A single-frame anime still from a classic mystery series, rendered in a vintage 90s cel-shaded style with muted earth tones and heavy ink outlines. Interior medium shot of a dimly lit Victorian-style detective study: the detective, a slender adult man with wire-rimmed glasses and a dark overcoat draped on his shoulders, leans over a mahogany desk covered in pinned photographs, red string, and a brass magnifying glass. A single desk lamp casts a warm amber pool of light. Bookshelves tower floor-to-ceiling with leather-bound volumes. A large corkboard behind him is plastered with crime-scene photographs connected by red thread. Through a rain-streaked sash window, dark rooftops glow faintly under gaslamp orange. An aged parchment nameplate on the desk reads "Karasu Shinjiro -- Detective" in neat printed text. Color palette: amber, dark walnut, ivory, shadow grey, crimson thread.
