The clock struck twelve in the grand library, its chime echoing through the silent, dust-filled air of the manor house. A single crimson rose rested on the marble mantelpiece, its petals scattered like a silent accusation of the victim's guilt. Detectives examined the locked windows and the heavy oak door, finding no sign of forced entry whatsoever within the room. A cold draft seeped through the hidden panel behind the bookshelf, stirring the dust motes lazily in the dim light. The detective noticed a single strand of black hair on the victim's collar, glistening faintly under the chandelier's bright glow. No footprints marred the pristine floor except for a small, muddy heel print near the window which was slightly ajar.
