A hard-boiled detective stands under the flickering streetlamp, rain-soaked pavement reflecting the vibrant hues of neon signs. Clad in a fedora and trench coat, he puffs on a cigarette, eyes scanning the dimly lit alleyways. Wisps of smoke curl into the air, merging with the mystery shrouding the city. In the distance, the faint sound of jazz plays, mingling with the heartbeat of a metropolis teetering on the edge of danger.
