Poison Mind
Many of us have had neighbors whose loud music, objectionable habits, or destruction of property get on our nerves. This is the story of a man who gotsoannoyed, he poisoned his neighbors  with an extremely painful nerve toxin. The personalities are what  make the book: the cartoon-character nerd who was a disgruntled  househusband to a female orthopedist, the quietly charming policewoman who went undercover to get the goods on him, the loving Southern family who suffered so much. And there's a revelation at the end of the story that will appall you. As theNew York Timeswrote, "Florida, the cradle of creepiness in detective fiction, offers up some weird criminals in real life, too.... The authors are good at portraying the oddly disconnected society of small-town Florida, as well as the man who almost committed the perfect crime there."
