In just 10 or 20 pages, the story writer must, like the novelist, create the illusion of a whole and entirely credible world.

I find this entirely credible.

Alternatively, it's feasible, if not entirely credible, that you've managed to accidentally pack five pairs of heavysoled brogues for your week in the sun — again.

This lends a rock-solid sense of authenticity, and the other actors give entirely credible performances as well.

But the novel doesn't quite work - the plot has many inconsistencies, the characters aren't entirely credible, the narrative voice strives too hard for effect.
