More books (an afterthought)

As I noted in this post, I recently read Overture to Death by Ngaio Marsh which was the only book by her which my library did not have in its system and they apparently couldn’t get on an inter-library loan from anywhere closer than San Antonio. Right, so when I went to the library today for the book sale I dropped the book in the book-return box and went to look for books to buy. Lo and behold, what should I find but a copy of the exact edition I had just returned. My library system didn’t have the book because they were getting rid of it. Odd, no?
