Dr. Stapleton
- Dr. John Watson: [about Sherlock's "mind palace"] It's a memory technique. A sort of mental map. You plot a-a-a map with a location. It doesn't have to be a real place. And then you deposit memories there. That, theoretically, you can never forget anything. All you have to do is find your way back to it.
- Dr. Stapleton: So this imaginary location could be anything. A house or a street?
- Dr. John Watson: Yeah.
- Dr. Stapleton: But, he said palace. He said it was a palace.
- Dr. John Watson: Yeah, well, he would, wouldn't he?
- Dr. Stapleton: Oh, back again? What's on your mind this time?
- Sherlock Holmes: Murder, Dr. Stapleton. Refined, cold-blooded murder.
