The rain drummed against the cobblestones as Detective Hart stepped into the dimly lit alleyway. A single streetlamp flickered, casting long shadows that danced like restless spirits in the night. The body lay sprawled near the dumpster, arms outstretched as if reaching for something just beyond grasp. A pool of crimson spread slowly, seeping into the cracks of the weathered pavement beneath. Hart knelt, his gloved fingers brushing the victim’s cold cheek, searching for any sign of life. The victim’s eyes stared blankly upward, frozen in an expression of shock and terror. A silver locket glinted in the dim light, half-hidden beneath the victim’s torn blouse. Hart carefully pried it open, revealing a faded photograph of a smiling couple. The detective’s pulse quickened as he recognized the man in the picture—his own missing partner. A distant siren wailed, growing louder as the first patrol car screeched to a halt. Hart stood, his mind racing with questions, each one darker than the last. The alley seemed to close in around him, the walls whispering secrets he wasn’t sure he wanted to hear. Somewhere in the shadows, a killer watched, waiting for the perfect moment to strike again.
