Read Chapter 4: The Watch

The building on Rue du Cygne smelled of boiled cabbage and old plaster. Élodie’s door was a cheap hollow-core thing with a deadbolt that took Julien less than a minute to pop with the pick set he never left home without. He slipped inside and shut the door behind him, listening to the hum of a refrigerator and the distant murmur of a television from the floor below.

The apartment was frozen in time. A half-drunk cup of coffee sat on the kitchen counter, its surface filmed with pale dust. A calendar on the wall still showed April 2019, and the day Élodie vanished was circled in red marker. Someone had taken care of the place—rent kept current, mail swept from the floor—but no one had touched a thing since she’d left for work that morning.

Julien’s boots tracked dark prints across the laminate floor. He pulled on nitrile gloves, the same careful discipline he used in the catacombs, and moved through the rooms with an explorer’s eye. Bedroom: floral quilt, laundry basket empty, a stack of library books on the nightstand. He checked the closet first—a tangle of coats and dresses, shoes in neat rows.

He was about to turn away when he noticed the floorboards. Just inside the closet, one plank was a shade darker than the others, and the seams around it were too uniform. Nail heads glinted where they repeated at odd intervals. He knelt, ran his fingers along the edge of the plank, and found a recessed catch disguised as a knot in the wood.

It clicked open.

A narrow stairwell descended into darkness, the steps steep and uncarpeted. Cold air breathed up from below, carrying the faint mineral smell of limestone and moisture. Julien paused. This was the kind of threshold he’d crossed a hundred times in other people’s houses, and it always ended the same way—nothing. But something about the chill of that air felt familiar. It was the same cold that had come off the spectral boulevard he’d found beneath the ossuary.

He swept his phone light over the steps and went down.

The cellar was a single long room, low-ceilinged, walls of rough stone that dripped in one corner. But it wasn’t a standard basement. The walls had been lined with cork board, and on the cork board were pinned maps. Dozens of them. Some were printed, others hand-drawn on tracing paper with the obsessive precision of a cartographer working from memory. Julien moved closer, his breath fogging in the cold.

These weren’t street maps. They were maps of the underground.

He recognized the official network—the catacomb galleries marked in red ink, the Métro tunnels in blue. But beyond that, in pencil and sometimes in charcoal, were lines that didn’t appear on any municipal record. Branches that dead-ended into solid rock on paper became full networks here. He saw the ossuary he’d found two nights ago, and beyond it, drawn in a stippled shading that made his skin prickle, the long straight avenue of what could only be the phantom boulevard. Someone had labeled it in neat block letters: *RUE DE L’OUBLI*. The Street of Forgetting.

His thumb hovered over the label. *Rue de l’Oubli.* The name felt like a warning.

The maps were annotated in a small, tight hand, filled with dates and measurements and cryptic symbols. Some of the notes were in French, some in what looked like creole, a few in symbols he didn’t recognize. At the bottom of the room, shoved against the far wall, was a wooden table with a chair. On the table sat a locked box.

Julien’s breath caught.

The box was made of walnut, the same shade and grain as the one his father had kept on his desk growing up—the one that had held his mother’s letters, his own first drawings. He’d been told after the funeral that the box had been sold with the rest of his father’s belongings.

But here it was. He picked it up. The lock was a simple disc mechanism, and he worked it with a feeler pick and a steady hand. It took him under a minute. He lifted the lid.

Inside, nestled on a bed of faded felt, lay his father’s pocket watch.

He had to run his thumb over the engraving twice before he believed it. *A.M. — Toujours ensemble.* Always together. A gift from his mother on their tenth anniversary. Julien remembered his father winding it every night before bed, the precise ritual of it, the click of the crown, the soft ticking that used to lull him to sleep through the thin walls of their old apartment on Rue de la Roquette.

The watch had stopped working years before his father died. But it hadn’t been lost then. It had sat in its wooden box on the shelf above his father’s workbench.

And now it sat in the palm of his gloved hand, in the locked basement of a missing woman’s apartment, in a room full of maps that charted routes to a place that didn’t exist.

Julien turned the watch over, and his thumb found a hairline crack in the crystal. He’d never noticed that before. What he noticed now, pressing slightly, was that the case had a seam that resisted. He worked the crystal housing with his nails until the face swung open on a tiny hinge.

Inside, where the watch mechanism should have been, was a strip of paper, rolled tight and yellowed at the edges.

He unrolled it. Handwriting, cramped and hurried, faded with age but unmistakable. His father’s hand. He’d know the shape of those letters anywhere.

*J—if you’re reading this, I was wrong to hide it from you. The vein runs true under Les Halles. Forty meters below the fountain. The archive is there. I found the door. I could not open it. The key is memory. Do not go alone. They collect.*

The paper ended mid-sentence. The ink smeared at the bottom as though the writer had been interrupted, or had stopped himself. Julien read the lines three times, his pulse hammering in his throat.

His father had been here. In Élodie’s apartment, or in this room, or both. He’d known about the phantom underground, a full lifetime before Julien stumbled into it through a hole in a forgotten ossuary wall. He’d mapped it. He’d tried to find a door beneath the fountain at Les Halles, forty meters down, a door that required something called a key. And he’d hidden this note in a watch he’d given to the world as lost.

Julien pocketed the watch, then the note. He took a slow breath, the air of the cellar thick with limestone dust and time.

His phone buzzed in his jacket pocket. He pulled it out. Mireille’s name on the screen.

**Ping me when you get this. I put together the timeline on our missing friend. The usual stuff until the last week—then she goes dark for three days before she vanishes. But here’s the weird bit: the last ping from her phone wasn’t at Les Halles. It was at a spot under the 20th. I’m sending coordinates. Looks like a service tunnel junction near the old lime-kiln shafts.**

Julien stared at the message. The same junction Claire’s maps had marked for him, he realized, the one leading toward Porte des Lilas. The coincidence was too heavy to be coincidence.

The last word in his father’s note echoed in his skull.

*They collect.*

He looked back at the maps. Somewhere in the static of scrawled pencil lines, his father had been mapping something more than geology. He’d been mapping a threat. And Élodie had been touching that same nerve when she disappeared.

He climbed back up the stairwell, closed the closet door behind him, and stood in the stillness of Élodie’s dead apartment. Seven years of unanswered questions pressed in from every wall.

His father had been here. And his father had been afraid of whatever was down there. That was the thought that settled worst of all—because Julien had never, not once, seen his father afraid of anything.

He pulled out his phone and typed a quick reply to Mireille.

**Study the junctions. I’m on my way.**

Before he hit send, he added another line.

**Also—do you know anyone who can tell me the difference between a collector and a memory?**

He pocketed the phone and stepped out into the dusk of the 1st arrondissement, the old watch ticking against his hip. It wasn’t ticking. It was broken. He could feel the cold weight of it through the fabric regardless, like a heart that refused to stop beating even after the blood had run dry.
