Detective Mara Ellison arrived at the rain-soaked manor just before midnight, finding the front door ajar and eerily silent inside. A candle flickered in the grand hallway, casting trembling shadows across portraits whose painted eyes seemed to follow her movements. She discovered Lord Henry Blackwood slumped over his mahogany desk, a silver letter opener protruding from his back, blood pooling. The unfinished letter beneath his lifeless hand contained one chilling sentence warning her never to trust anyone present that evening. Upstairs, seven dinner guests waited nervously in the library, each claiming innocence while exchanging glances heavy with secrets and suspicion. Mara closed the study door, examined the untouched whiskey glass beside him, and quietly wondered which guest was lying now.
