I have been away in Central Otago reading a lot about Scottish Battles and studying maps of Scotland. I was fortunate enough to have to take one of the kids (who'd come of his bike) to Maniototo Hospital and grilled the dear doctor about all sorts of horrendous things which happen to the body after being shot by the bolt of a crossbow, stabbed, cut, etc etc. He gave me lots of details about complications and how long death takes - brilliant.
I have about six chapters to go until I have finished the SFD of the last third of the book. Then, I shall gather up all the comments I've received and start going through it again.
