Given the complexity of the subject matter, this book was about 60 pages too long and another 250 too short.I'm kind of a, well let's just say it, expert on lying and interpersonal communication. Heck, just look at what I've been able to get across in just 2 sentences plus this one.In conclusion I think this book took a subject matter which is deserving of much more serious consideration - at least 200 more pages of such - and presented it in a fairly random and scattered fashion with "real-life examples" consisting of dialog that a That 70's Show fan would scoff at. Taking the other route, the author could have cut out at least 60 pages of fluff and Summaries which appear at the end of some sections and not others, and written a darn good pocket guide to deception-detecting.My 2-star rating means that I liked about 40% of what I read so I will check out this author's other books if I come across them.
