Chapter 1: Signal in the Rain
A rainy night in Old Brussels. The cobblestones gleamed with moisture, and the streetlamps sliced the falling rain into a million silver needles. Gregory stood outside St. Hubert's Arcade, a brown paper bag tucked under his arm and a yellowed archival page pinched between his fingers. This was the third time this year he’d been sorting through the family’s old relics. His breathing was shallow and his palms were shaking, though he forced himself to stay still.
An argument drifted out from the arcade—French, with a hint of a Flemish accent. He instinctively leaned in to listen, and suddenly, a piercing frequency stabbed into his eardrums.
It sounded like an electric current, like metal scraping against metal from a great height. A normal person wouldn't have heard it. But Gregory did. Beneath the surface of the shouting lay a lower frequency—muffled, urgent, like someone had wrapped their anxiety in duct tape. He frowned, his feet moving toward the café of their own accord. The smell of coffee mixed with cigarette smoke wafted out, and condensation clung to the glass doors.
He pushed inside, his eyes scanning the long tables. A man in a grey trench coat was leaning down, whispering to a gaunt man opposite him, occasionally sliding an envelope across the table.
Gregory stood by the bar, his grip tightening on the paper bag. The arguing stopped abruptly; the only sound left in the café was the light clink of cups and saucers. He walked over slowly and took a seat diagonally across from the man in grey. Two black coffees sat on the table; one had already gone cold.
