Final answer:
The provided excerpts are not from 'To Kill a Mockingbird', making it impossible to accurately answer the question about the three threatening events in Maycomb.
Step-by-step explanation:
The student has asked about the three threatening events that occurred in Maycomb by the middle of October in the novel To Kill a Mockingbird. However, the excerpts provided seem to be from different literature pieces rather than the specific incidents from To Kill a Mockingbird. Therefore, I am unable to accurately answer the question based on the given references. To correctly respond to the inquiry concerning Maycomb's troubles, one should refer directly to the content in To Kill a Mockingbird by Harper Lee, which is not included among the excerpts.
