This book would more aptly be called "How to Lie to People to Get Them to Tell You the Truth." The author advocates being dishonest with those you think are lying to you in order to trick them into telling you the truth. And once you have uncovered a lie, the author gives you no advice on what to do next. They've lied, and now you've lied to get them to be honest with you--now what? What people need is not a book that gives them only remotely helpful tips for telling if people are being dishonest (intuition seems to be good enough for most of us) but a book that tells you what to do with the people in your life who are dishonest with you. Catching them in a lie isn't enough--you need to know how to act to prevent the harm that lies can cause--and this book in no way teaches you that. A much better book for someone who is interested in the whole issue of lying is Sisela Bok's "Lying."
