John Banville is writing crime fiction. Graham Greene wrote crime fiction and thrillers of a high literary quality. Alan Furst's spy fiction is second to none in any genre. John Harvey's crime novels are some of the best novels of any kind I've read. Further, crime fiction frequently has social, political and psychological insights that so-called mainstream fiction does not. I think the walls between genres are dissolving and it's about time. Some of my academic colleagues may take a contract out on me for saying this. But I don't say "I'm writing crime fiction to make money." I've published a lot of serious poetry, but I no longer consider one superior to another. I'm interested in the opinions of others on what may very well be a vanishing binary.
