The heavy door slammed shut with a dull final thud. Rain lashed the windows of the sprawling isolated mansion tonight. Detective Eleanor Vance stepped into the vast gloomy entrance hall. A single candle flickered on the dusty old mahogany table. She paused, listening to the raging storm outside the house. Then she heard a faint choking sound coming from upstairs. Her gloved right hand tightened around the cold silver flashlight. Slowly, she climbed the creaking wooden staircase to the landing. The body of Arthur Pembroke lay sprawled on the floor. His glassy eyes stared blankly at the cracked ceiling above. A crimson stain spread slowly across his expensive white shirt. Someone had silenced the wealthy arrogant businessman permanently that night. Eleanor knelt beside the body and studied the fatal wound. The storm outside masked any possible sound of escaping footsteps. She whispered a cold promise to find his killer soon. Outside, distant thunder crashed like a warning from the heavens. The deadly game of murder had officially begun this night. Eleanor Vance knew the mansion held many deep dark secrets.
