The rain pounded softly against the old manor’s dark stone walls. Inside, Detective Laura arrived, her coat dripping from the storm’s fury. The butler whispered hurriedly, eyes wide with unspoken, hidden fears. In the grand hall, a body sprawled, blood staining polished marble floors. Candles flickered weakly, casting eerie shadows on the painting faces. A shattered vase lay nearby, fragments scattered like spilled secrets. Heavy silence enveloped the room, broken only by whispered nervous breaths. Detective Laura examined the scene, searching for clues and motives. A torn letter clutched tightly in the victim’s trembling hand. The night’s cold air promised secrets buried deep beneath calm surfaces.
