Detective Vance stared at the lifeless body on the marble floor. The victim’s sapphire eyes were wide open, staring at nothing. A single red rose lay across his chest, perfectly placed. No signs of struggle marked the room, only eerie, calm silence. The grandfather clock ticked on, oblivious to the grim scene. Vance crouched down, his sharp eyes narrowing at the corpse. A faint, bitter-almond scent lingered near the man’s pale lips. Death had arrived quietly, without breaking a single window pane. He noted the spilled wine glass, shattered beside a leather chair. The dark red stain on the rug looked more like blood. Outside, heavy rain began to beat against the frosted windows. Justice would have to piece together this perplexing, silent crime. Vance removed his hat, revealing a deeply furrowed, weathered brow.
