"Trust" author Hernan Diaz on his love for "the music of English"

Hernan Diaz writes in longhand, covering every square inch of every page in his notebooks. "I prefer to write with this pen," he said, "because if one can feel love for objects, I feel love for this pen. There is the sensual experience of writing longhand. There is something about the murmur of the pen on the paper. There is nothing like it for me."

He showed "Sunday Morning" the handwritten manuscript of the novel that just won him the Pulitzer Prize, "Trust." But he's uncomfortable, even a little bit superstitious, about letting a camera capture something so intimate and personal.

An international bestseller, published in 35 languages, "Trust" is about how money is made, the kaleidoscopic telling of the same story in four different voices – one novel comprised of four books.
