This may be a bit niche but does anyone know of a podcast (or audiobook), preferably history, crime, or mystery, that is narrated by someone who speaks RP English or has pronunciation like John Cleese or Joanna Lumley? I've tried loads of different podcasts and books to help me sleep but my mind focuses on any pronunciation that it decides is wrong or odd, and then won't shut off. I tried Mythos by Stephen Fry as I usually love listening to him but my brain didn't agree with the way he said certain names so I couldn't listen to it.
Please don't think this is me hating regional accents or anything like that. I do usually love most accents (and I definitely do not speak RP English!) but just not when I'm trying to turn my brain off.
