The old boarding school stood on a mist-shrouded hill in northern India, a relic of a bygone era with its colonial-era architecture and stone-grey walls. For the children who lived within its hallowed halls, the corridors echoed with more than just the clamor of school bells and hurried footsteps; they whispered tales of the supernatural. The most enduring of these was the legend of "Chalk-wali Didi," the spirit of a teacher said to haunt the classrooms after dark.
Ten-year-old Sameer, new to the disciplined life of the boarding school, found these stories to be nothing more than childish fantasies. His dormitory mates would speak in hushed tones about the ghost of a teacher who had met a tragic end on the school grounds decades ago. They warned him never to leave a blackboard unerased, for Chalk-wali Didi was known to finish the lesson herself.
"Nonsense," Sameer would scoff, "You’re all scared of a little story." He made it a point to defy the unwritten rule, often leaving mathematical equations half-solved on the board, a silent challenge to the ghostly teacher.
For a while, nothing happened, and Sameer felt vindicated. Then, the strange occurrences began. One morning, a complex geometry problem Sameer had left unsolved was found completed, the answer written in an elegant, almost unnervingly perfect script. His friends were terrified, their eyes wide with a mixture of fear and accusation.
Sameer’s skepticism began to crack. He started hearing faint, inexplicable noises at night—the soft, rhythmic tap-tap-tapping of chalk against a board, a sound that seemed to emanate from his empty classroom down the hall. Books he left open on his desk were found neatly shut, and a misplaced protractor would reappear, placed precisely on his textbook.
The ghost stories his grandmother used to tell, once a source of amusement, now played on his mind. He recalled tales of spirits tied to their place of death, forever repeating their last actions. The legends of the school, which seemed so distant before, now felt uncomfortably close.
One night, a fierce thunderstorm raged outside, rattling the windowpanes of the dormitory. A power cut plunged the school into an inky blackness. Sameer, waking with a start, felt a pressing need to use the restroom at the far end of the corridor. With a gulp, he slipped out of his bed and into the darkened hallway, the floorboards creaking under his bare feet.
As he tiptoed past his classroom, he heard it again—the distinct tap… tap… tap of chalk. He froze, his heart pounding in his chest. A dreadful curiosity, mingled with a primal fear, compelled him to peek through the small glass pane on the classroom door.
A flash of lightning illuminated the room, revealing a tall, slender figure in a simple, pale saree, her back to the door. She was writing furiously on the blackboard, her long, dark hair obscuring her face. As another bolt of lightning lit up the sky, the woman began to turn, her movements slow and deliberate.
Sameer’s breath hitched in his throat. The woman’s face was a pale, spectral white, but her eyes were just dark, empty sockets. A silent scream seemed to emanate from her gaping mouth, and the piece of chalk in her hand snapped in two with a sharp crack that echoed in the silent room.
A blood-curdling scream escaped Sameer’s lips as he stumbled backward and fainted. The next morning, the school watchman found him, feverish and incoherent, muttering about a woman with no eyes. He was promptly sent home, his parents informed that he was suffering from a severe bout of altitude sickness.
But the students of the old Indian school knew the truth. The story of Sameer became another cautionary tale, whispered in the dormitories for years to come. And no child, ever again, dared to leave the blackboard unerased.
