Thanks. I always loved those books but, when it came to it, I'm not sure whether the long row on the shelf ever actually included that one. So I read it on Kindle yesterday. I don't recall a Ransome in which bikes got quite so many mentions
One of the things I like about the books is the echoes of a world in which kids went off exploring, sailing (and cycling) for a day or more at a time. And I always remember the use of Semaphore in
The Picts and the Martyrs and others.
