I am so far behind on your sporked chapters, it's not even funny. We're talking, almost ten chapters. But I always read the top parts about you, at least. So, on the understanding that I've only read the bit about hamsters and Ruthven...

You need to be really careful where you've based Ruthven's hideout. During the Battle of Britain, kids weren't just sent away from London and the other major cities. They were sent away from other tactical targets - such as the factories, the major ports, the radar and air bases, etc. Back then, radar was new and awesome and it was the first, crucial part of their defensive web, since the radar operators had to figure out where the enemy planes were coming from, where they were likely headed, and scramble the appropriate airbase's planes. It was their jealously guarded top secret bit of tech that gave the British's smaller air force a definitive edge against the Luftwaffe. They wouldn't've sent the kids out of the cities to live cheek by jowl with the radar or air bases.

I wish I could remember where exactly the radar and air bases were but outside of thinking 'in the north... a few in northernmost England, at least one big one in Scotland... and in the south, Dover and some others...' I don't remember. I just remember that there were a lot more bases than that.

So, uh, careful? (Or use a made up moor...)
