Genre and Literary Fiction: Whither le Carré?

Adam Sisman’s JOHN LE CARRÉ: THE BIOGRAPHY gets off to a good start – in my book – with Sisman’s Introduction, when he says that the ‘condescending attitude taken by some towards le Carré is explained in part by the idea that ‘genre’ novels are innately inferior’:

“To me, the argument about whether a genre novelist can ever be ‘literary’ is a circular one. The very distinction is meaningless. Is Jane Austen a genre novelist? Is Nineteen Eighty-Four a genre novel? or A Tale of Two Cities? or Wolf Hall? or The Quiet American? All that one can usefully say is that there are good novelists and bad novelists. […]
“I suspect that his enormous success has prejudiced some critics against le Carré. If a writer is so popular, he must have lowered himself to the level of the masses. Quite apart from being manifestly untrue, this is no more than snobbery. We should delight in the fact that such a sophisticated and subtle writer has so many readers. A further problem for le Carré is that his books are often tense, exciting and even thrilling – qualities not often present in literary fiction, and ones that perhaps disqualify him from entertaining the pantheon.
“I see an analogy with Alfred Hitchcock, a filmmaker whose artistry was often overlooked in his lifetime because he made the mistake of being popular. The novels of le Carré blend art and entertainment, a mix to be relished by those who have the taste to enjoy it.” ~ Adam Sisman
