- Sherlock Holmes: What a lovely thing a rose is. There is nothing in which deduction is so necessary as in religion. It can be built up as an exact science by the reasoner. Our highest assurance of the goodness of Providence seems to me to rest in the flowers. It is only goodness which gives extras, and so I say again we have much to hope for from the flowers.
- Dr. John Watson: Come along, Holmes, that bandage tells of adventures. Now what happened?
- Sherlock Holmes: After breakfast, my dear Watson. Remember I have breathed thirty miles of Surrey air this morning.
- Annie Harrison: You suspect someone?
- Sherlock Holmes: I suspect... myself.
- Annie Harrison: What?
- Sherlock Holmes: Of coming to conclusions too rapidly.
- Inspector Forbes: I know about your methods. You're ready enough to use our information, then you try and finish the case yourself and bring discredit on us.
- Sherlock Holmes: On the contrary. In my last 53 cases, my name has appeared in only four and the police have the credit in 49. I don't blame you for not knowing this. You are young and inexperienced. But if you wish to get on in your duties, you will work with me and not against me!
- Dr. John Watson: But Holmes, we can hardly suppose that the thief took the treaty in order to frame it and hang it on his wall.
- Mrs. Hudson: [referring to the recovered Naval treaty] A "Scotswoman's breakfast" indeed! A silly bit of paper!
- [Contriving an excuse for Percy Phelps to leave his country home, Holmes reunites with Phelps and Dr. Watson the next morning at 221B Baker Street]
- Dr. John Watson: [noticing Holmes' bandaged hand] Holmes! You're wounded!
- Sherlock Holmes: Oh, it's only a scratch through my own clumsiness. Good morning, Mr. Phelps, This case of yours is certainly one of the darkest I have ever investigated.
