The rain drummed against the windows as Detective Sarah Martinez entered the grand library. Twelve guests sat around the mahogany table, their faces tense with fear and suspicion. "Mr. Blackwood was found dead in his study fifteen minutes ago," announced the butler, his voice shaking slightly. "The door was locked from inside, and there were no signs of forced entry anywhere." Detective Martinez surveyed the room, noting the expensive suits and designer dresses despite the storm raging outside. "I'll need everyone's alibis and any information about the victim's recent activities," she said calmly. The guests exchanged nervous glances, each wondering if they would be the next to die.
