This week, The Economist has a nice – and short – article about Agatha Christie and her long-lived popularity. I’m obviously fond of Christie’s books, most of which have weathered the test of time pretty well. (There are a few exceptions, and many of them do read like historical mysteries now…) And most of them go on sale pretty often too – you can keep an eye on this post/comments for sale prices.
The article is worth a read, IMO, and here’s a link.
