'The latest work in the burgeoning espionage self-help genre ... In a broader sense the book also represents the deep infiltration of counter-intelligence techniques into civil society' -- The Times 'Amateur Psychologists will love this book by four former CIA officers, which plunges into the intricacies of lying, how to spot lies and how to react to them ... This is a proper account of deception replete with graphs, tables and sample interviews which pinpoint lies in all their glory. An absorbing work.' -- Sunday Business Post 'The publication of a book written by three former CIA agents claiming to teach the reader how to detect deception couldn't be better timed.' -- Time Out 'A brilliant piece of writing which will enable anyone who needs to know when people are lying make a value judgment.' -- Books Monthly
