Read Chapter 3: Watchman's Secret

The sea off Aegis was glass today, all honey-gold and turquoise, the kind of Mediterranean calm that made tourists believe the myths of benevolent gods. Élise floated on her back, arms spread wide, letting the water rock her like a cradle. Twenty meters below, the sunken city sprawled through the haze—columns and courtyards and the ghost of a forum, all waiting for the next excavation window. But not today. Today, she swam.

It was Antoine who had pushed her to take the afternoon off, in that careful, concerned way of his. *You’ve been chasing shadows for three days, Élise. The permits won’t move faster for your staring at them.* She'd laughed him off, then found herself in her swimsuit anyway, mask and fins in hand, because he was, infuriatingly, right.

She rolled onto her belly and kicked down, letting the thermocline wash over her skin. The light shifted from gold to green to a deep, dreaming blue. She wasn't hunting anything. That was the point. She was just *looking*, the way she had as a girl on the coast of Brittany, before the ocean had become a job, before every shadow on the sonar had to mean something.

The perimeter of the city proper was a mess of fallen masonry and silt dunes, a place the survey teams had flagged as low-priority rubble. She drifted over a collapsed archway, running her fingers along the pitted stone, feeling the rough kiss of a thousand years of encrustation. Then something caught her eye, a glint of metal, dulled and green, tucked into a shadowed ledge beneath the arch's keystone.

Not a coin. Not pottery. Something man-made, but wrong in a way she couldn't place. She finned closer, careful not to stir the silt. Her fingers closed around it, and the moment she touched it, she knew.

It was a diving watch. Heavy, steel-cased, with a cracked bezel and a face that had fogged over decades ago. The strap was a braided steel cord, rusted into a brittle fossil. She turned it over, and there, scratched deep into the caseback in a neat, engineer's hand, were words that made her heart stutter:

*For J.L., who saw the light.*

She surfaced a hundred meters from the boat, the watch clutched in her fist like a talisman. The sun was low enough to sting her eyes as she stripped off her mask, breathing hard. The inscription looped through her head, over and over. J.L. Who saw the light. Saw *what* light? The violet pulse of AEGIS-VII? The pale glimmer of a city that should have been swallowed by history?

*Don't jump,* she told herself. *Don't turn a trinket into a conspiracy.*

But she'd already pocketed it, and her hands were shaking.

---

Two hours later, she was in her cabin on the *Isabelle*, the watch laid out on a felt cloth under the work lamp. She'd photographed it, measured it, logged it. But the name bothered her. J.L. Common initials. Could be anyone. Could be a fisherman's son, a Navy diver, a salvage operator who'd lost his way.

She pulled up her laptop and compiled a list from the archives she'd seeded into the *Isabelle*'s server: French marine engineers, divers, and oceanographers who had gone missing or vanished from records between 1960 and 1975. The list was depressingly long—the Mediterranean ate people, always had. But she narrowed it by specialty, looking for anyone connected to seabed surveying, sonar work, or the kind of classified naval programs that didn't show up in public journals.

It took her forty minutes. The answer came from a clipped navy service record, scanned and barely legible, from a base at Toulon.

The name was Jacques Lemaire. Not the Lemaire she knew. A different one. Jacques Lemaire, *ingénieur en chef*, specializing in underwater acoustics and seabed penetration. Fitted for a standard-issue diving watch in 1962, which was noted, humorlessly, as "personnel equipment, non-standard issue." And then, in 1964, he had vanished. Not dead, not discharged. *Inconnu. Porté disparu.*

Disappeared in the line of duty. The file had a single red annotation: *Projet: VEILLEUR. Classé.*

*Watchman,* she whispered, and the hairs on her arm stood up. *Watchman.*

The color-coded citation pointed to a project code that shouldn't have existed. A French black program from the height of the Cold War, buried so deep that even her security clearance—her *good* security clearance, the one that had taken two years to earn—had never touched it.

She pulled up the rest of Lemaire's record. A photograph, grainy and overexposed. A man in his late thirties, high forehead, serious eyes, a pipe clamped between his teeth. The face of someone who had seen something he wasn't supposed to. And there, on his wrist, the same heavy steel watch. The same braided steel cord.

It was the only full photo in the file. The rest were low-res copies, front pages of internal newsletters, a grainy shot of a diving team on a barge, faces blacked out. She zoomed in on the last one, squinting.

Behind Lemaire, partially hidden by a crane, was a shape she knew with a jolt that sent ice through her veins.

A metallic teardrop. Sleek and smooth, the proportions off in a way that made your eye slide away. It was sitting on a flatbed trailer, lashed down with chains, and even in the half-light of the photograph, it seemed to hum with a weight the image couldn't quite carry.

The same shape as AEGIS-VII. The same impossible silhouette that had pulsed violet light into her face nine days ago.

She checked the date on the photo. 1963. A decade before the black program she'd traced had supposedly created AEGIS-VII. A decade before AEGIS-VII was *supposed* to exist.

"Merde," she breathed.

A knock at her door made her jump. She slammed the laptop shut, her heart hammering. "Yes?"

Antoine's voice filtered through, muffled and cautious. "Élise? You missed dinner. I brought you a plate. And the latest fuel report, if you want to be thrilled."

She stared at the watch, then at the closed laptop. For a moment, she was tempted to tell him everything—the watch, the inscription, the photo, the impossible predating of AEGIS-VII. Antoine's skepticism had been grinding, but it was *skepticism*, not dismissal like Leclerc's. Maybe it would temper her feverish certainty into something a sharper mind could verify.

But then she remembered the way Antoine had said *we work for Leclerc*, with that hint of darkness, of a leash she hadn't fully seen. And she remembered, with a colder clarity, how fast Marc Leclerc had written off the object on the deck.

"I'm fine," she called. "Just finishing a report. I'll come out in a minute."

There was a pause, heavy with unspoken hesitation. "The plate's outside when you're ready," Antoine said at last, and she heard his footsteps recede down the corridor.

She waited, counting his steps, until the sound died. Then she opened the laptop and stared at the photograph for a long, hard minute.

Jacques Lemaire had seen the light. And then he'd vanished.

She closed her eyes and pictured the map of the site. She knew every ridge, every trench, every patch of rubble that the survey teams had charted. But there was one place she'd never plotted. A place she'd swum over a dozen times, always dismissing it as a landslide scar.

A narrow gap in the rock, east of the sunken city's outer wall. A fissure that dropped away into blackness, too deep for the regular sonar sweeps to penetrate, too risky for a team that had a schedule to keep.

She opened her eyes and looked at the watch. At the inscription, the words engraved by someone who had loved Jacques Lemaire enough to give him a name that outlasted him.

*For J.L., who saw the light.*

Élise knew what he'd seen. The violet light. The impossible metal. The thing that had no business being under a Mediterranean city that had drowned two and a half thousand years ago.

And she knew, with a certainty that settled into her bones like cold water, that the fissure east of the wall was where the answer had gone to sleep.

She reached for her logbook, flipped to a fresh page, and wrote a single line:

*Tomorrow, I dive alone.*
