“ This is a picture of him from 1919, just after the war, looking like he slept in that uniform all the way from France. He still had that face, but he wasn't the same. I know there's men who came back changed: the Paterson boy up in Brownville hung himself that summer. Nobody talked about it much, and I suppose that was for the best. But Jack wasn't like that; it hadn't been a terrible thing for him, I don't think. Or if it had been, then it was one of those terrible things you get through and it sets you free. ”
