Do you know how far away Fowey looks to someone based in London? 
The thing about being on a farm, too, is that if you stick a guard dog out the front, and/or padlock a gate at the road access, it's pretty hard to doorstep someone who doesn't want to be doorstepped.
Presumably in their shoes, you'd either lie low at home, if it was somewhere you could hole up, or get the hell out to somewhere big and anonymous before the story broke.
