The island of Trachilos had no harbor deep enough for naval vessels, no airport, no strategic value that justified the concrete listening station built into its eastern cliff in 1967. NATO had paid for it, back when the Colonels ruled Greece and the Cold War was hot enough to scald. The station had monitored Soviet naval traffic in the Aegean, cataloged every submarine signature from Sevastopol to Tartus, built acoustic profiles that were still classified four decades later.

Unofficially, he was a pensioner the navy had forgotten to stop paying, a ghost in a ghost station, tolerated because acknowledging his existence would require paperwork no one wanted to file.

He spent the morning checking his equipment, ruling out the obvious explanations. Local interference from Turkish fishing boats—no, the signal had been too clear, too directional. Atmospheric ducting bouncing modern transmissions from hundreds of kilometers away—no, the content was impossible, the technical details accurate in ways that suggested intimate knowledge of submarine operations. A prank by some radio enthusiast with a grudge and research skills—possible, but the reference to 1994, to Michalis...
