3.5ish.
This was a fun read. Very few things in this world are new, and Beauman illustrates that with Matrimony, Inc. People today might "swipe right," but partner expectations are pretty much the same (healthy, rich), although Beauman does a nice job of tracing how some partnership expectations have changed, such as pairing off for survival's sake vs. finding love.
I enjoyed the historical overview and how she put it within the context of geographical (westward expansion) and a socioeconomic context.
Beauman drives home the point that much of the success of personal ads depends on blind trust. And of course, that trust can lead to fraud...or worse. I read the whole time thinking of the serial killer Belle Gunness, so I was really glad when she devoted a chapter to her.
Criticisms? Beauman can be repetitious, especially in the earlier chapters. The images of the ads were far too small to read. It may have worked for an e-book as you can enlarge it, but I was reading the hardback, and this wasn't an option. A shame, because it's always nice to be able to read the actual source. Speaking of sources, there was no citation, which I thought was quite odd, given how much she relied on primary sources.
Overall though, a good read!
