Heavy rain beat relentlessly against the grand manor'sstained glass. Detective Miller stepped cautiously over the threshold into the hall. Lord Blackwood lay motionless upon the expensive Persian wool rug. A silver letter opener protruded from his tailored velvet jacket. Blood pooled slowly beneath the cold body of the billionaire. Nobody in the silent house claimed to hear a sound. The grandfather clock struck midnight with a low, ominous chime. Miller noticed muddy footprints leading toward the locked library doors. Someone inside this magnificent estate was hiding a deadly secret. The long night of ruthless interrogation was just beginning now.
