  "prompt": "A dark and atmospheric book cover, square 1024x1024 format. The central image is a shadowy figure in a classic fedora hat, seen from behind, standing at the edge of a dimly lit, fog-shrouded cobblestone street. The street is lined with old, ornate buildings with darkened windows, suggesting a vintage European city. A single, vintage gas lamp casts a pool of golden, diffused light on the wet cobblestones, creating long, distorted shadows. The overall color palette is muted, dominated by deep blues, grays, and blacks, with warm, selective accents of the gas lamp's glow and perhaps a faint, distant red glow from a single window. The mood is mysterious, suspenseful, and slightly noir. The composition should be dramatic, with the figure slightly off-center, drawing the viewer's eye into the scene. The style should be painterly but with a sharp focus on detail and texture, evoking a sense of classic mystery thriller art. No text elements whatsoever.",
