  "prompt": "A square, professional audiobook cover art. The style should be dark, moody, and atmospheric, evoking psychological thriller and medical horror. The central image is a single, antique, tarnished silver scalpel lying on a cold, sterile, white marble slab. Subtle, dark shadows should stretch across the marble, hinting at unseen depths. The overall color palette is desaturated, dominated by deep grays, muted silvers, and stark whites, with perhaps a very faint, almost imperceptible hint of deep crimson emanating from a minuscule, unseen stain on the scalpel, suggesting past horrors. The lighting is dramatic and low-key, with a single, focused, cold light source casting sharp, elongated shadows. The composition should be clean and minimalist, emphasizing the starkness and the ominous presence of the scalpel. The mood is one of dread, precision, and underlying menace. No text, no letters, no words, no title, no author name.",
