The Whispering Gallery

The air in the Whispering Gallery was a compressed, ancient thing, heavy with the scent of damp earth and something metallic, like old blood. Anya paused at the mouth of the vast cavern, her hand a silent gesture for Mykhailo to halt. He’d grown accustomed to her voiceless directives, a language of touch and posture that spoke louder than any shouted command. He followed her deeper, the beam of his sputtering flashlight cutting a shaky swathe through the Stygian dark.

The space opened up abruptly, a cathedral carved by millennia of subterranean water, its ceiling lost in the blackness. The silence here was different – not an absence of sound, but a pregnant stillness that seemed to absorb their footfalls, their ragged breaths. Mykhailo’s heart thudded against his ribs, a frantic drumbeat against the oppressive quiet. He gripped the rough, cool rock wall, his knuckles white. Anya moved with a languid grace, her steps unnervingly light. She stopped perhaps fifty meters into the cavern, turning back to him, her face a pale oval in the dim light.

She made a small, beckoning motion with her fingers, then cupped her hand to her ear. Mykhailo, confused, stayed put. What was she listening for? His own senses were a jangled mess, picking up only the echo of his own fear. Then, Anya deliberately tapped a loose piece of shale against the cavern wall. The sound, sharp and percussive, didn't simply echo; it bloomed. It expanded, distorted, ricocheting off the unseen surfaces until it seemed to come from everywhere at once, a disembodied crack that bounced and shivered in the immense space.

Mykhailo flinched, stumbling back. “What was that?” he whispered, his voice unnaturally loud, then instantly swallowed by the cavern.

Anya made a quick, sweeping gesture with her hand, indicating a wide arc around them. Her eyes, wide and dark, fixed on a point beyond his shoulder. She then mouthed a single word, her lips forming it with exaggerated care: *‘Here.’*

He looked where she indicated, his breath catching. Another sound, fainter this time, a dragging scrape, seemed to emanate from the far wall. It was impossible. He hadn’t made that noise. Anya hadn’t made that noise. It was an intruder. The saboteur.

Anya’s head tilted, as if straining to catch a more distant sound. She held a finger to her lips, then pointed towards a narrow fissure to their left, deeper in the gloom. Mykhailo’s gaze followed her direction. Was he hiding in there? He edged forward, his flashlight beam trembling, illuminating glistening, mineral-encrusted walls. He could hear it now, a faint shuffling, a rustle of movement just beyond the reach of his light.

“He’s there,” Mykhailo breathed, his voice tight with a terrifying certainty. He felt a surge of adrenaline, the hunter’s instinct, raw and unreasoning, overriding the pervasive fear. Anya, standing a few paces behind him, watched him with an unreadable expression, a tiny, almost imperceptible smile playing on her lips. She took a small, smooth stone from her pocket and, with the practiced motion of someone accustomed to playing with such things, tossed it softly towards the fissure. The clatter it made against the rock was amplified, distorted, and then, a moment later, the shuffling sound Mykhailo had heard was echoed back, subtly altered, as if by a third party. Mykhailo’s eyes widened. It wasn’t just him. It was him, and the saboteur, and the impossible acoustics of this place, all conspiring to confirm his hunt. He was so close. He could feel it. The phantom was here.


The amplified echo of Mykhailo’s excited exhalation died a slow, distorted death, its source already lost to the cavern’s immense, mineral-laced maw. Anya ignored the lingering ghost of his breath. Her own breath was shallow, controlled, each inhale a silent calculation. Mykhailo was lost in the symphony of his own delusion, a captive audience to the phantom he’d conjured. That was good. That meant she had time.

She didn’t need the phantom. She needed the patrols.

Her gaze swept the cavern, not for a quarry, but for a soundscape. The Whispering Gallery was a geological anomaly, a vast, curved amphitheater carved by ancient water and salt. Here, a dropped pin could carry for minutes, a whisper could travel a hundred meters, distorted, amplified, a sonic hall of mirrors. Mykhailo saw it as a trap for his quarry. Anya saw it as a listening post, a way to map the unseen.

She’d already heard them, a faint, rhythmic tread that Mykhailo’s panicked state had rendered imperceptible. Russian boots. Heavy, determined. They were using the gallery’s acoustics too, not to listen for phantoms, but for the distant rumble of Ukrainian armor, for the tell-tale sounds of movement in the upper levels. A crude but effective eavesdropping post.

Anya knelt, feigning a search for Mykhailo’s imaginary saboteur near a cluster of stalagmites. Her fingers brushed the damp, gritty floor, feeling for vibrations. She pressed her ear against the cold rock face, filtering out the subtle dripping of unseen water, the settling groans of the earth. There. A metallic clink, too sharp, too regular to be natural. A dropped magazine? A rifle bolt being worked?

She stood and moved silently to another section of the curved wall, her movements fluid and economical. Mykhailo was still a few meters away, flashlight beam dancing erratically, convinced he was on the precipice of a discovery. Anya held her breath, straining to hear the subtle shift in the distant footfalls. She tapped a small, almost inaudible rhythm against her thigh with her knuckles. The sound was swallowed almost instantly. Then, a moment later, she heard it – a faint, distorted repetition, a phantom echo of her own movement. They were close enough that their own sounds bounced back to her, subtly altered.

She closed her eyes, mentally mapping the direction and intensity of the sounds. A patrol moving counter-clockwise. Three, maybe four men. They were methodical, unhurried. They weren’t expecting anyone. They were listening. And she was listening to them.

Anya slipped a slim, metallic stylus from a hidden pocket in her boot. Its tip was worn smooth, almost rounded. She extended it slowly, carefully, and pressed it against the cavern wall. She began to draw, not on paper, but on the damp rock itself, using the stylus to scrape faint lines that would disappear with a bit of moisture. A rough circle for the gallery, then directional arrows indicating the patrol’s movement. She added a small, dense cluster of dots where she’d heard the distinct metallic clink.

Suddenly, a harsher, more resonant sound boomed through the gallery. A guttural command, amplified and distorted into an alien roar. Mykhailo yelped, his flashlight beam snapping towards the sound. Anya froze, her heart hammering against her ribs. The command was followed by a series of sharp, percussive thuds, like rocks being thrown against the wall. They weren't just listening; they were probing. Testing the acoustics.

Anya’s hand shot out, her fingers finding Mykhailo’s arm, pulling him back with surprising strength. Her eyes, wide and urgent, met his. She didn't speak, but her gaze conveyed a stark, unvarnished truth: danger. Real, immediate danger, not the phantom he was chasing. She pointed sharply back the way they had come, then gestured for silence, her hand pressed flat against her mouth.

Mykhailo, disoriented by the sudden shift in Anya’s demeanor, his imagined hunt momentarily forgotten, nodded mutely. The amplified command, a guttural Russian obscenity, echoed again, closer this time. It was no longer a distant sound. It was a presence. Anya didn't wait for him to process. She was already moving, a shadow detaching itself from the wall, melting back into the deeper gloom, urging him to follow, her silent urgency a more potent command than any shouted order. The gallery, which had seemed like a stage for Mykhailo’s delusion, had suddenly become a very real, very dangerous labyrinth.
