This is a very classy addition to the Maisie Dobbs series, but it smacked of being the last of the series. Everything tied up neatly, so that I don't see any place for her to move on to. Maizie is hired by a wealthy American family to find a former nurse in France in WWI with whom their son had fallen in love before he was killed. And killed had more than one meaning, since it developed that he was murdered before his bunker was attacked and everyone else died, too. Not only did we find out all about the cartographers of the service, which I had never really thought about existing, but we found out lots more about the English nursing corps. Many of the nursing stations were not set up by the military, but by any charitable or privately-funded organization that took a notion to do so. I don't know how there was any order in the system. Maizie's personal life takes on new dimensions, too, so that added interest. Yes, a very good outing. I have at least a couple of books in the middle of the series that I need to delve into, also. I realized in the course of reading this one that I have gaps in her story. I'm glad, because that gives me reason to read more in this lovely series.
