There is a war on truth. And the liars are winning. There is an increasingly large number of weapons in the arsenal of the rich, the powerful and the elected to prevent the truth from coming out – to bury it, warp it, twist it to suit their purposes. *Truthteller* reveals how governments and corporations have covered-up mass murder, corruption and catastrophe. In a world where Putin and Trump have successfully branded journalists as traffickers in fake news, while promoting the actual creators of fake news, an investigative reporter shows the tools that are used to deceive us and explains why they work. Using exclusive documents and interviews drawn from three decades as an award-winning reporter, editor, foreign correspondent, television producer, documentary filmmaker, and journalism educator, Stephen Davis reveals shocking details of deception in the United States, the UK, Russia, Sweden, the Baltic republics, Australia, New Zealand, Brazil, the Arctic and Antarctic. *Truthteller* is an essential guide for understanding the modern media world – for teachers, students and concerned citizens who want to know the facts, not fake news and conspiracy theories. It takes you inside the world of investigative reporting in an intimate history of a reporter’s battles, won and lost, the personal and professional costs and the lives damaged along the way.
