A masterpiece illustration. A mysterious female agent in the style of Chris Riddell, a detailed ink illustration with fine lines, a seductive figure in a tight-fitting black latex suit, an open long raincoat dramatically fluttering, a woman holds a high collar of a raincoat with gloved hands, a mysterious face partially hidden under a wide-brimmed black hat, dark glasses reflect moonlight, expressive pose with a hip curve, a Gothic atmosphere with haze and shadows, carefully drawn details of costume and accessories, Riddel's signature hatching.
