But not this night, nor last night, but in the unfathomed night of Sunday, of the Sabbath silence.

There was Sin, the serpent, in whom was also wisdom. There was Judas with the money and the kiss.

But there was no actual Sin. If Ursula slapped Theresa across the face, even on a Sunday, that was not Sin, the everlasting. It was misbehaviour. If Billy played truant from Sunday school, he was bad, he was wicked, but he was not a Sinner.

Sin was absolute and everlasting: wickedness and badness were temporary and relative. When Billy, catching up the local jargon, called Cassie a “sinner”, everybody detested him. Yet when there came to the Marsh a flippetty-floppetty foxhound puppy, he was mischievously christened “Sinner”.
