Sherlock Holmes
- Sherlock Holmes: I know all about poisons, Watson. I've become an expert on all of them. But over the last few years, I've come to understand that there is nothing on this earth so toxic as guilt.
- [Holmes and Bell are examining what looks like an empty room in a murder victim's house]
- Sherlock Holmes: We need to find the black light.
- Detective Marcus Bell: What?
- Sherlock Holmes: There's a chemical called CAM phosphor that's all over the walls, smells like burnt matchsticks. Smell it, smell it!
- [Bell does]
- Sherlock Holmes: It's a key ingredient in an ink that only shows up under...
- [he removes the shade from a standing lamp, revealing a black light bulb]
- Sherlock Holmes: Ultraviolet light.
- [He motions to the blinds]
- Detective Marcus Bell: What? Oh.
- [He draws the blinds to darken the room, and Holmes switches on the light, revealing the walls covered, floor to ceiling, in mathematical formulas]
- Detective Marcus Bell: What is it?
- Sherlock Holmes: Well, I'm going to take a very literal stab in the dark and say... maths.
- Sherlock Holmes: You always been this observant?
- [Marcus stares at him]
- Sherlock Holmes: I'm asking that quite sincerely. I was wondering if exposure to my methods had helped you in any way.
- Detective Marcus Bell: Actually, before you came along, I'd never closed a case before; neither had the rest of the department. Most of us were thinking of packing up, leaving, letting the city fend for itself.
- [after Sherlock explains Harlan's background as a mathematician]
- Dr. Joan Watson: And you asked him to help you make sense of the equations that you found in the victim's house, I get that. What I don't get, is why he isn't wearing a shirt.
- Sherlock Holmes: Every great thinker has a process, Watson. In Harlan's case, he doesn't like anything to come between him and the numbers. Knowing your Victorian attitude about such things, I gave him a little bell to ring in case he feels the need to disrobe completely. Having said that, I can't promise he won't sit on the furniture.
