This book condenses a 28 year pychiatric career into some great observations about people you know and meet in everyday life. It is interesting to anyone who has to deal with one of these "People of the Lie". I know that when I do, I have to work overtime to ensure that my sense of well being is maintained in spite of the machinations of a person of the lie. The book was very insightful and saved me from having to become a shrink in order to gain this practical knowledge.
