- Detective Superintendent Peter Boyd: [Entering the interrogation room] Mr. Ryan...
- Liam Ryan: Liam, please. I'm only ever called Mister if I'm in trouble. Am I in trouble?
- Detective Superintendent Peter Boyd: [At the shrine] Do you believe in any of this?
- Dr. Grace Foley: Well, I think it's important that people have hope.
- Detective Superintendent Peter Boyd: Yeah, but it's a false hope though, isn't it?
- Dr. Grace Foley: Sometimes it's better to have a little hope rather than no help at all, don't you think?
- Detective Superintendent Peter Boyd: Let's go.
- DC Stella Goodman: Where?
- Detective Superintendent Peter Boyd: To the woods.
- DC Stella Goodman: [Clearly nervous about it] But the dog...
- Dr. Grace Foley: Yes, you want to be careful.
- DC Stella Goodman: Oh, you're not coming?
- Dr. Grace Foley: No, I don't do woods at night.
- Detective Superintendent Peter Boyd: [Investigating Davy McDonagh's death] Do you employ gypsies?
- Sean Killigan Snr: I use Irish lads. Some of them are travelers, yeah.
- Detective Superintendent Peter Boyd: Did he work for you?
- Sean Killigan Snr: You could say 'no', and that might be a lie. The honest answer is I don't know.
- Detective Superintendent Peter Boyd: So that could be a 'yes.'
- Sean Killigan Snr: It could be.
- Dr. Grace Foley: [Speaking of a Celtic symbol] Symbol was painted on the shields and torsos of warriors. It was believed to guarantee rebirth.
- Detective Superintendent Peter Boyd: Didn't work then for Davy then, did it?
- Dr. Grace Foley: Well, obviously not, but what it has done is shown us the world he inhabited at the time of his death. It was steeped in ritual.
- Detective Superintendent Peter Boyd: So, we're looking for an Irish traveler religious sect that sacrifices people in concrete pits.
- Dr. Grace Foley: Please don't go there.
- Detective Superintendent Peter Boyd: Don't you think the nuns did it? I think the nuns did it.
