What’s the difference between a story and a plot? you ask.
According to E. M. Forster (whom Jane used to refer to by his middle name, as did everyone who knew him), ‘the king died and then the queen died’ is a story, but ‘the king died, and then the queen died of grief’ is a plot. Not so, Edward, not so, Morgan! ‘The king died, and then the queen died of grief’ is still a story. To mutate into a plot, a story needs a further element – easily supplied, here, by a comma and an adverb.
The king died, and then the queen died, ostensibly of grief is a plot. Or a hook. Plots demand constant attention, but a good hook can stand alone and untouched, like an anchor, and keep things fixed and stable in any weather. Plots and hooks yield the same desideratum: they set the reader a question, with the implicit assurance that the question will be answered.
