Read Chapter 1: The Moving Stone

The scaffolding groaned under Luc Moreau’s weight as he shifted, a sound he’d long since stopped hearing. Five years on this Saint-Eustache job, and the old church’s complaints were as familiar as his own breathing. He ran a gloved finger along the ridge of a limestone crocket, feeling for the hairline fractures that betrayed water damage or stress. The stone was quiet today. Good.

He was mid-way up the north tower, repairing a section of balustrade that had crumbled after the last hard frost. The morning light was pale and thin, filtering through the haze of Paris traffic below, and the city hummed its usual grey murmur. Luc preferred it up here. Down there, people rushed past masterpieces without a glance. Up here, the stone asked for patience, and Luc gave it willingly.

His phone buzzed in his pocket. He ignored it. Probably the site supervisor again, asking about the delivery of the new blocks. The delivery was late. The delivery was always late.

He worked for another hour, chiseling away the degraded mortar and fitting a new piece of limestone into place. The fit was almost perfect—a trace of lightness in the corner that he’d have to shim with a sliver of slate. He was about to mark it when something caught his eye.

Across the tower’s inner parapet, perched on the balustrade like a miser counting his coins, sat a small gargoyle. One of a pair, they flanked the south-facing corner—a leering ape-like creature and a snarling dog. Luc had studied them both, catalogued their damage, laughed at their cartoonish ugliness. The dog was on the left. The ape was on the right.

Now the dog was on the right.

Luc blinked, squinted, and set down his chisel. He wiped his brow with the back of his hand, then looked again. No, not the dog. The ape. The ape was on the left. The dog on the right. They had swapped positions.

He stared for a full ten seconds, waiting for his mind to correct itself, for the trick of the light or a lazy squint to resolve the image into what it should be.

It didn’t.

Luc climbed down the inner ladder and walked around the parapet to the corner. The two gargoyles stood exactly as he’d seen them—dog on the right, ape on the left. They had always been this way, hadn’t they? He’d photographed them a hundred times. The dog, with its ears pinned back and its lip curled, was undoubtedly the one that crowded the corner on the left when viewed from below. He’d noted its missing tooth, the same one now visible on the right.

He reached out a hand and touched the ape’s face. Cold stone. Rough patina. He might have imagined the swap; a long morning, an empty stomach. But he hadn’t imagined it. His memory was a working tool, as precise as his calipers.

He checked the bases. No fresh masonry dust. No tool marks. The stones were seated in their bedding as if they’d never moved.

Luc laughed at himself—a short, dry sound. “You’re seeing things, Moreau. Sun’s getting to your head.”

But it was barely nine in the morning, and the sky was overcast.

He shook it off, climbed back to his balustrade, and finished his work in a mood of quiet irritation. By noon he had sealed the new block and was clearing away his tools. The gargoyles were still as he’d found them: dog on the right, ape on the left. Fine. Whatever. A trick of the light.

He took a long lunch in a café across the street, ate a croque-monsieur without tasting it, and tried to lose himself in the afternoon’s paper. He read the same paragraph three times, but his thoughts kept returning to the tower. There was a logic to stones. They didn’t move. They couldn’t move. That was the whole point of them.

By the time he returned to the site, the sun had broken through and painted the church’s façade a warm buttery gold. He climbed the scaffolding again, his muscles on autopilot, and finished the day’s repairs with mechanical efficiency. He avoided looking at the corner until he was packing his bag at dusk.

He had to look.

The dog was back on the left. The ape on the right.

Luc felt the skin on his neck prickle. He stood very still, his bag half-zipped, his eyes locked on the paired gargoyles. They were stone. They were ancient. They were exactly where they’d been in every photograph he’d ever taken. But something had moved. Something had changed, and he couldn't explain it.

A cold draft circled his ankles, smelling faintly of damp mortar and something else—a sharp, mineral tang, like copper left in the rain. He zipped his bag with a jerk and made his way down the scaffolding, not looking back, though every instinct screamed at him to run.

The church was quiet as he reached the ground. The street lamps had begun to flicker on, and the evening traffic had thickened to a crawl. Luc crossed the parvis, his footsteps quick, and fished out his keys to the workshop. He had a small shared space in the Marais, a converted carpenter’s atelier where his mentor, François, kept the bulk of his archives and tools.

He was halfway to the Metro when he stopped. The sound was faint at first, barely a whisper against the general drone of the city. But it reached him clearly, threading through the muffled roar of buses and the murmur of pedestrians: a scraping, unhurried sound. Stone grinding against stone.

It came from inside the church’s walls.

Luc turned. The night had grown thick around the towers, and the floodlights had not yet clicked on, leaving Saint-Eustache a dark hulking mass against the purple sky. He strained his ears, felt the sound again—a dry, sliding rasp, as if someone were dragging a slab across a floor above his head.

The hairs on his arms stood up.

He took a hesitant step back toward the church, then stopped himself. What would he do? Knock on the door and tell the rector that he'd seen a gargoyle move and heard scraping in the walls? He'd be laughed out of the parish. He wasn't a superstitious man. He was a craftsman. Stones were static; he knew their weights, their faults, their demands.

The scraping stopped.

Then it began again, closer. Inside the north tower’s base, just behind the heavy oak door that led to the bell tower stairs.

Luc backed away slowly, his heart hammering against his ribs. His rational mind was assembling arguments: the scraping could be a boiler pipe expanding, a rat in the walls, the building’s ancient frame shifting in the evening cold. All perfectly reasonable. All utterly unconvincing.

He reached the street corner before he turned and ran. His bag slapped against his hip, his boots rang on the pavement, and he didn’t stop running until he burst into the bustling safety of the Rue Montorgueil, where the bars were full and the lights were bright and nothing could scrape its way through the noise of living souls.

He leaned against a butcher’s shutter, chest heaving. A waiter passing by gave him a curious look. Luc waved him off, forcing his breathing to slow.

He looked down at his hands. They were steady now. Good. He was a professional. He would go home, drink a glass of wine, and sleep. In the morning, the gargoyles would be in their right places, and the scraping would be a mystery he could forget.

But as he walked the rest of the way to his flat, a small voice in his head—a voice with the whisper of ancient mortar—told him he was a fool.

The stone had moved.

And it had wanted him to see it.
