> I think ['The Secret War' by Brian Johnson is] an earlier version of ['Most Secret War' by R V Jones]

Most Secret War is R V Jones' memoir of his personal involvement in radar, aerial navigation, aerial surveillance etc. in British military intelligence. I read it a long time ago but I don't remember it as a dry read at all - dramatic times after all.

Brian Johnson was involved in writing and producing the BBC documentary and a book. So it's not an earlier version of the same thing. The documentary is on youtube I think - a good watch, but I'd recommend reading Jones' original book.
