- Dr. John Watson: I was certainly surprised to see you in that place,
- Sherlock Holmes: I suppose you think I've added opium smoking to all my other little weaknesses?
- Dr. John Watson: [awaking in bed after Holmes has tickled his foot] What time is it?
- Sherlock Holmes: Dawn.
- Dr. John Watson: Uh... I've only had two hours sleep.
- Sherlock Holmes: I wonder if you'd do me the very great kindness of considering the possibility of waking up.
- Dr. John Watson: I... I assume you have a good reason.
- Sherlock Holmes: Are you game for a drive?
- Dr. John Watson: Certainly, but does it have to be this early?
- Sherlock Holmes: I have a little theory I wish to test.
- Dr. John Watson: Is anyone's life at stake?
- Sherlock Holmes: Certainly not!
- Dr. John Watson: Would it be possible to test your theory a little later this morning?
- Sherlock Holmes: [leaving to go downstairs] I'll see you downstairs in five minutes.
- Dr. John Watson: Five minutes.
- [sighs and lies back]
- Sherlock Holmes: [in flashback, at the police station] Inspector, with your permission, may I suggest an alternative strategy? Let me visit the opium den. Discreetly. Incognito. We shall learn what we may!
- Dr. John Watson: [back at The Cedars] But what did you learn?
- Sherlock Holmes: Nothing.
- Dr. John Watson: It's now well past four in the morning. May I go to sleep?
- Sherlock Holmes: Certainly.
- Dr. John Watson: Thank you.
- Dr. John Watson: Mr Holmes has disappeared without trace, as you can see.
- Mrs. Whitney: In that case, I really shouldn't bother you with my problems.
- Dr. John Watson: Oh, Mr Holmes disappears without trace at regular intervals. There's really no cause for alarm, only curiosity.

- Neville St Clair: Farewell, sweet Boone; a flight of angels sing thee to thy rest. William Shakespeare.
- Mrs Hudson: And what should I tell Mr. Holmes, should he return?
- Dr. John Watson: Tell him I have disappeared without trace.
- Dr. John Watson: May I ask why I'm going to Lee in Kent, in the middle of the night on a Friday in March?
- Sherlock Holmes: Because you are my trusted comrade and my loyal chronicler. I may need both.
