Just finished the newish Galbraith/Rowling Strike/Ellacott mystery,
The Running Grave. I found it the best of the series -- generous in length, and generous to the characters.
I read a review suggesting that Rowling must be rejecting cuts advised by her editor. Sounds correct, but some great nineteenth century classics also were weakly edited. This outing, I think it was for the best, giving room to make series regulars multi-dimensional.
I don't read mysteries to guess the chief villain, but for those who do, the plot is complicated. A list of characters can help, and Rowling
provides one on her web site.
