The rain drummed against the old mansion’s broken windows tonight. Flickering candlelight cast long shadows across the abandoned hallways. A single footstep echoed where no one should have walked. Detective Mara Voss adjusted her coat, gripping her revolver tightly. The butler’s stiff smile vanished as she stepped inside the door. "Something’s wrong," she muttered, though no one answered her words. A scent of lavender lingered, mixed with something far darker. The grand clock struck midnight, its chime sounding like a death knell. Mara’s flashlight revealed a name carved into the polished floor. *Eleanor Whitmore—murdered here last night, they had said.* The door to the library creaked open on its own. Inside, a figure stood over the body, knife still glistening.
