[Morse wonders whether Dr Martin would have killed Barrie if the police hadn't intervened. She holds up a ring which belonged to one of his other rape victims]
Dr. Esther Martin: When you find the owner of this ring, tell her what I did. You'll find the answer to your question there.
[Strange wonders what sort of texts Heironymous St John's shop sells. To Morse's amazement, Lewis shows off his newly-acquired knowledge of the Occult]
Detective Sergeant Lewis: [glibly] Oh, exegeses on ancient grimoires, I should think, sir.
[Sergeant Brenner brags about his undercover abilities]
Sergeant Brenner: I, personally, can be buried in a hole in the ground for up to three days.
John Peter Barrie: [Contemptuously to the Canon as he plays the church organ] You play like a man with ten thumbs, Priest!
John Peter Barrie: [Contemptuously from the shadows to the Canon] Did I frighten you, Shaman? It's only a shadow, you fat fool. A parlor trick!
Detective Sergeant Lewis: [Speaking of Barrie] How can someone so bright believe in all that stuff?
Canon Humphrey Appleton: I believe in an historical figure who made the lame walk and the blind see, and who raised himself up from the dead, or don't you believe that, Sergeant?
Chief Inspector Morse: We're about to enter the Third Millennium, Canon.
Canon Humphrey Appleton: Yes, but the occult will always be with us, Chief Inspector. It reflects a part of our nature.
Dr. Esther Martin: I really did try to understand Barrie. But... being so near him in the hospital, all that time... I thought I'd go mad. Perhaps I did. Because at some point, I'd decided to kill him.
Chief Inspector Morse: And Barrie himself provided the method, with his obsession about betrayal?
Dr. Esther Martin: Yes. When I told him about the dreams, he said if I was really Ashtoreth's medium, I could tell him who betrayed him. So, I described my own ordeal, and I told him he'd been betrayed by the other man. Then he said if I was Ashtoreth's medium, I could get him out of the hospital. So, I began to see a way that I could pay them both back. It was as thought we were locked together in some absurd game, each driven by our own hatred. The rest you know, Chief Inspector.
