  "prompt": "A moody, atmospheric image evoking the genre of espionage and moral ambiguity. Imagine a narrow, rain-slicked cobblestone alleyway at dusk in a vaguely European city. A lone figure, their back to the viewer, is partially obscured by the shadow of a grand, old building. They wear a trench coat, collar turned up. A single, faint, warm light spills from a distant doorway, casting long, distorted shadows. The overall color palette is muted, dominated by deep blues, grays, and hints of sepia, with a subtle, almost imperceptible film grain texture. The composition is tight, creating a sense of isolation and unease. The mood is tense, mysterious, and introspective, suggesting hidden dangers and unspoken secrets. Professional audiobook cover aesthetic, square 1024x1024 format. NO text, NO letters, NO words, NO title, NO author name — only visual artwork.",
