Anthony Horowitz quotes an interview with Giles Foden, author and professor of creative writing at the University of East Anglia.
At any event, he was asked—broadly—about the place of literary books in the new world and he replied: “It’s hard to establish what is good and what is not. Barnes, Amis and McEwan were the last people through the door and then the door closed and the building fell down.”
I don’t think the situation is getting worse for literary writers. Yes, literary fiction comprises a small portion of the market, but this has been the case for decades, perhaps longer. And while the chefs’ books and celebrity memoirs are popular during their marketing window, they don’t last. Literary fiction — and good fiction in general — has a long tail.
