Rain hammered the windows as thunder echoed beyond dark hills. Detective Mara Quinn arrived before midnight despite the flooded roads. Inside the mansion, silence hung heavier than the storm outside. A silver candlestick lay beside the library's cold marble fireplace. Lord Ashworth slumped forward, blood darkening his white silk shirt. His trembling housekeeper whispered that everyone heard a gunshot earlier. Yet no bullet wound marked the body lying before her. Mara noticed poisoned wine glittering inside his overturned crystal glass. Upstairs, a door slammed although every guest claimed innocence tonight. Someone here had lied, and Mara intended to expose them.
