footsteps muted atop the ice that froze under his feet with every step. His ears perked, listening in to the sounds that echoed through the narrow, empty halls.

Sooner or later he'd stumble upon the fellow that was stalking him.

Sooner or later.
