The Punic seal wasn't just a clue; it was a lockpick. For three days, Thorne's team, now expanded to include a quiet unit from Specialist Crime, scoured databases of private vault companies, high-security storage facilities, and exclusive banks in London. They looked for any link to Rowe, his Aethelred Foundation, or the aliases of his known associates.
The break came from an unexpected source: the embossed card Rowe had given Elara. The symbol of the key, under digital magnification, revealed microscopic striations—a sort of fingerprint. It matched the security engraving on the access cards for The Charter Vaults, a members-only storage facility buried deep beneath a building in the City of London, so discreet it had no sign.
"It's the Fort Knox for secrets," the tech agent explained. "Art, bullion, documents, blackmail material. Access requires a physical key and a biometric scan. No records of contents. Total anonymity."
"And Rowe has a box there," Thorne concluded.
"We can't get a warrant based on a symbol on a card and a hunch," the Detective Superintendent overseeing the operation warned. "We need probable cause inside the facility."
Elara studied the high-resolution image of the seal. The 'keyhole' in the 'M'. "What if the key isn't for the main door? What if it's for the individual box? The seal is the impression the key makes in the box's wax or soft metal lock. Each client's key would be unique. If we could find the key itself..."
"Petrov has it," Thorne said. "She stole it. She's not going to hand it over."
"Maybe she already has," Elara countered. "In her own way." She recalled Petrov's note: 'The key to the first lock.' And the first murder, the first "lock" in Sandys's series, was the museum killing, linked to the Roman pugio. The dagger Finch had authenticated. The dagger sourced through Rowe's foundation.
"What if the 'box' isn't at the Charter Vaults? What if it's the source? The original container for the artifacts? A crate, a cabinet, a chest that Rowe used to store his acquisitions before they were distributed?"
They went back to the crime scene photos from the salt mine. The objects had been laid out on a table, but they'd been transported in modern, sturdy crates. Standardized. Untraceable.
But the first object, the one that started it all—the pugio—had a different provenance. It came from the British Museum, via Finch. It would have been transported with extreme care. In something custom.
Elara went back to the Museum's internal logs for the deaccession of the dagger. The paperwork listed the transport company: Atlas Secure Logistics. A subsidiary, upon digging, of a holding company that was a client of The Charter Vaults.
It was a thread, gossamer-thin.
They couldn't raid the Vaults. But they could interview—pressure—Atlas Logistics. Under threat of prosecution for handling stolen cultural property, the manager admitted that for "special items" for "Mr. Rowe's foundation," they used a specific, reinforced antique chest, sourced by the client. A 16th-century Italian cassone, a marriage chest. It was ornately carved, and its large lock was a unique, non-reproducible mechanism.
"A chest," Elara said, the final piece snapping into place. "The 'box.' It's not in the vault. It's the transport container itself. Rowe uses it to move high-value items. Petrov would have had access to it. She could have taken the key, or made an impression of it."
"So where's the chest now?" Thorne asked the manager.
The man consulted his log, sweating. "It was checked out for a transfer... three days ago. To the Buckland Auction House. For a pre-sale inspection of a consignment from the Aethelred Foundation."
Rowe was liquidating. Moving the collection, or part of it, into the legitimate auction market, laundering it through a reputable house. The chest would be there, with its contents.
They moved fast. Buckland's was a fortress of old-world manners and cutting-edge security. Thorne arrived with a warrant, not for the auction items, but to seize the cassone as "potential evidence used in the conveyance of artifacts linked to crimes."
The head of Buckland's, a Sir James something-or-other, was apoplectic but cornered. The chest was in a basement viewing room.
It was a monstrous, beautiful thing—dark oak, carved with scenes of the Rape of the Sabine Women (a fittingly violent allegory). Its large, iron lock plate was central. And pressed into a small slab of sealing wax still clinging to the metal was a perfect, fresh impression.
The impression of the Punic seal.
Petrov had been here. She had sealed the chest after taking something, or putting something in. A message in wax.
They carefully opened the chest. Inside, nestled in custom foam, were not artifacts, but files. Dossiers. Photographs. Financial records. It was Rowe's blackmail archive. Dirt on his wealthy clients, compromising details on corrupt officials who smoothed his acquisitions, records of every illicit transaction and every person who had ever helped him.
Petrov hadn't just stolen a key. She had emptied his most valuable vault and delivered it to them, using the chest as the Trojan horse. Her "reciprocity." She had given them the means to destroy Silas Rowe utterly.
And sitting on top of the files was a single, new object. A small, modern USB drive. On it, a single file labelled: "Protocol Carthage – Final Audit."
Elara plugged it into a secure laptop. It was a ledger, but not of money. It was a list of names, dates, locations. It detailed every artifact Rowe's network had ever moved, every historical crime that had inspired Sandys and Moreau, and—most chillingly—a column titled "Potential Future Applications." It listed modern sites, corporations, individuals deemed "historically corrupt" by the network's ideology. It was a hit list. A curriculum for the next generation.
And at the very bottom, a new entry, added days ago:
"Subject: The Library Itself. Target: Aethelred Foundation/Charter Vaults Nexus. Rationale: To prevent re-containment, mummification of the truth. Action: Data liberation & structural compromise. Agent: Custos Salis. Status: Initiated."
Petrov wasn't just destroying Rowe. She was planning to burn the library down. And she had just handed them the floor plans and the matches.
Thorne looked at the screen, then at the chest of damning evidence. "She's not grooming you, Elara. She's promoting you. She's making you the executor of Rowe's will. She's giving you everything you need to end him, so she can be free to pursue her own work, unencumbered by the old guard."
Elara stared at the words "structural compromise." Petrov wasn't going to auction artifacts. She was going to turn the entire network—its records, its finances, its secrets—into a public spectacle. A final, devastating "publication" of the Ariadne Codex's modern chapter.
They had the evidence to cage the librarian. But the conservator was already in the next room, preparing to blow the whole museum to hell.
