I have always loved denouements, the sort of settling-down-and-wrapping-up phase that often (though not always) follows the climax of a story. I need that time, that space, to process what has just happened. I want to stay with the characters a little longer. A denouement is like that moment of silence following the end of a symphony when the echoes of the last note are still dying down, and the audience is not yet ready to break the spell with applause.
does a magnificent job of discussing the value of denouements. A
sample: "No one wants a book to drag on too long, but it’s just as
dangerous for a book to end too soon ..."
