Final answer:
The texts provide no direct information on an accident involving Monsieur the Marquis in Paris; they only suggest a volatile and dangerous atmosphere. Character reactions to misfortune and disturbances vary, reflecting the author's depiction of violence as an almost expected aspect of everyday life in Paris at that time.
Step-by-step explanation:
The question asks about the "accident" that befalls Monsieur the Marquis in the streets of Paris. No specific incident involving Monsieur the Marquis and an accident in the streets of Paris is directly described in the provided texts.
However, multiple events in the excerpts hint at the volatile atmosphere of Paris during the time, such as the behavior of a man with a musket causing a disturbance (frantic behavior).
The comparison of a character’s reaction to a natural disaster to a cyclone (reaction to misfortune), and the general sense of impending peril a character might feel in the Parisian political climate (Parisian police).
From the information given, it seems that the author views violence as a common and almost expected occurrence in the Paris of that time, with characters reacting to it in various ways, whether with calm, disdain, or acceptance.
The reaction of Parisians to violence, such as the September Massacres, is not detailed in the text provided, hence it’s not possible to give a definitive answer about their overall reaction to such events.
