  "prompt": "A dramatic and moody audiobook cover illustration for a classic mystery novel. The central image is a dimly lit, grand Victorian-era mansion seen from a low angle at twilight. Thick, swirling fog partially obscures the lower floors, creating an eerie and mysterious atmosphere. Silhouetted against a single illuminated window on the upper floor, a faint, spectral human figure can be seen. Ancient, gnarled trees with bare branches frame the scene, adding to the gothic feel. The color palette is dominated by deep blues, charcoal grays, and muted purples, with the only light source being a warm, amber glow from the distant window and a hint of an overcast, stormy sky. The overall composition should be symmetrical and foreboding, evoking suspense and a sense of hidden danger. Square 1024x1024 format, high detail, painterly style, no text, no logos, no letters.",
