Under the pale moonlight, an eerie silence draped over the ancient manor, concealing the sinister truth unfolding within its walls ominously. A shroud of mist crept through the garden, wrapping around the sprawling roots of the oak tree, where secrets whispered and dangers lurked unseen. In the study, a fire crackled, illuminating the aged mahogany desk, upon which a bloody dagger lay next to a single, old-fashioned key. Suddenly, a muffled scream pierced the tranquil night, echoing through the corridors, alerting the guests that something was horrifically amiss now. Draped in shadows, a figure emerged from the library, their heart pounding in terror, realizing the mansion held a dark chapter yet unknown.
