Climb to Safety: Science Fiction

The storm broke overhead as she was carefully hauling herself in through the window on the forty-first floor. Her fingers were bleeding from where she had jammed them into the tiny cracks in the walls to let her climb, and she'd lost a toenail somewhere along the way, but she was safe. She collapsed to the floor inside the building and let herself take a long, deep breath. She'd left a blood-trail, but so far, nobody had been able to prove that the Things could fly, or even climb very well. It was the one and only advantage that the primate-descended human species had.

Inspiration: Stormy Monday - Albert King
Story Potential: Low.
Notes: An interesting little tidbit that I like well enough, but there's nothing extra or unique in this.
