I'm back at 4 Folly Bridge again (home of Goose Castle) but this time, the evening sun has caught the roof, where a bright green little garden is nestled among the statues, battlements and dramatic chimneypots. It must be vertiginous - the house is at least four stories high.
Soft pine trees are just visible over the turning-japanese fencing, with box balls and other low pots enclosing a small, private space (if anyone is up there, they would have to stand up and look around for me to see them). Either genuine lead troughs or a more practical plastic facsimile put lavender at shoulder-brushing height as you head for the steps.
The third lavender pot his suffering in the dry, but also has a suspicious gap in the centre of it; almost exactly as if a pigeon had nested there.
