Goof: Luther suffers a laceration over his left eye after being hit by Owen's rifle. The wound bleeds profusely. During the scene as the camera switches focus between Luther and Owen the blood and wound almost vanish.
Goof: At the staged crime scene the emergency lights were turned off. When the shooting starts the lights are suddenly on again.
John Luther: The thing about little boys, they worship their dad like God. The more invisible he is, the more arbitrary in his punishments and rewards, the more they crave his approval.
(Luther walks from the crime scene into a cluster of reporters to get to his car.)
John Luther: Morning, Corinne.
Corinne Day: Any suspects, John? Off the record.
(Luther keeps walking past her without comment.)
Corinne Day: You got my number.
John Luther: Yeah, memorized: 666.
Corinne Day: Direct line.
John Luther [ answering his mobile ]: Stop stalking me, Alice, you're yesterday's news.
Alice Morgan: Yes, I heard about the dead policeman. I was worried about you, John.
John Luther: About what, that someone else might get me?
Alice Morgan: I know how hard men like you take the death of fellow officers. Must be like losing family.
John Luther: I'm not discussing cases with you.
Alice Morgan: Not even interesting ones?
John Luther: This isn't interesting, all right? These are good cops, doing good jobs, being gunned on the streets like—
Alice Morgan: Like what? That's something we all do, isn't it, in the end? Judge who's worth more than whom? Hitler or Gandhi? The very young, the very old?
John Luther: Though, to be fair, most of us don't do it to the extent that you do.
Alice Morgan: But it does mean the difference between us is one of degree, not category. Ask Henry Madsen.
John Luther: All right, you win, okay? You're too clever for me, Alice.
Alice Morgan: Flattery to appease a malignant narcissist. That's a frivolous tactic.
Alice Morgan: I've been wondering, why do you think he does it?
Zoe Luther: Why does who do what?
Alice Morgan: John, his job. It takes such a toll. Why does he put himself through it?
Zoe Luther: I don't see how this is relevant?
Alice Morgan: Well, it is. Right this second, you might actually be helping him. What do you think compels him to do it?
Zoe Luther: He believes one life is all we have, life and love. Whoever takes life steals everything.
Alice Morgan: And do you agree?
Zoe Luther: I don't know. I think if he'd read a different book by a different writer at just the right time in his life he'd have been a different man. He'd have been happier as a priest than—
Alice Morgan: Than what?
Zoe Luther: Than what he is.
Alice Morgan [ to Luther on his mobile ]: I've been reading Bertrand Russell to a friend of yours. 'Often, the good suffer and the wicked prosper, and one hardly knows which of those is the more annoying.'
Alice reads to Henry Madsen from Russell's 6 March 1927 speech to the South London branch of the National Secular Society, 'Why I Am Not a Christian.' This jab from 'The Argument for the Remedying of Injustice' section.
