Wow, we've had us a frenzy.  I had my own writing frenzy, too - I really didn't see how I was going to write more than five or six pages today and that's no crime at all, but after watching episode two of The Killing III, I decided to write another page or two and ended up doing six more pages - so, twelve again.  That's become the magic number with this book, I think.  Today's writing was basically feeling my way through a tricky section, but I got past that and am now into a sequence that's easy to write.  After that, then it will just be methodically going from one thing to another.
