The heavy oak door creaked open very slowly, revealing a dark study filled with long shadows and deadly silence tonight. Cold rain battered the tall glass windows while the quiet inspector examined the crimson stain upon the old Persian rug. A silver letter opener rested near the fallen victim, gleaming faintly beneath the flickering electric lamp upon the mahogany table. The old grandfather clock struck twelve times while thunder shook the walls and rain poured against the glass panes below. A single photograph lay face down upon the leather chair, hiding the true identity of the young mysterious stranger forever. The silent sergeant adjusted his heavy coat and examined the bloody knife resting beside the pale left hand very carefully. Whispers floated through the open doorway, carrying dark warnings about the dangerous secrets hidden within these very old brick walls. Midnight approached quickly as the lead investigator realized this brutal murder would change everything he knew about absolute moral justice.
