So she climbed the extra three stories to the twenty-fifth floor. She took the stairs, as to not arouse suspicion.
Even though she didn’t know the people who lived on those floors, she did not want anyone, familiar or not, interrupting.
Her chosen route proved to be the most discreet option; during the ascent she did not see or hear one resident.
As the stairs wound around above the final residential floor, they ended abruptly at a locked door. It was a compelling sight.
It was a plain, white door; no different any other one. But it was doused in an ominous blue haze, which seeped around its edges. An electric blue.
A crescendo of noise had built as she went up the steps. A menacing hum enveloped her and each time she got higher it grew thicker around her.
At the very last step she tried the handle but the door didn’t budge. Warning signs littered the stairwell, yet were unable to prevent her from lingering curiously.
