A professional, high-end audiobook cover art, square 1024x1024 format. The central focus is a crystal champagne flute elegantly held by a woman's hand adorned with a vintage gold ring. Next to the glass, resting on a polished mahogany surface, lies a sleek, silver stiletto dagger with intricate, ornate engravings. The background is a moody, out-of-focus Art Deco lounge interior with soft golden light highlights and deep velvet shadows. The color palette consists of rich noir tones, deep emerald green, gold, and sparkling champagne silver. The aesthetic is sophisticated, mysterious, and cinematic, with a soft focus on the background to ensure a premium look. No text, no letters, no words, no title, no author name. Only visual artwork.
