Cormac McCarthy, who died on Tuesday at 89, was a great American novelist who tackled what he regarded as great American themes: history, violence, the nature of evil, the myth of the West. His 12 novels, which remodeled the cheap set pieces of genre – especially the Western and the crime thriller – were exceptionally bloody. He wrote in two stylistic modes, per New Yorker critic James Wood: His prose could be flat or ornate, terse or maximalist. (In all cases, he tended to eschew commas.)
