  "prompt": "A square, 1024x1024, professional audiobook cover art. The style is classic mystery illustration with a hint of vintage. Dominating the center is an antique, ornate pocket watch lying open, its gears subtly visible, suggesting the passage of time and the intricate nature of the mystery. Around the watch, scattered or partially obscured, are symbolic elements: a single, delicate feather hinting at a fragile clue, a tarnished silver locket with a faint, ghostly reflection, and a few crumpled, old letters with elegant, indecipherable script. The background is a deep, moody charcoal grey, with soft, diffused light emanating from behind the watch, casting subtle, dramatic shadows. The overall mood is one of intrigue, melancholy, and hidden secrets. The color palette is limited to deep grays, muted silver, antique gold for the watch's inner workings, and a hint of sepia for the letters. The composition is balanced and atmospheric, drawing the viewer's eye to the central elements without being cluttered. Professional, high-quality rendering.",
