  "prompt": "A professional audiobook cover, square 1024x1024 format. The artwork should evoke a sense of psychological thriller and suspense. The central image is a dimly lit, imposing Victorian-era house seen from a slightly low angle, partially shrouded in mist. Focus on the silhouette of the house with a few windows glowing with an eerie, flickering yellow light, suggesting a clandestine presence within. In the foreground, just outside the frame but implied to be present, a single, starkly lit, modern-style stethoscope rests on damp, dark earth, with a single, wilting red rose lying beside it. The color palette should be dominated by deep blues, charcoal grays, and muted purples, with sharp contrasts from the unsettling yellow light. The overall mood is one of isolation, mystery, and foreboding. The style should be photorealistic but with a painterly quality, creating a haunting and atmospheric aesthetic. No text, no letters, no words, no title, no author name.",
