Daniel watched Isaac change from a tortured wretch, literally writhing in spiritual pain, into a holy and purified saint. Having repented of their former sins – steadfastly purporting to lead new lives – they went back up to their chamber. Isaac pitched that drawing into the fire, opened up his note-book, and began to write. At the head of a blank page he wrote Sins committed before Whitsunday 1662 and then began writing out a list of every bad thing he'd ever done that he could remember, all the way back to his childhood: wishing that his stepfather was dead, beating up some boy at school, and so forth. He wrote all day and into the night. When he had exhausted himself he started up a new page entitled Since Whitsunday 1662 and left it, for the time being, blank.
