Heavy rain lashed against the cracked window of the library. A single silver candlestick lay beside Lord Blackwood's cold corpse. Inspector Vance stepped slowly through the shattered mahogany double doors. Dark red blood formed a fresh puddle on the carpet. The grandfather clock chimed midnight with an ominous hollow echo. A torn parchment note was clutched inside his stiff hand. Muddy boot prints led directly toward the dark open terrace. Nobody in this locked mansion could possibly escape tonight alive.
