Cold rain washed relentlessly against the dirty window glass, obscuring the gruesome sight lying silently on the polished oak floor. Lord Harrington sat upright in his velvet armchair, an ornate silver letter opener buried deep inside his completely silent chest. Detective Miller carefully adjusted his wet fedora while staring at the bloody chessboard placed directly beside the dead old nobleman. The white queen was missing from the board, replaced instead by a single black feather soaked in thick fresh blood. Somewhere in the dark house, a clock struck midnight, signalling that the ruthless killer was still hiding among the guests.
