The heavy rain lashed against the cracked windowpane as Detective Miller entered the dimly lit room with his notebook open. His boots squelched loudly upon the soaked carpet while he studied the lifeless body sprawled across the worn velvet chair. A single bullet wound marred the victim's chest, and a strange silver locket rested heavily within his tight clenched hand. The old clock on the mantelpiece stopped ticking exactly at midnight, and the silence suggested time of death to all. Shadows danced across the peeling wallpaper as Miller crouched to examine the pool of dark blood near the rug's edge. He pulled a magnifying glass from his coat pocket and turned it over the symbols he found on the floor. A sudden scream echoed from the hallway, causing Miller to spin around and call for the partner near the door. Miller grabbed his revolver from the table and marched quickly toward the sound, hoping to catch the culprit before escape. The hallway stretched endlessly in both directions, filled with ghostly portraits that seemed to watch him with knowing, malevolent eyes. He reached the first door on the left and threw it open, finding only the empty closet inside the wall. Another cry pierced the air as Miller sprinted down the corridor while his heart hammered loudly against his ribs inside.
