He didn't put the key in the lock. Instead, he looked at the door and realized that the number wasn't 999. Depending on how you stood, it was 666. It was an upside-down reflection. The door wasn't an exit; it was a mirror.
Elias took the key out of his pocket and let it drop into the darkness of the stairwell. He didn't open the door. He simply sat on the 999th step and watched the sun finally break through the clouds over the Bosporus. The loop was broken because he stopped trying to finish it.
He reached for the handle. But this time, he remembered Ilhan’s sketch. The circle that didn't close.
Elias reached the final landing. Before him stood a heavy wooden door, carved with the numeral . It was the same door he had reached nine hundred and ninety-eight times before. Every other time, he had turned the key, walked through, and found himself standing back at the base of the tower, the rain still hanging in the air, the count reset to zero.
Nine hundred and ninety-seven. Nine hundred and ninety-eight.
