Beautiful female private detective in a 1940s film noir setting. Tall and elegant with a slim, strong build, pale flawless skin, bold red lipstick, piercing eyes filled with suspicion. Wearing a tailored trench coat and fedora hat, short pencil skirt, and stockings. Standing under a flickering streetlamp in a rain-soaked alley, neon sign glowing faintly in the distance. Shadowy figures hinted in the background. Ultra-realistic retro noir art, highly detailed, cinematic chiaroscuro lighting, moody and mysterious atmosphere.
