Get what you want from even the most difficult characters All of us have to deal with difficult people. Whether we're asking our neighbour to move a fence or our boss for a pay rise, we can struggle to avoid arguments and get what we want. Laurence and Emily Alison are world leaders in forensic psychology, and they specialise in the most difficult interactions imaginable: criminal interrogations. They advise and train the police, security agencies, the FBI and the CIA on how to deal with extremely dangerous suspects when the stakes are high. After 30 years' work - and unprecedented access to 2,000 hours of terrorist interrogations - they have developed a ground-breaking model of interpersonal communication. This deceptively simple approach to handling any encounter works as well for teenagers as it does for terrorists. Now it's time to share it with the world.
