I couldn't find this book in bookstores, and interlibrary loan laughed at me when I tried to request it. I was thrilled to find a copy at Goodwill in the $.89 bin and in good condition to boot.
I enjoyed the book. It was amusing, interesting, and featured a lot of Miss Marple. Since she doesn't always get to spend too much time in her books, this is notable.
However, this is also the first Agatha Christie in which I've guessed the whodunnit, the motive, and the method long before our heroine. I thought I'd be thrilled when I finally beat Dame Christie, but instead I'm kind of disappointed.
