The stench of brine and diesel fuel clung to the air, heavy and rancid, even within the cavernous warehouse. Rain lashed against the corrugated iron roof, a furious drumbeat drowning out the distant city hum. Grigoriy Belov stood beneath a bare bulb, its anemic glow casting sharp, dancing shadows across his face. He wasn't looking at the stacks of crates, nor the hulking container ship visible through the open bay door; his gaze was fixed on the man before him, Kostiantyn, whose face was already a mottled map of dread. “A minor error,” Kostiantyn stammered, his voice a reedy whisper over the rain. His hands, calloused from years of dock work, wrung together. “The manifest… one digit off, boss. The authorities didn’t even notice. We got them through, twenty-three in total.” Grigoriy’s lips, usually curved in a charming, almost benevolent smile for society, thinned into a razor’s edge. “Twenty-three, dockhand? Not twenty-four?” He took a step closer, the expensive leather of his boots crunching on scattered wood shavings. The foreman flinched, shrinking back against a stack of burlap sacks. A predatory stillness tightened the room. “One… one slipped away, boss. A young one. She was sickly, weak. She just… disappeared in the chaos. We searched, I swear it.” The dockhand swallowed hard, his throat dry. Grigoriy reached out, not with a fist, but with a slow, deliberate hand. He plucked an iron nail from a wooden pallet beside the dockhand’s head. He turned it over in his fingers, its jagged tip catching the dim light. “Disappeared,” he repeated, the word a soft hiss. “Do you understand what an unaccounted asset means to my operation? It means a loose end. A whisper. A potential crack in the foundation I have so painstakingly built.” He didn't raise his voice. That was the chilling part. His tone remained conversational, almost regretful, as he brought the nail’s point to Kostiantyn’s left index finger. A bead of sweat trickled down the dockhand’s temple. “My logistics are flawless,” Grigoriy continued, pressing the nail just under the cuticle. “My network, impenetrable. And you are a cog. Small, insignificant, perhaps. But even a small cog, if it breaks, can jam the entire machine.” Kostiantyn gasped, a stifled, strangled sound, as Grigoriy, with agonizing slowness, twisted the nail. Blood welled, dark and glistening, blooming beneath the skin. Kostiantyn’s face contorted, but he made no sound beyond a choked whimper. He knew better than to scream. “Consider this a… re-calibration,” Grigoriy murmured, finally pulling the nail free. The man clutched his bleeding finger, tears streaming down his face, silent and hot. “Next time, ensure your count is precise. Or you will be the one who disappears.” Grigoriy wiped his fingers fastidiously with a silk handkerchief before tossing it onto the blood-spattered floor. He turned and walked away, his silhouette disappearing into the gloom, leaving the foreman trembling and alone with the relentless rain. *** The alley reeked of stale beer and desperation. A flickering streetlamp barely pierced the pre-dawn murk. Detective Milos Novikov knelt beside the body, the grim familiarity of the scene a dull ache behind his eyes. Another one. The ninth. The victim was barely twenty, her dark hair fanned out on the grimy cobblestones. Her clothes, simple and worn, suggested a life far from the gilded salons of the city’s elite. But it was the detail on her lips that drew Milos’s focus, a signature he knew all too well. A shard of glass, vibrant and impossibly blue, rested delicately on her lower lip. It caught the faint light, gleaming with an almost otherworldly intensity. Cobalt. Always cobalt. The ‘Shadow Collector’s’ macabre calling card. “Anything, Milos?” demanded Inspector Zoryana Krylov, her voice gravelly with fatigue. She stood a few feet back, surveying the scene with a practiced, weary eye. Milos, without looking up, carefully lifted the glass shard with gloved tweezers and placed it into an evidence bag. “Same as before. No signs of struggle, no obvious cause of death. Posed. And the glass.” He held up the bag. “This particular shade. It always reminds me of the Grand Cathedral’s windows.” Krylov grunted. “The old relic, yes. Some of those pieces are centuries old, unique. You’ve said that before.” “It’s not just the color,” Milos clarified, rising slowly. His gaze drifted from the victim’s serene, unsettlingly peaceful face to the grimy brickwork surrounding them. “It’s the composition. I had a sample analyzed after the fifth victim. It’s an antique blend, the kind only master artisans would work with. Specific fluxes, specific pigments. Not something you’d find in a modern stained-glass studio. Not even in a high-end one.” He walked over to his cruiser, pulling a worn leather-bound notebook from his coat pocket. He flipped through pages filled with meticulous notes, sketches of the glass shards, and lists of art historians and restorers he’d already interviewed, all of them dead ends. He paused at a section, tapping his pen against the page. “The Grand Cathedral underwent a major restoration fifteen years ago, after the fire,” he mused aloud. “They brought in the best. Specialists from across the continent. I’ve been through the official reports, the restoration committees, the workshops. But I haven’t dug deep enough into the *individuals* involved with the actual glasswork.” The inspector raised an eyebrow. “You think one of them is our killer?” “Or knows something,” Milos corrected, his voice tight. “This glass isn't just a symbol to the Collector. It’s a message. A personal touch. Someone with intimate knowledge of these materials, this artistry.” He pointed to a name circled in red ink on his list. *Katarzyna Voronova*. “She was the lead conservator for the Grand Cathedral’s north rose window. Renowned, even then. Apparently, her work was… obsessive. Legend says she could identify a shard’s origin by feel alone.” “Voronova,” Zoryana repeated slowly. “As in, Grigoriy Belov’s wife? The oligarch? She’s a stained-glass restorer?” A flicker of surprise crossed her face. “The very same,” Milos confirmed, a cold certainty settling in his gut. The opulence of the Voronova estate, with its private chapel and workshop, suddenly seemed less like a gilded cage and more like a potential trove of secrets. His next move was clear. “I’m going to pay a visit to the Voronova Estate,” he declared, snapping his notebook shut. “I want to speak with their resident master restorer.”
