Dark rain poured heavily across the abandoned mansion last night. Detective Vance stepped inside through the shattered front glass doors. Cold wind whispered through empty hallways filled with deep shadows. He found the wealthy victim lying beside the grand fireplace. Silver blood stained the expensive rug beneath the lifeless body. Someone had ended Mr. Blackwood's miserable life very quickly.
