Some questions about the plot...
1. What happened to Dr. Mortimer? Was he in on it too? I don't remember the film showing what happened to him but didn't he help Stapleton try to kill Holmes in the mine? Afterall, it takes two to let go of the buggy since they were both holding it.
2. Why was stapleton's daughter acting so bizarre at the beginning? Running away when people said hi to her and than telling Sir to get away from her and then kiss him?
3. Why was Bishop Franklin initially reluctant to admit to Holmes that he had lost the spider?
4. I also find it funny how Stapleton initially saved Watson's life from the quicksand, yet he turns out to be a murderer.
I haven't read the book yet so please forgive my ignorance.
