Rain lashed the windows of Blackwood Manor that night. The grandfather clock struck twelve in the echoing hall. Lady Eleanor lay still upon the library floor. Her crimson gown pooled around her lifeless form. A silver letter opener rested beside her body. The butler screamed, dropping the tray of crystal glasses. Detective Miles arrived just before the dawn broke.
