Agatha Christie - Murder on the Orient Express

Chapter 8

This is the final, very long scene of the chapter, which takes place in the lounge car when all of the train passengers are gathered so that Poirot can explain the solution to the case, including all evidence and accusations (the denoument, if you're a mystery novel fan). There are a lot of questions in this scene, and you must answer them all without a mistake. (It's possible that some of the questions may not count toward the achievement, but it's not really worth the risk given the length of the scene.)

These are all of the questions and the correct answers for this achievement:

What was the motive for the crime? Revenge
When was the crime planned? Several months before departure from Istanbul
Who is Daisy's murderer? Ratchett
What do the 12 stabs symbolize? A jury in the United States

The next section has 4 items and you must select them all one by one; there's no single correct answer:

The broken watch
The vaping liquid
The conductor's jacket
