I'm a psychiatrist and I do not believe Fiona Harvey was lying to Piers Morgan - this is why: Dr MAX PEMBERTON

For the first 20 minutes of her interview with Piers Morgan, I believed every word that 58-year-old Fiona Harvey said. After weeks of speculation, Fiona Harvey - a woman whose alleged behaviour has brought her the unenviable accolade of the country’s most talked about stalker - broke cover Piers Morgan with Fiona Harvey, the inspiration for Baby Reindeer's character Martha, who came forward after she said her portrayal by actress Jessica Gunning was ‘taking over her life’ So why did she do it? Ms Harvey denied stalking Richard Gadd; she denied sending him 41,000 emails, 350 hours of voice messages, 744 tweets, 48 Facebook messages and 106 letters Fiona's landmark interview with Piers Morgan was viewed by more than 3.5 million people on his Uncensored YouTube show But I have frequently worked with patients with the type of ‘delusional disorder’ that Martha suffers. In her interview with Piers Morgan, Ms Harvey denied stalking Richard Gadd; she denied sending him 41,000 emails, 350 hours of voice messages, 744 tweets, 48 Facebook messages and 106 letters. Netflix drama Baby Reindeer delves into Richard's harrowing real-life stalking ordeal as he plays a fictionalised version of himself called Donny Dunn The Scottish comic played himself in the show while 'Martha' was depicted by Jessica Gunning To me, the ethics of providing her with an international platform like Morgan’s YouTube show are distinctly murky.
