Best book so far! Worrals and Frecks decide to build a pop-up aerodrome and refuelling station in the Cévennes so that the RAF can ferry Spitfires to Malta. (This was written in 1943, so the forward notes that it takes place before the Nazis occupied all of France. There is no note telling starry-eyed young women that joining the W.A.A.F. will lead to none of this.) They are given the blessings of the Biggles crossover character who runs Definitely Not the SOE, and sent on their way. Shenanigans immediately ensue.

I'm always uneasy about asking for German PoV in WWII stuff, but I fully want the mission reports of all the random people who run into Worrals and have no idea what the hell just hit them. One of the highlights of the book: periodically the same character comes by to bring them more aviation fuel, and they catch him up on how it's going, while he mutters "What the fuck?" over and over again under his breath. There's also several fun French Resistance characters (organisation not quite called that, since this came out in 1943), who mostly want to push people down ravines where their bodies will never be found.

If I have a quibble, it's that there are next to no female characters aside from our heroines. Especially in a book about the French Resistance, it feels like there's room for a lot more, but almost all of the active and incidental characters are male. In previous books at least we got an old lady and a barmaid who were part of the resistance, but nothing here except a landlady towards the end and a variety of unnamed shepherdesses.
