Why Does Herr R. Run Amok?

Plot
Herr Rabb has worked for 18 months at a small architectural firm and displays loyalty and respect for his colleagues. He and his wife harmoniously attend a parent-teacher conference, watch television and plan for the future. They visit his parents, where his mother seems slightly overbearing. He was rebuked at work and his son could be doing better at school, but these do not seem to be serious issues. His wife tells friends that he is anticipating promotion to another office. Rabb is at work, getting his health check-up with few issues apart from slightly raised blood pressure and persistent headaches, and later making an embarrassingly tipsy speech at a dinner-party for his colleagues and boss, after which his wife calls him fat and stupid. Herr R. watches television with his wife and a talkative neighbor. After listening to the neighbor talking about her skiing trip, Herr R. gets up and silently bludgeons to death the neighbor, his wife and son, Amadeus, with a large candlestick. The next day, he reports to work on time. When the police arrive, they find he has hanged himself in the bathroom.
