Another good book, “based on a true story,” is Frederick Forsyth’s “Jackdaws,” about British women who went into France during WWII, and helped the Resistance. One of the few “novels” I’ve kept. I do an awful lot of reading but it’s mostly non-fiction, these days.
I’ve run across two of your stories, Bob, in my cleaning, shredding and filing, that I printed out. I suspect I won’t shred them. ;o]
I read a nonfiction book on that. Almost all of them were captured and many killed because of avoidable security breaches at the London end. The woman who ran the program, a Romanian Jew, was the inspiration for Miss Pierce in “Foyle’s War.”
I may have one or two more that could be acceptable. Let me know what you have so that then I will know what you're missing.
I know you would enjoy "Daybreak", but I don't think I've sent it to you.
