I long ago realized that I am not a big fan of "cozy" mysteries - and this book reminds me of why. The author is so caught up in indulging British witticisms, that the characterizations and plot barely register. There is also way too much plodding through minutiae that adds nothing to the story and way too much to the "pun-ish" atmosphere. In the end, one learns why the grand old lady is murdered, and how she knew what was coming, but, by that time, one cares very little, which is a shame. It should have been a thrill ride, with a lot of attention paid to the moral duties of scientific endeavor, but it comes across as pedantic and downright prudish at times. I'll give it two stars for capturing a certain British drollery, but that's all I can muster by way of appreciation.
