“CASUAL VACANCY” NOTE NO. 1  I’ve read the first 97 pages of J.K. Rowling’s “Casual Vacancy.”  It’s going to be one heck of a story! More complicated than I expected. Many characters, introduced rapid-fire. I do believe Ms. Rowling is going to dissect contemporary social mores and put the whole bloody mess under a high-powered microscope. Probably not for the faint-hearted. I’ll start on the review as soon as my head stops spinning.  — John
