While this book started out slowly, I was hooked by the end. The author describes everything in detail, sometimes a bit too much for my taste, but it certainly leaves you with a vivid picture of Paris in the early 1900s. After the slow start, the plot really picks up, and I found it difficult to put down. This is a good book for anyone who likes historical fiction and mysteries!

Overall, I enjoyed reading this book. Some of it was a bit dry and factual, but some of it read more like a novel. I have lived in the Boston area for the past 10 years and rely on the subway for my commute, so it was interesting to learn a lot about the history of the T and about some of the historic figures who lived here. The author does a good job of depicting how difficult it was to get subways in both New York and Boston approved, not to mention built, and I feel like I appreciate the public transportation system a lot more now.
