What is the falling action in the Invisible Man By HG Wells?

The falling action begins when Kemp alerts the police. When the police arrive, Griffin violently assaults Kemp and a policeman before escaping, and the next day he leaves a note on Kemp's doorstep announcing that Kemp will be the first man killed in the Reign of Terror. Kemp remains cool and writes a note to the Colonel, detailing a plan to use himself as bait to trap the Invisible Man, but as a maidservant attempts to deliver the note she is attacked by Griffin and the note is stolen.
