Final answer:
The ending is unusual as Mr. Crick escapes punishment due to a skilled lawyer, highlighting the fairness issues in the justice system.
Step-by-step explanation:
This ending is unusual because it goes against the typical narrative structure where the protagonist solves the mystery and the culprit is held accountable for their actions. Instead, Mr. Crick, the antagonist, escapes punishment due to the influence of a skilled lawyer.
The moral point being made about fairness is that the justice system can sometimes fail to deliver a just outcome, as it prioritizes legal loopholes and the power of representation over the truth. This raises questions about the fairness and efficacy of the legal system and highlights the importance of ensuring equal access to justice for all.
