A temporary director, a World War II hero and a future star of the Biritish classical stage all pop in this week, but one of the regulars is far from happy nd fires of a letter filled with grievances. And that's just offscreen - as far as the viewers are concerned it's all hunky-dory: except for today's viewers of course, because this is the first instalment without telesnaps or moving footage, so it's the earliest episode of the show for which we have no evidence at all of what it looked like on screen. A mystery inside an enigma inside a Reithean tale of travel and treachery.
