"But even before Curtis left the Monthly, he had begun experiencing one of those rare periods of flow that sometimes envelop creative people, when far-flung pieces of complicated puzzles converge, announcing their meanings in clear tones, and time seems to stand still in a continuous present of focus and commitment. When everything, basically, just seems to come together.

"It's more fun than anything I can think of, to do a good story. It's almost," Curtis says now, "like you're on a surfboard."
