Rain tapped softly against the dusty windowpane late last night. The old mansion stood silent on the foggy hill above. A single lamp burned in the empty hall downstairs tonight. Detective Marie Vega stepped through the heavy oak front door. She shook her umbrella and scanned the gloomy entrance hall. A grandfather clock chimed midnight in the far dark corner. The housekeeper waited by the stairs with a pale face. "In the library," the housekeeper whispered with a trembling voice. Detective Vega followed her quietly down the long dim corridor. The library door stood ajar, spilling light across the floor. Madame Claire Aubert lay motionless on the library's Persian rug. A crimson stain bloomed across the front of her dress. Detective Vega knelt beside the body, her sharp eyes narrowing. Someone had entered the room quietly during her evening tea. A shattered teacup rested on the table right beside her. Detective Vega noticed a small key clutched in her hand. The small key was stained with something dark and metallic. Outside, thunder rolled over the hills like distant war drums. "We are not alone in this house tonight," she said. The housekeeper gasped and pressed herself against the cold wall. Somewhere upstairs, a loose floorboard creaked beneath a careful step. Detective Vega rose and drew her weapon without any hesitation. "Stay behind me," she ordered, moving slowly toward the staircase.
