This is the last in this series actually written my Michael Gruber, and I've been saving it for several years just to know that I still had it to enjoy. The series has gone on, ghosted by somebody else, and my understanding is that the newer ones aren't as good. This one was very satisfying in all the usual ways--there are several separate plots that end up being linked in unexpected ways, the courtroom scenes are very gripping, and I suspect realistic, there are arguments about law and ethics, ethics and religion, religion and philosophy, science and spirituality, all done with panache. The characters are vivid and true-to-form, consistent through the length of the series. Butch and Marlene have been together since the first volume; they have married, had three children, and the children have grown pretty much in real time over the years the books were written. The children play active roles in this one, and not just as potential innocent victims. The book was published in 2003, making the bombs, bomb-threats, middle-eastern terrorists, and setting in New York City very topical. It was a bit more grisly than I remembered others of the series, but since the main villain was a psychopath, this was probably necessary. As fitting an end to the series as the title suggests. (An end for me, at least, since I doubt if I'll read the subsequent ones.)
