Rain hammered the windows while Detective Mara Vale studied blood. The victim lay beneath a shattered chandelier in the hall. A silver letter opener protruded from his chest, an accusation. No footprints marked the polished floor, which troubled her instantly. She knelt beside him and whispered, "Who hated you enough?" The answer arrived as a gunshot shattered the hallway mirror. Mara drew her weapon and spun toward the dark staircase. A woman laughed above, sounding so cold and impossibly calm. The killer was still inside, and the storm sealed exits. Mara checked her phone, but no signal met her eyes. "Come upstairs, Detective," the voice called sweetly, "I am waiting." Mara ascended slowly, knowing the first clue was also bait.
