The detective stepped into the lavish study, eyes scanning the room. A single gunshot echoed through the silent mansion's halls that night. The body lay sprawled across the Persian rug's intricate design. Blood pooled beneath it, slowly seeping between the fibers deep. Nowhere were the screams from the shot to be heard. Or any sign of struggle or combat in the vicinity. It was as if the victim had no prior warning. The killer seemed to come and go unnoticed by everyone. No one guest had anything to say about the occurrence. The detective's mind raced with possibilities and theories at once. Time was of the essence in solving this crime scene.
