If you have read the original, I suggest you revise it yourself.
1. Miss Russell
Let's see what's wrong with the knee.
The second question is not easy to say. In the original text, Miss Russell first discussed the problem of rubbing medicine on her knee with the doctor, then began to talk about the important harm and cocaine, and asked the doctor about the drugs for detoxification. Finally, she asked the doctor if there was any poison that could not be tested. )
The reason for changing the topic of poison suddenly is that I don't want the doctor to pay attention to why she asks questions about cocaine.
2. Poirot and Ralph Peyton
I'm not sure about this problem. I suggest you consider it carefully.
Poirot happened (a pumpkin flew from Poirot's yard to the doctor's yard)
Ralph seems to be in crisis because of the doctor. Ralph may know about the doctor's blackmail.
I feel this way about this problem, but it feels strange. . . )
I don't quite understand the meaning of this question. If the conversation shows the doctor anything, it is that Ackroyd already knows that Mrs. Flores has been blackmailed, and Ackroyd will immediately know that the blackmailer is the doctor (if he reads the letter).
Parker came to deliver the evening mail.
If it's about delivering letters,
Mrs Ferras poisoned her husband to marry Ackroyd and was blackmailed by the doctor.
She finally couldn't bear to confess to Ackroyd, but said it would take 24 hours to name the blackmailer, but she was soon found to have committed suicide. The letter that the doctor sent when talking with Ackroyd was written by Mrs. flores the night before, and it mentioned the name of the blackmailer, so the doctor killed Ackroyd.
4. The police inspector suspected Parker
The reason is hard to say. According to the doctor's testimony, Parker called the doctor and informed him that Ackroyd had been killed. Parker overheard the conversation between the doctor and Ackroyd (in part). He was nervous when he was questioned by the police and said some extortion words, which is probably the reason.
Ralph Peyton
Ralph has been in serious financial difficulties recently, and Ackroyd's death will bring him a lot of wealth.
He was seen near Flynn's compound at 9: 30.
The shoe prints in the study match Ralph's boots.
Flora, Ralph is suspected of a crime. Flora insisted on inviting Poirot to attend in order to clear Ralph's suspicion.
6. Flora and Brent, this conversation feels ordinary. Poirot knows that Brent has a crush on Flora (from the conversation), and Flora has been living a dependent life, which is very useful for analyzing what they are hiding in the future. When Poirot appeared and talked with them, he found ursula's wedding ring in the swimming pool.
7. Lost 40 pounds in Ackroyd's bedroom.
Flora
According to Flora's testimony, she went to the study at 9: 35 pm to say good night to her uncle, but in fact Ackroyd was dead, which blurred the real time of death and increased Ralph's suspicion.
8. Mrs Ackroyd: On the night of the murder, Mrs Ackroyd stole some old silverware from the silver cabinet.
Flora: Flora stole 40 pounds from Ackroyd's bedroom on the night of the murder and happened to meet Parker when she came downstairs. In order to avoid Parker's suspicion, she assumed that she just came out of the study to say good night to her uncle.
Raymond: Raymond owes 500 pounds, and part of Ackroyd's will can just help him tide over the difficulties. But he didn't say it for fear of being suspected.
Brent: Brent is in love with Flora and thinks Flora likes Ralph.
Doctor: The doctor and Peyton are good friends. On the night of the murder (that is, after he killed someone), he met Payton and advised him to escape (in fact, it was mainly to increase Payton's suspicion and shift the focus).
9. Miss Russell: Miss Russell has an illegitimate child. . . ) Charles Kent began to drink and take drugs when he grew up. He recently returned to England and learned that his mother was Miss Russell. He came to Finley yard and asked her for money. Miss Russell secretly met Charles Kent at Finley Court that night and gave him money. Because she is still a respected housekeeper, she doesn't want others to know about it.
Parker: Parker has a habit of blackmailing his master. He once blackmailed his last master. When he heard the word "blackmail" in the conversation between the doctor and Ackroyd, he felt profitable and continued to eavesdrop, but he didn't hear anything of value.
Ursula Bourne: Ursula Bourne is a living room maid, but she fell in love with Ralph Payton and got married secretly. When she learned that Peyton was engaged to Flora again, she went to Ackroyd to tell the truth and had a big fight. In the evening, she met Ralph in the pavilion in the garden. In order not to arouse suspicion (worry about Ralph), she concealed these things.
