Rain poured down on the quiet, cobblestone street. A chilling wind whistled through the dark alleyways. The faint sound of a siren echoed in the distance. A figure slumped over in the shadows suddenly appeared. Curiosity piqued, a passerby slowly approached the body. Upon closer inspection, the grim truth was revealed. A single dagger protruded from the lifeless form. No identification or obvious clues were left behind. The opening scene was set for a perplexing mystery. Dread hung heavily in the damp, cold air tonight.
