This story has many subjects of evil & secrets. At a Halloween party in the Drake house Joyce a young girl tells the guests she saw a murder when she was younger but that she never reported it because she did not understand that it was a "murder at the time". Joyce was known for telling stories that no one believed and she was disliked by her brother. Later she is found drowned in a tub of water used for bobbing apples at the party. Many are people murdered in this episode
Lots of tension, fighting and mystery going on. An adult brother and sister at odds with each other, young siblings dislike one another both end up dead.
Olga a woman from another country was to inherit the Smythe fortune. People think she went back to her country. A woman is/was having a affair with Michael the gardener. Human sacrifice is spoken of to a girl that is susceptible to the man who tells her if she dies others will live, suicide of a lesbian made to look normal by the female speaker "Beatrice could not reconcile her true nature" and a bunch of bull used to get sympathy for the female that loved Beatrice. Poirot does not say anything as this pompous woman speaks of her love for Beatrice. Poirot the "so called Catholic" that makes the sign of the Cross in other episodes says nothing. When does he ever not say nothing!??
Many of the people that go to church in this village are all hypocrites. This places Christians in a bad light but it also shows that those who say they are Christians do not live by the teachings of the Bible or have faith in Jesus.
In the end Poirot is in the garden where a body was buried. Guess what! He does the sign of the Cross and says "Halloween is a time to light a candle for the dead". I agree my birthday is on Halloween October 31st and I hate the celebration of Halloween. My faith is in my maker Jesus Christ and I thank Him for the blessings He has given me all my life especially my parents and children.
