Present
After securing the rooftop door she came through, Ada turned and sprinted down the stairs taking two or three at a time. She felt each impact in her ankles, but she will be damned to take another chance to lose her distance. They were hot on her tail and she was going to make the best of this chance she had while she was unseen from them. Her throat burned as she pulled in breaths.
At the bottom landing, she leapt the last four stairs. She landed awkwardly, stumbling and falling down on one knee as she grabbed the door handle. She righted herself, pushed down on the handle and yanked it open. She burst into the darkness, pulling the door shut behind her. Through the door she just shut she heard the snapping of wood reverberate through the stairwell.
