Question

According to Poirot, why is Pennington incapable of committing the murders? Do you agree with his line of reasoning? If his line of reasoning is correct, who could still possibly be the killer?

Answer 1

Agatha Christie's fictional investigator Poirot is renowned for his systematic and rational approach to solving cases. He frequently uses meticulous observation and inference to find the offender. Knowing the specifics of the case and the evidence that Poirot has obtained might be useful in answering the question. It is hard to comment on his methodology or make any educated guesses about who might still be the murderer without this knowledge.
