  "prompt": "A square 1024x1024 professional audiobook cover, digital painting in a dark, gritty, realistic style. The primary imagery is a shadowy figure, hunched and indistinct, partially obscured by the pouring rain and the dim, yellow glow of a distant, blurry streetlamp. Their silhouette suggests a trench coat. The background is a blurred, wet, cobblestone street in a European city, with faint architectural details hinting at old brick buildings. The overall mood is one of paranoia, isolation, and hidden danger. The color palette is dominated by deep blues, grays, and muted yellows, with stark contrasts between light and shadow. The composition should be tight, focusing on the solitary figure and the oppressive atmosphere. No text, no letters, no words, no title, no author name.",
