This is a fascinating piece of true crime writing centered around the 1960's Boston Strangler case. It has a personal twist, as Junger's young mother had briefly hired a handyman who later confessed to many of the killings. Although it was a more transient relationship than Ann Rule had with Ted Bundy, there were moments where the author (and of course, the reader) are left thinking, "Oh god, what if..." 
 Those encounters, of course, became part of the Junger family lore, which prompted the author to investigate the case himself and re-examine as much evidence as he could gather in pursuit of the truth, which was hazy at best. If DNA evidence could have been analyzed at the time, we might know the truth, but that wouldn't be a possibility for another 30+ years. The case was left mired in racism, inconsistent testimony, and circumstantial evidence.
