Rain hammered the windows of the old manor as the clock struck midnight, echoing through empty halls, shadows dancing ominously. Detective Clarke arrived at the manor, his coat dripping, to find the library door ajar and a silver candlestick overturned. A cryptic note lay on the desk, its ink still wet, hinting at dark secrets within the ancient family itself. The body was absent, but a chilling silence suggested the murderer might still lurk somewhere in the shadows nearby perhaps.
