Cold river damp clung to the stone pillars of St. Jude, turning the air inside the nave to a grey, freezing mist. Three elderly women, the last of the evening's sparse congregation, shuffled down the center aisle. Their heavy wool skirts dragged against the flagstones, whispering in the quiet church. I watched them from the steps of the chancel, my fingers resting on the cracked leather of the pulpit. One of them, old Mrs. Gable, paused at the heavy oak doors to pull her moth-eaten shawl tighter around her throat. She gave a slow, trembling nod toward the altar, her eyes cloudy with cataracts, before slipping out into the yellow fog. A massive iron latch clicked into place behind them with a definitive, heavy clack. Now, we were locked in. Yellow gaslight from the street lamps struggled to pierce the narrow stained-glass windows, casting long, distorted pools of amber across the nave. I reached into my cassock, my hand brushing the cold steel of Genesis where it lay nestled in my breast pocket. A sharp craving for the gin flask in my vestry desk hit me, dry and demanding. I ignored it, swallowing the bitter taste of stale tea instead. From the shadows of the south aisle, a low metallic clink broke the silence. St. Jude was a dying parish in a dying corner of London. Ordinary folk came here to pray for their souls, entirely unaware that the real battle for their lives was fought after the doors were locked. They believed in demons of spirit and flame. They did not know about the things of sinew and bone that crawled out of the river muck. Caleb was already at work. His lean figure moved with practiced efficiency, his faded red hair catching the dim candlelight as he bent over the side door. He was stretching thin copper bell-wires across the threshold, anchoring them to tiny brass bells he had salvaged from the old choir stalls. If the door was forced, even by an inch, the wire would snap and the bells would ring. Quietly, he worked without speaking, his gray eyes focused entirely on the knots. For three years, the boy had been my shadow, learning the quiet rhythms of this hidden war. He knew exactly what was coming. My thoughts drifted back to the leather-bound bestiary resting on my desk in the vestry. Handwritten notes in the margins, written by my predecessor, warned of its incomplete state. An unfinished beast was always more dangerous than a mature one. It was a creature born in pain, and it sought to inflict that pain on anything that moved. "That south door is braced with the thick oak beam," Caleb whispered, his voice low and steady. He rose from his knees, brushing dust from his dark servant's coat. "It will hold, but the wood is old." I nodded, my throat feeling like it was lined with sand. "And the vestry window?" I asked. "Secured," he replied, walking toward the sacristy. "That wire is tight enough to hum." Thick leather gloves lay on the sacristy table, their fingers stiffened by dried grease and alchemical residue. Caleb pulled them on, the heavy hide stretching over his knuckles with a dull creak. Next to him sat the Purifier. It was a brutal, industrial thing, a heavy brass cylinder that looked more at home in a steam-engine room than a house of God. Copper pipes spiraled around the main chamber, feeding into a long nozzle with a mechanical trigger. Inside the tank, several pints of holy acid sat under heavy pressure. This was the sacrament of Baptisms, the only weapon we had prepared tonight. We needed the acid to strip away the corrosive birth-slime that coated the immature Hound-class beast, exposing its soft, vulnerable hide to our silver rounds. Without it, Genesis's bullets would simply slide off the creature's back. Acid of this grade was a vile concoction. Caleb gripped the brass handle, lifting the heavy apparatus with a grunt. He turned a small valve near the pressure gauge. A sharp, wet hiss escaped the nozzle. Pungent vapor filled the small space of the chancel, smelling of burnt vinegar, sulfuric acid, and the bitter trace of alchemical salts. I coughed, the acidic fumes burning the back of my throat. "Pressure is holding well, Father," Caleb murmured, his voice muffled by his collar. "That nozzle is slightly stiff from the cold, though." "Work the lever," I told him, adjusting my cassock. "We cannot afford a jam. If that slime touches your skin, it will eat through the bone before you can scream." He nodded, his gloved fingers squeezing the trigger mechanism. A series of sharp, metallic clicks echoed through the dark nave. Each click felt like a clock ticking down the seconds to our demise. I walked back to the wooden lectern, my boots clicking against the cold stone floor. My fingers were trembling slightly, a symptom of the cold, or perhaps the lack of alcohol. Opening the Book of Common Prayer to the Night Office, I stared at the faded text. It was a ritual we always performed before a hunt. Not because I believed the words would magically protect us, but because the rhythm of the liturgy kept the terror from taking root. A man who fears is a man who hesitates, and a man who hesitates in our line of work is a dead man. "Let us pray," I muttered, my hoarse voice echoing off the high, dark rafters. Caleb stood near the altar steps, the heavy Purifier resting against his hip. In the flickering candlelight, he looked incredibly young, his face pale and his gray eyes wide. "He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty," I began. Those words sounded hollow in the empty church, bouncing off the cold stone pillars. "I will say of the Lord, He is my refuge and my fortress: my God; in him will I trust." Outside, the yellow fog seemed to press closer against the stained-glass windows, blotting out what little light remained of the city. A sudden, unnatural silence fell over the streets of Wapping. Distant rumbles of carriage wheels died away. Even the stray dogs that usually fought over scraps in the alleys behind St. Jude went completely silent. They knew. "Surely he shall deliver thee from the snare of the fowler, and from the noisome pestilence," I continued, my voice growing stronger. "He shall cover thee with his feathers, and under his wings shalt thou trust: his truth shall be thy shield and buckler." A draft swept through the chancel, causing the altar candles to flicker violently. Darkness warped across the stone walls, twisting into grotesque, monstrous shapes. "Thou shalt not be afraid for the terror by night; nor for the arrow that flieth by day," I read, my thumb tracing the worn edge of the page. I remembered the first time I had faced a Hound. That night, three of my brothers had been torn to ribbons before we realized that faith without lead was useless. Our Church had adapted since then, trade-marking its survival with steam, sulfur, and silver. We had traded our golden chalices for brass cylinders, our incense for acidic vapor. Yet, the words of the psalm remained our only shield against the madness. They were the only constant in a world that was slowly slipping into alchemical heresy. A massive impact shook the west door. *Thud.* That sound was deep and heavy, vibrating through the stone floor beneath my boots. Caleb’s head snapped toward the back of the nave, his knuckles turning white as he gripped the Purifier. "Father," he whispered, his voice trembling. "I hear something." "Nor for the pestilence that walketh in darkness; nor for the destruction that wasteth at noonday," I recited, refusing to look up from the book. My voice was dry, but it did not shake. "A thousand shall fall at thy side, and ten thousand at thy right hand; but it shall not come nigh thee." Another heavy blow struck the building, but this time it came from above. *Thud.* Old roof rafters groaned under a sudden, massive weight. Scraping claws dragged across the slate tiles, a dry, clicking movement that sounded like wrong joints snapping into place. It was moving toward the center of the roof, directly above where we stood. Caleb raised the heavy brass nozzle, aiming it at the dark beams overhead. "Only with thine eyes shalt thou behold and see the reward of the wicked," I read, my heart hammering against my ribs. Silence fell once more, heavy and suffocating. Candlelight flickered, casting long, trembling shadows that seemed to stretch toward the ceiling. Every breath felt like drawing in cold glass. I could hear the faint, wet dripping of water from a leaky pipe in the corner of the nave, each drop hitting the stone floor with a sharp, agonizing tap. The third thud struck the window above the south aisle, then silence. Caleb tightened his grip on the Purifier. I closed the book, my thumb still on the page. "It's coming."
