Once Is Enough or Twice Around

Somehow I ended up on the Times (of London) online and there I found this list of literary one hit wonders. To Kill a Mockingbird didn't surprise me, but where's Invisible Man? There's an accompanying list of spectacular second novels. They're curious, these lists, both because they're there and that they can be so fun. I can never resist a list, and I'm sure I'm not alone in that. They go down easy.
