Why did Emily Maitlis, the former Newsnight presenter, want to make eight programmes about an American official who died 50 years ago?
Roger Bolton asks her about her Radio 4 series which recounted the career of J Edgar Hoover, the man who made presidents tremble and became probably the most powerful non-elected official in the USA. Was he the \\u2018deep state\\u2019 personified?
Also, Dr Michael Moseley of Radio 4\\u2019s Just One Thing answers a critic who says his advice to eat more oily fish could come at a high environmental price.
And in a similar vein, should we be concerned about the future of peat bogs?
