I just have to say (and may have said before, in which case please pardon the repetition) that your joy in Biggles is so great that I enjoy it without even having read any of the books, and I occasionally read your fics.

It's like zoo enrichment for retired spies.
I feel like I understand them just from what you've written (and excerpted).

(I may read the books eventually, but there are so many others just crying to be read!)
