月明かりの湖畔と黄色いアヒルのおもちゃと女性探偵

A beautiful adult female detective standing alone beside a dark, silent lake in the middle of the night, investigating something mysterious. She has elegant blonde hair tied in a refined updo bun, soft but serious gray eyes, and a calm, intelligent expression that conveys experience, emotional restraint, and determination. She wears her established elegant detective outfit: a refined dark-red detective coat over a crisp white blouse, fitted black trousers, practical black boots, and a professional belt carrying her investigation equipment. She holds a flashlight in one hand, illuminating the surface of the lake. A thin layer of pale mist drifts across the water and around her feet. The lake is almost perfectly still, reflecting fragments of the moonlight. The flashlight beam reveals a small, ordinary yellow rubber duck floating alone on the dark water. The detective looks directly at it with a subtle expression of confusion, as if thinking, “It’s just a rubber duck…” She does not yet understand its significance. The composition should make the rubber duck appear small and innocent compared with the vast, mysterious environment. Keep the detective as the main focus while making the duck clearly visible inside the flashlight beam. Above the lake is a large full moon partially surrounded by slow-moving clouds, silently watching over the entire scene, creating a mysterious and slightly melancholic atmosphere. The moon should feel like a silent witness rather than an evil object. Subtle supernatural uneasiness: the duck has no red eyes and appears completely normal, but its reflection in the water is slightly unnatural, creating the faint impression that it is looking directly toward the detective. Keep this detail extremely subtle and ambiguous.
