The Staircase

Marcus counted the stairs every day for twelve years, there were always twelve steps, until the morning he found a thirteenth step that led somewhere impossible.

Marcus Webb had lived in the same townhouse in Philadelphia since he was eight years old when his parents purchased it in 1998, and the house was old, built in 1887, with creaking floors, drafty windows, and the quirks that come with Victorian architecture, but it was home and Marcus knew every detail of the place including the staircase connecting the first and second floors which had exactly twelve steps, he had counted them thousands of times over the years, bored childhood counting that became unconscious habit that persisted into adulthood. On a Tuesday morning in March 2024, Marcus was descending the stairs on his way to make coffee before work, and his foot reached for the expected floor at the bottom of the twelfth step, but instead it found another step, a thirteenth step that definitely had not existed the night before when he had climbed the same stairs to bed.

Marcus stopped mid-descent, his brain struggling to process what his body was experiencing, and he looked down at his feet to confirm what he was feeling, and there was indeed a thirteenth step, matching the others in size and appearance with the same worn oak finish and the same slight creak when weight was applied, and it seemed to always have been there, except Marcus knew with absolute certainty that it had not existed for the twelve years he had lived in this house. He backed up to the landing and counted carefully, one, two, three, all the way to thirteen, and then he counted coming down, and thirteen steps were definitely present, and he felt dizzy and confused because this made no sense, you cannot add a step to a staircase overnight, physics and reality do not work that way.

Marcus convinced himself he had simply been wrong about the number of steps all these years, that there had always been thirteen and he had miscounted or misremembered, human memory is fallible after all, and he continued down the newly discovered thirteenth step to the ground floor and proceeded with his morning routine, but the wrongness of the situation nagged at him throughout the day. That evening he measured the staircase carefully and discovered something impossible: the thirteen steps occupied the exact same vertical distance that twelve steps had previously occupied, meaning each individual step was slightly shorter than it should be, and the staircase still connected the first and second floors exactly as it always had despite containing an additional step that should have made it taller by approximately seven inches.

Over the following days, Marcus became obsessed with the staircase, photographing it, measuring it repeatedly, and researching the house's history for any mention of modifications or anomalies. He discovered that the house had been built by a architect named Edmund Blackwood who had studied sacred geometry and numerology and who had believed that certain architectural configurations could create doorways to other dimensions or states of being, and Blackwood had disappeared in 1889, two years after completing this house, with witnesses reporting that he had last been seen entering the house he had built and had never emerged, though searches found no trace of him and no evidence of foul play.

On the seventh night after the thirteenth step appeared, Marcus woke at 3 AM to the sound of footsteps on the stairs, slow deliberate steps descending from the second floor, and he lay frozen in his first-floor bedroom listening to the creaking progression, and he counted each creak, twelve steps creaked in the familiar pattern, and then there was silence for approximately ten seconds, and then a thirteenth creak sounded, the new step, and then nothing, no further sounds, no doors opening or closing, just the thirteenth creak and then silence. Marcus gathered his courage and opened his bedroom door to investigate, and the staircase was empty in the dim light from street lamps filtering through windows, but standing at the base looking up, he saw that the stairs seemed to extend higher than they should, that looking up from the bottom it appeared there might be more than thirteen steps, though counting was difficult in the poor light and from this angle.

He began climbing, counting each step carefully, and when he reached what should have been the thirteenth step and the second-floor landing, he found instead a fourteenth step, and above that, darkness that his eyes could not penetrate, and he understood that the staircase was growing, that it was extending upward into some space that did not exist in normal geometry, and he knew he should stop climbing, but curiosity and some compulsion he did not fully control drove him upward, fourteenth step, fifteenth step, and the air was getting colder and the darkness deeper, and at the twentieth step he heard a voice from above, a man's voice, refined and old-fashioned in diction, saying "Welcome, I have been waiting for someone to find the way," and Marcus fled back down the stairs, counting backward, nineteen, eighteen, eventually reaching the first floor and his bedroom where he locked the door and pushed furniture against it.

Marcus moved out of the house the next day, staying with friends while he arranged to sell the property, and he never returned inside, hiring movers to pack his belongings and having the house sold fully furnished to buyers who got an excellent price for a Victorian townhouse in that neighborhood. He does not know if the new owners have noticed the thirteenth step or if it continues growing, and he does not want to know, because some doors once opened cannot be closed, and some staircases lead to destinations that humans were not meant to reach, and the architect who designed impossible geometries into that house in 1887 may still be climbing stairs that extend forever into darkness, counting steps that no longer correspond to any earthly dimension.
