I’m at the post office most days, because I get my mail there (at a P.O. Box). Next door is the local branch of The Salvation Army. A few years ago I discovered they have a nice used-book selection, and since then have bought a lot of books there.
Here are two of them; both are part of the Maigret series, by Georges Simenon. I hadn’t read any of Simenon’s books before these, and enjoyed both very much.
