Captivating Book Cover for a Mystery Novel Titled "The Clockmaker’s

Create a captivating book cover for a mystery novel titled "The Clockmaker’s Secret," featuring steampunk-inspired metallic details such as ornate clock gears and aged, distressed textures. Place a glowing pocket watch with a subtly visible keyhole at its center as the main focal point. The backdrop should showcase a foggy cityscape with softly illuminated gas lamps and cobblestone streets to establish a shadowy, suspenseful vibe. Display the author’s name, "Eleanor Keene," in refined serif typography at the bottom. Use muted, earthy hues complemented by metallic bronze and gold highlights throughout the design. Position the book standing upright on a rustic wooden desk surrounded by scattered papers, an antique quill, and a magnifying glass to evoke a sense of exploration and mystery.
