The Frequency of the Dead – Chapter 15
Kerosene and Old Photographs
She went to Casimir Lund’s apartment again. The police seal had been removed — the case was closed, cardiac arrest, routine. No one was guarding it. The landlord had not yet cleared it; there was a small card pinned to the door listing an estate agent’s number, but the flat was otherwise undisturbed.
She had brought tools this time. A spectrum analyzer, small enough to fit in a bag. She went to the Grundig and ran the analyzer across its circuitry. The radio was still on — she had not been back since the first visit, but it was still playing the signal, as Petra’s text had noted it was, as her own measurements had confirmed. She ran the analyzer and found, as she suspected, that the Grundig itself had been modified. There was a secondary transmitter board inside it, connected to the main circuit, that was not part of the original Grundig design. Casimir had built it in himself. The radio was not simply receiving the signal. It was retransmitting it.
The signal was coming from somewhere and being rebroadcast from the apartment. Casimir had turned his own home into a relay node — a legitimate one, inside the surveillance network’s architecture, one that Thorn’s people would recognize but could not shut down without admitting they’d detected it, which would require admitting they knew the signal existed.
It was, Mira thought, the work of a man who had been an engineer for thirty years and who had understood, at the end, that the most elegant solutions are the ones that use the enemy’s own architecture against them.
She found the photographs behind a false panel in the bookshelf — she found the panel because the technical manuals on the shelf were arranged in a pattern she recognized as deliberate: their call numbers formed a sequence that resolved, when she applied the same encoding as the signal, to a three-digit combination. Behind the panel: a bundle of photographs, wrapped in oilcloth against the apartment’s humidity, and beneath them, a USB drive.
The photographs showed the relay station — both the city location and three others she didn’t recognize. They showed equipment, installation dates written in marker on the walls, cable routes, access codes. They showed, in one photograph, two men standing in front of a rack of servers: one of them she recognized from the NTA records as a younger Arvid Thorn. The other was a man she’d not seen before — older, with the bearing of someone who had spent their life knowing they were the most important person in the room.
Vilhelm Ost.
She was looking at a photograph of a man the world believed was dead and who had, eighteen hours ago, sent her a letter signed with his initials. She put the photographs in her bag. She plugged the USB drive into a clean laptop she’d bought specifically for this purpose and found, on it, the decryption key Rook had described. Not the key itself — but a partial key, and instructions for recovering the rest from the relay station.
There was also a voice message file. She put in earphones and played it. Casimir Lund’s voice — older, slow with effort, but steady: “If you’ve found this, you’ve already understood most of it. The rest is at the relay station. You have until day eleven, which is the day Thorn runs the automated purge — a safety cycle, in case of discovery. After that the decryption key is destroyed and the archive is locked permanently. I’m sorry I couldn’t do this myself. I ran out of time. Thank you, whoever you are, for being curious enough.”
