Heavy rain hammered violently against the stained glass windows of the grand manor as midnight struck the grandfather clock downstairs. Detective Miller walked very slowly toward the dimly lit library because somebody reported a terrible scream echoing through the halls. He pushed open the thick wooden doors and immediately saw Lord Harrington lying perfectly flat on the expensive Persian carpet. A silver dagger protruded deeply from his chest while a pool of crimson blood quietly soaked the delicate carpet fibers. Miller knelt beside the cold corpse taking note of a crumpled piece of parchment clutched tightly in the frail fingers. He carefully extracted the secret note discovering a cryptic message written hastily with strange dark ink that resembled fresh blood. Five guests remained trapped inside this isolated mansion because the massive stone bridge outside had totally surrendered to rapid floodwaters. One of those seemingly innocent and terrified individuals was actually a ruthless killer hiding behind a mask of profound grief. Thunder echoed loudly overhead causing the flickering lights to completely fail just as a floorboard creaked directly behind the detective. He slowly reached toward his loaded revolver anticipating an immediate attack from whatever malicious creature lurked within the oppressive shadows.
