into the middle
Horace in the Ars Poetica advises that epic poets should hurry to the middle of the story (in medias res) where the action itself happens. Otherwise, the writer will fall short of the audience’s expectations. When Frank goes to meet with Mr. Bideawhile, he intends to “rush into the middle of his subject”–that is to say that Frank intends to go directly into the events that have led to his current predicament. Frank is trying to take the advice of Horace. [TH 2005]
