"Leaf by Niggle" is a lovely story, all about how art is used to introduce Niggle, his neighbor Parish, and Parish's wife (maybe we don't see her get 'there' but it was implied that she was coming) to heaven. I won't spoil the story (any more than I already have) for those of you who have not read it yet.
It's well worth the read, as I said it's a lovely story.
(And that's high praise coming from a cold, cynical person like myself
)
So read it!!
