Luther, Series 1

Alice Morgan:
How do I know you're not playing a double game? One stone, multiple birds, trying to make me speak carelessly in order to entrap me.

DCI Luther:
That would be illegal. Plus I really need to catch this man.

Alice Morgan:
More than you want to catch me?

DCI Luther:
At the moment, yeah. I'm running out of time.

Alice Morgan:
Because if I thought you were about to lose interest in me, I'd be inconsolable.

DCI Luther:
I just need a way in, to know what it's like to be him, to not feel anything.

Alice Morgan:
I feel things.

DCI Luther:
Not mercy.

Alice Morgan:
Not sentiment. I can't empathise for this man's state of being any more than you can, because, disregarding a single, ah, alleged act, carried out for different, alleged, reasons, he and I might just as well be from different species.

DCI Luther:
[sigh] See, I disagree. Murder's murder.

Alice Morgan:
But it isn't, is it? Not even to you. This man Burgess, he's just a naughty child showing off. You already know his flaw - his compulsion to dominate, to be in control - and you already know how to exploit that.

DCI Luther:
How?

Alice Morgan:
Oh, come on. Change the state of play.

DCI Luther:
Yeah, well, I tried that with you and it failed.

Alice Morgan:
Only just.
