- DS James Hathaway: Not if you just read them.
- Ch. Supt. Innocent: [to Lewis and Hathaway] Why are you just sitting there looking at me like dogs being shown a card trick?
- Myra Barnet: [Hathaway's cell phone rings] Wouldn't it be Courteous to have that thing turned off!
- DS James Hathaway: I'm at work, not at the theatre.

- DI Robert Lewis: You wouldn't have anything for a bad tooth in here, would you?
- Dr. Laura Hobson: I could take it out for you if you like... Course, you'd have to be dead first!
- DS James Hathaway: [referring to Adam] He's like the three wise monkeys rolled into one bloody-minded urban guerrilla.
- Myra Barnet: [answering her front door] If you're double glazing, I don't want it; Jehovah's Witness, I don't need it; changing my gas supplier, you're all as crooked as each other so, all in all, it's a general "no thanks"
- DI Robert Lewis: [displaying their badges] We're the police.
