The old mansion loomed, silhouetted against the dark sky. Rain lashed down, blurring the distorted windowpanes. A single light burned, a lonely beacon within. Inside, Lord Ashworth lay sprawled across the floor. His eyes stared vacantly, sightless, towards the ceiling. A crimson stain bloomed on his expensive velvet jacket. A ornate dagger rested nearby, glistening in the gloom. The air hung heavy, thick with untouched secrets. No sound could be heard, only the pelting rain. The stage was set for this tragic discovery.
