The Thirty-Nine Steps by John Buchan

It's been some time since I read this. I had watched and enjoyed the film first, and at some point got round to reading an old, second hand, blue and black copy of the book. Enjoyed it, but can't remember much about it ... I remember the couple crossing the moor, handcuffed together, in the film, but then I've read articles since then that point out that the romantic interest was added for the film and was not present in the book, but I can't remember, so maybe I ought to read it again sometime. But there are still so many more to read ... I think I will keep plodding on.
