Readers walked away, their faces lit up because they'd met him, while his was lit up because he'd met them. Henry had written a novel because there was a hole in him that needed filling, a question that needed answering, a patch of canvas that needed painting -- that blend of anxiety, curiosity and joy that is at the origin of art -- and he had filled the hole, answered the question, splashed colour on the canvas, all done for himself, because he had to. Then complete strangers told him that his book had filled a hole in them, had answered a question, had brought colour to their lives. The comfort of strangers, be it a smile, a pat on the shoulder or a word of praise, is truly a comfort.
