Sorry to inflict this on you, Catters, but I just felt the need to unburden myself. And as it involves buying a gift for my missus, I can't share it with her.
I went to a large branch of WH Smith, a British bookseller and stationery chain, went to the books department, and asked if they had a Graham Greene anthology. The assistant - in the books department, mind - looked at me and said: "Who's Graham Greene?"
I was almost speechless. Almost. I suppose it answered my question, though.
