In To Kill a Mockingbird, what were the three small things out of the ordinary that happend in Maycomb? Who is responsible for the last two things?

These are the events just prior to Halloween as described by
Scout in Chapter 27 of To Kill a Mockingbird. First, Bob Ewell "acquired and
lost a job in a matter of days." Work was something foreign to Bob, so it's no surprise he was
fired for "laziness." However, Bob blamed Atticus for getting him fired. Second, Judge Taylor
discovered a prowler outside his back porch with the screen door left open. He only got a glimpse
of the man's shadow as the prowler made his escape, but he was ready and waiting for him later
with a shotgun in his lap. Next, Helen Robinson, Tom's widow, was harassed by Bob Ewell as she
walked to work. Bob "chunked at her" and later cursed at her before he was threatened himself by
her boss, Link Deas. So, Bob Ewell was responsible for two of the situations--and it was probably
him that Judge Taylor saw fleeing from his porch as well.
