The rain fell steadily on the cobblestone streets of the ancient village as the detective approached the crimson old manor. A single lantern flickered weakly in the deep darkness near the tall iron gates that stood very slightly ajar tonight. Inside the grand hallway, shadows danced across the cold marble floor where fresh crimson drops stained those white stone tiles. The detective knelt carefully beside the lifeless body and noticed one strange silver key lying on the dark floor nearby. A heavy silence filled the air as the detective slowly examined the mysterious note pinned to the victim's cold chest.
