Mysterious woman, 1920s style, Sonja Greene Lovecraft, elegant posture, vintage glasses, curly brown hair, subtle makeup, slender chest, fitted waist, long legs, flowing black dress, lace gloves, pearl necklace, holding a leather-bound book, sitting in a dimly lit, ornate study, surrounded by shelves of ancient tomes, mysterious artifacts, and eerie taxidermy, with a faint hint of misty fog outside the window, soft candlelight, cinematic composition, film grain, nostalgic atmosphere.
