Many thanks Tor and Ole for the feedback on the prologue. Very useful (and very similar) comments. I realise that I probably chopped too much in the editing; also I think it is important to follow one’s own feelings (I was influenced a bit too much by a course tutor!). I’ll keep you posted as new material becomes ready. My break in Estonia has given me some new ideas, or rather conformed those that I had been tinkering with over the past month or so. Hope to get into the mountains soon to make a concerted effort to finish.
