Award-winning journalist Gary Nunn investigates psychics, mediums and astrologers to understand their uncanny power – and whether it's used for good or evil.

Gary has always been a sceptic. His sister Taren, an avid believer, consults mediums to navigate a family trauma. When Gary reports a news story about a clairvoyant's link to the collapse of a huge stockbroking firm, personal questions become professional. Why do such large swathes of the population want their fortunes told? Why this need to believe? What is he missing?

So begins a two-year investigation into the mysterious, unregulated world of psychics. Gary tries some out himself, sometimes with hilarious results. He hears about their involvement in the media, the corporate world, government, the criminal justice system and beyond. As we wade further into the post-truth era, Gary unearths the unprecedented power of psychics today.
