As is so often the case with the Maigret novels, there was some good stuff about this title that made it a good read, and other stuff that detracted from it, but I'm used to that by now, and my expectations are adjusted accordingly. This one might be more ridiculous than some others I've read, but I enjoyed it because it was set on a canal in rural France, and the observations of canal life add a lot of color.
The characters at the center of the story provide some interesting observations about class, and the portrait of the English "milord" of the title seems to be both a running joke and somehow tinged with admiration at the same time. I won't claim to understand that or anything else about the book, but if you like the Maigret novels, you'll probably enjoy this one.
How fitting that the edition I read is listed on Goodreads as "unknown binding," because the old copy I picked up fell apart in my hands as I read it (good thing it only cost a buck).
