Flash Fiction: Working Late

The hallway was dark, all but one of the motion-activated lights unlit for the past hour.
 
A crash interrupted the stillness. 

The building was secured. Everything was fine. Just someone else working late.

Footsteps sounded in the hallway, steady and firm.

As they drew closer, only a few yards away now, she waited for the lights to react to the motion and turn themselves on. 
​
The hallway remained dark.
