The manila envelope arrived late in the evening. Inside was a photograph of a blood-spattered crime scene. No note, no indication of who had sent it. This was a first for'investigative journalist Anna. The photo seemed to depict a human body in some sort of industrial facility. Zooming in revealed a grisly detail: that the victim was barely recognizable as human. Anna felt a chill run down her spine. This case would be the biggest and most disturbing of her career. It was the start of something truly terrible.
