Parker writes the same book, again and again. It's a good book, as far as it goes, entertaining and pleasant. But it's the same. Here, we've filed off the usual names and changed the attributes. Spenser is a woman, Hawk is a gay man, Susan and Pearl are run together into a single terrier. A good time is had by all, more or less.
Over the years, Parker's style has become more and more condensed, depending every more heavily on lots of very short chapters and extremely heavy on dialog. This could be an interesting formula, I think, for hypertext entertainments.
