  "prompt": "A moody, atmospheric illustration in the style of vintage noir film posters. The central image is a solitary, silhouetted figure of a man in a fedora and trench coat, standing at the end of a dimly lit, cobblestone alleyway. Shadows stretch long and distorted from unseen sources. A hint of a smoky, neon-lit city skyline is visible in the background, perhaps with a faint, stylized Art Deco building silhouette. The color palette is dominated by deep blues, grays, and blacks, with sharp, contrasting highlights of muted gold or amber from distant, indistinct lights. The overall mood should be one of suspense, mystery, and urban grit. The composition is centered on the figure, drawing the viewer's eye into the scene. Professional audiobook cover aesthetic, square 1024x1024 format. NO text, NO letters, NO words, NO title, NO author name.",
