Well done
@Ming the Merciless. All fairly straightforward, then.
Riddon Brake, which was practically spelt out, is rather a nice house, but the trees within its grounds almost completely hide it. The 1:50,000 map shows it as a clump of trees but the 1:25,000 marks it as a house.
Until Ming drew attention to the clump of trees I was intending to use a different clue. Perhaps "Held woman escapes to distant ridge" would have been too obvious.
I rode along that road once, at night. A good friend, also my most significant cycling mentor, was retiring, and moving from Wrington, south of Bristol to Scotland. To mark the occasion he organised a four-day ride from Land's End back to his home, and all his old cycling friends were invited - in February. I could only commit two days, so at the appropriate time I left work early, took the train to Newton Abbot and set off for Postbridge in rapidly fading light. A remember a car driver somehow managing to register his concern for my safety as I left Ashburton, and it was easy to see his point. The lowest gear on my bike would've been 35/32 - not low enough and not being able to see where the road is going does nothing for the resolve. By the time I reached the spot in the picture I was almost home and dry, but there was a nasty sting in the tail after Bellever.
Over to
@Ming the Merciless again.
