Photorealistic Detective in a Castle Courtyard

Photorealistic scene of a hard-boiled detective in a long dark trench coat and fedora, standing in a damp medieval castle courtyard at dusk. He holds a notebook in one gloved hand and a flashlight in the other, surveying mossy stone arches, ivy-clad walls, and a carved fountain. Warm torchlight reflecting on wet cobblestones mingles with cool moonlight, mist swirling around his boots. Cinematic, ultra-realistic textures: damp stone, leather, fabric, skin; shallow depth of field, 85mm lens, 4K quality, film grain, dramatic shadows, moody blue-green palette.
