The rain hammered against stained glass windows of Blackwood Manor as Detective Mara Vane stepped through the heavy oak doors. Inside, the air smelled of old money, decaying lilies, and something else she could not quite identify at first glance. Lord Blackwood lay sprawled across the Persian rug, his silk cravat twisted and his eyes staring blankly at nothing above. A crystal decanter lay shattered beside him, red wine pooling like blood around the silver letter opener in his chest. From the shadows, a trembling maid whispered that nobody had entered or left the study since the dinner bell rang. Mara knelt carefully, noting how the victim's left hand clutched a torn scrap of heavy parchment bearing strange black symbols. Thunder crashed outside as she realized every guest upstairs had a motive, means, and nowhere to hide from the truth.
