"You're late, Gereon," a voice whispered from the back row. It was Charlotte Ritter, her eyes bright even in the dim light. She nodded toward the screen. "The film is a front. The subtitles aren't translating the actors; they're translating the coordinates for the Sorokin gold."

Gereon Rath adjusted his damp hat as the heavy mist of a 1929 Berlin evening rolled over the Spree. He wasn’t looking for trouble tonight—he was looking for a ghost. In his pocket, he clutched a crumpled lead: a name whispered in the shadows of the Moka Efti, scrawled on a napkin that read simply, “Złota Praga.”

Gereon watched as a line of Polish text appeared: Prawda leży pod brukiem (The truth lies beneath the pavement).

He ducked into a cramped, flickering cinema in the Wedding district. The air was thick with the scent of cheap tobacco and damp wool. On the screen, a silent film flickered, but the dialogue wasn't in the familiar German Gothic script. Below the moving shadows, white text danced across the frame—.

Suddenly, the projector jammed. The film melted into a white blur, leaving only the last line of the subtitles burned into Gereon's mind. He didn't need a translator to know what came next. In the chaos of the Weimar Republic, everyone spoke the language of betrayal.
