According to Goodreads, this is one of Ms. Heyer's final novels & brings Chief Inspsector Hemingway back in the 4th of a series. One of the reviews said it would have been so much better if Ms. Heyer would have included a map of the village of Thornden. Well, in the book I'm reading, published in 1969, there is a map, for which I'm very grateful. I love the cover of the book in the photo, but wonder who it is supposed to be? The book I'm reading is plain green clothbound. Of course, after 42 years, there is no dust jacket.
I snagged Cotillion by Ms. Heyer from Amazon's free Kindle book of the week last week. I was so psyched. But it is sitting in the Kindle archive waiting for me, Detection Unlimited has to be returned to the Gooding (Idaho) Public Library in 10 days.
