The clock struck midnight, echoing through the empty, silent mansion. Shadows danced eerily, cast by the flickering, dim candlelight. A chilling wind howled, rattling the ancient, creaky windows. Footsteps echoed ominously, growing louder with each passing second. The butler entered, his face pale and eyes wide. He discovered the lifeless body sprawled on the floor. Blood pooled around, staining the expensive, Persian rug. A single clue lay beside the victim's hand. The detective arrived, surveying the grim, unsettling scene carefully. The investigation began, secrets lurking within the mansion's dark corners.
