I'd like to know what they're doing there,
gpt
So would I, but it's open country, and they're probably keeping a close lookout. They're really safer doing that in the open than on the roof of a house, out here in the country.

Because they can hide the heliograph? It's portable, isn't it?
gpt
Yes. They could stow it away in a minute, if they were alarmed. I fancy we'll find them using hilltops now as much as they can.

Harry, I've just thought of something. If they've planned so carefully as this, wouldn't they be likely to have country places, where they'd be less likely to be disturbed?
gpt
Yes, they would. You're right, Dick. Especially as we get further and further away from London. I suppose there must be plenty of places a German could buy or lease.

And perhaps people wouldn't even know they were Germans, if they spoke good English, and didn't have an accent.
