Rain hammered the windows of Blackwood Manor that endless night. Detective Mara Quinn arrived precisely at midnight, soaked completely through. Butler opened door, his face pale as fresh fallen snow. "She's upstairs," he whispered, refusing to meet her eyes directly. The library smelled of old paper, perfume, and fresh blood. Lady Blackwood lay sprawled across her crimson velvet chaise lounge. A letter opener protruded from her chest, handle glinting ominously. Mara noticed second glass of wine, still suspiciously warm nearby.
