When Shanna Edwards weird new neighbor moves in next door, things begin to go haywire, including her discovering her friends grisly, bloody head decorating a fireplace mantel. Meeting Dr. Stevens, San Diegos acting medical examiner and chief forensic pathologist at the crime scene, the two begin piecing together the puzzle of fifty-three murders marked NHI (no human involved) on crime reports. The serial killer stalks prostitutes and runaways, believing hes purifying the human race of an infestation, a sickly disease of street trash. Before hes through, at least fifty-three women will be dead. Unlike previous serial killers, he finds creative new ways to murder, mutilate, and dump the bodies, aided and abetted by the indifference of the chauvinistic SDPD. Shanna, an ex-cop, and the ME open a Pandoras box of intrigue as their investigations lead them to believe that San Diegos killer is in reality Washingtons Green River Killer or his protg. So many twists and turns in the investigation will keep a reader holding her breath for the next surprise revelation.
