The storm raged against the tall windows of Blackwood Manor, as if desperately trying to break inside the old estate. Inside, the wealthy guests had gathered in the grand library, their nervous laughter barely masking the howling wind outside tonight. Then, a blood-curdling scream shattered the tense evening, and every single guest froze, their eyes wide with sudden, primal fear. They rushed toward the horrific sound, only to find Lord Blackwood slumped in his study, his precious life brutally extinguished. The locked room presented a chilling mystery, for the killer had vanished without a trace, leaving only cold, silent dread.
