The rain hammered loudly on the abandoned mansion's fractured, broken roof. A lone figure lurked silently beneath the gnarled, twisting oak branches. Inside, shadows danced across walls stained with time's dark memories. A scream shattered the night, echoing through the fog-covered empty street. Detective Monroe arrived, eyes sharp, searching for answers beneath dim light. A bloodstained dagger lay concealed beneath the crimson velvet curtain nearby. Whispers of secrets long buried echoed softly in the shadowed, aged halls. An old, leather-bound journal was found resting atop dusty bookshelves. Mystery hung heavy as fog, cloaking the secrets of this night. Every clue pointed toward darkness hiding beneath centuries of silent suspicion.
