- Sherlock Holmes: You went to the vicarage, and you waited there for some time.
- Dr. Leon Sterndale: How do you know that?
- Sherlock Holmes: I followed you.
- Dr. Leon Sterndale: I saw no one!
- Sherlock Holmes: That is what you may expect to see when *I* follow you!
- Sherlock Holmes: [In a depressive stone as he stares at an old grave marker overlooking the sea] Weather-pitted slabs of granite, ancient tombs scattered throughout the length and breadth of this peninsula.
- Dr. John Watson: Like the sea, I suppose, death is always with us.
- Sherlock Holmes: [Holmes stares intently at Watson before answering] Quite so.
- [Holmes is testing out a theory by putting a poison in a lamp, leaving himself and Watson to inhale the fumes]
- [the drug induces a nonsensical but disturbing series of images and distorted memories in Holmes's mind; the images stop and he is outside on the ground]
- Dr. John Watson: Holmes! Holmes! HOLMES!
- [Holmes screams]
- Dr. John Watson: Holmes! HOLMES!
- [Watson has to shout over Holmes's screaming]
- Dr. John Watson: Can you hear me? For God's sake, can you hear me?
- Sherlock Holmes: JOHN!
- Dr. John Watson: Thank God you're alright! That was a stupid and dangerous thing to do... We could have been killed!
- Sherlock Holmes: It was an unjustified experiment even for myself... Doubly so for a friend. I really am extremely sorry.
- [last lines]
- Dr Watson: Not for the first time, Holmes, you've presumed to take the law into your own hands.
- Sherlock Holmes: I have never loved. But if I did, and if the woman I had loved had met with such an end, I might act even as our lawless lion-hunter has done. Wouldn't you?
- Dr Watson: Yes, I suppose so. But that's not the point.
- Sherlock Holmes: The point is: why should I do the work of the official police? And as you're very fond of telling me... I'm on holiday!
- Sherlock Holmes: [In obvious pain from his drug withdrawal, he coughs] To work the brain without sufficient material is like racing an engine - it cracks itself to pieces.
- [He takes a deep breath]
- Sherlock Holmes: Wait for me at the cottage.
- Dr Watson: Where are you going?
- Sherlock Holmes: Cheer up, Watson. Sea air, sunshine, patience!
- [He throws the blanket over his shoulder with characteristic flourish]
- Sherlock Holmes: All will be revealed!
- Dr. Leon Sterndale: [Being interrogated] Within five minutes he died. My god, how he died! But my heart was flint! For what he endured was nothing compared to what my darling had suffered before him! You can take whatever steps you like, Mr Holmes, for there can be no man living who fears death less than I do now.
- [first lines]
- Dr Watson: Almost there.
- Sherlock Holmes: What does a Harley Street specialist know about my health?
- Dr Watson: Listen, Holmes, Dr Moore Agar insists you have a complete rest if you wish to avoid an absolute breakdown. The sea air will do you the world of good.
