Plot holes - Spoiler Alert
I like the movie but thought it contained a lot of plot holes. For one, it was kind of odd that Mrs. Crosbie had laid out such a meticulous and convincing story for the police but she did a horrible job of pulling together a story to tell her husband about the letter. Someone as devious as she was would have had something much more plausible for him. She knows him and would know exactly what he would be likely to believe.
Another problem is who she killed. I know it was meant to be a crime of passion but given her mindset, I would expect her to find a way to kill the wife instead of the husband. She would have known that the life of a native would have been less regarded by the British system; especially if it was determined she was killed by someone in the white business community.
Mrs. Crosbie's own worker, the head boy, was working with Mrs. Hammond and had full run of the Crosbie home. Mrs. Hammond had been on the property once before, if she wanted to kill Leslie she could have done it or had someone do it without anyone knowing what happened. Why would she demand payment for the letter then turn it over to Leslie so she could be acquitted? In the trial her husband was made to be the bad guy.
Why not release the letter to the court and show she was not what she claimed. His name was already soiled; the letter would not have made it worse. It would have showed he was not a potential rapist as Leslie claimed. What happened is they tried to change some things in the original story but ended up creating plot holes as a result.
In the end, if she knew she would be killed if she stepped out, why did she try to scream and struggle when she saw her head boy standing there with Mrs. Hammond? I realize she probably felt she had no reason to live and may have accepted her fate but her reaction at the moment suggested she did not want to die.
