黑白漫画中的旧港侦探

A single black-and-white hardboiled comic illustration of a 50-year-old detective in a raincoat standing under a harbor lamp, thick decisive ink shapes, restrained halftone shadows, wet dock ropes and distant cranes, diagonal 3:2 composition, no speech bubbles, captions or weapons.

单张黑白硬派漫画插画：50岁侦探穿雨衣站在港口灯下，粗而果断墨色块，克制半色调阴影、湿码头缆绳与远处吊机。斜向3:2，无对话泡、说明字或武器。
