- Sherlock Holmes: [Referring to a drawing of a building with curves and twists] Your design, is it?
- Malcolm Busquet: It is.
- Sherlock Holmes: Straight lines hurt you as a child?
- Dr. Joan Watson: [Frustrated with having to go through so much paperwork on her own] Did you know that in a building without fire sprinklers, the maximum travel distance to stairwells needs to be 150 feet. But, in a building with sprinklers, it can be 200.
- Sherlock Holmes: Well, it seems rude to make evacuees run an additional 50 feet whilst also getting wet, but I assume that's not your point.
- Sherlock Holmes: Mrs. Graham might not just be a murder *victim*, she might be a murder *weapon* as well.
- Alan Graham: This has all gotten horribly out of hand. Yes, I replaced my mother's arthritis medicine, but I never meant for her to die.
- Captain Thomas Gregson: So you thought she would just float to the sidewalk?
- William Hull: No one killed anyone over this design.
- Sherlock Holmes: You have a particular enemy in mind?
- William Hull: Off the top of my head: other developers that wanted the lot, a steel company I didn't hire once, any of my ex-wives...
- Dr. Joan Watson: So when you said that *we* would look through all the stuff in the city, what you really meant was me.
