- Edwyn Cooper: Caesar's wife.
- Young Policeman Jack: Sorry, sir?
- Edwyn Cooper: Caesar's wife must be above suspicion. You don't know your classics?
- Young Policeman Jack: Not, like, off by heart.
- Edwyn Cooper: Envy, temptation, greed. Human nature is weak and that is why the law must be strong. And that is why those who propagate the law must be strongest of all. For a civilised society to operate, Caesar's wife must be above suspicion.
- Young Policeman Jack: Oh, OK, right. Yeah, I get it.
- Edwyn Cooper: As a solicitor, I've represented 42 police officers accused of corruption and I'm yet to lose. And that is because I don't represent bent cops. I represent those who have shown weakness and are ready to repent. I keep good men on the beat. Are you a good man?
- Young Policeman Jack: Yes, I am, Mr Cooper.
- Edwyn Cooper: You accepted a bribe.
- Young Policeman Jack: I didn't take it.
- Edwyn Cooper: So we're in the grey. You accepted it but never took it. They will try and argue from the grey to the black. I will argue from the grey to the white and I will win. And I will get you back on the beat. And when you are back on the beat, Constable, pounding the troubled streets of this once great city, you will think of Caesar's wife.
- Young Policeman Jack: Yes, sir.
- Brian Boyce: I did 20 years in London, from the beat to criminal intelligence. I've nicked every villain in this city once and the good ones twice.
- Assistant Commissioner Gordon Stewart: That's why you're here.
- Brian Boyce: I don't want to be wondering which of my team are Masons, which are on the take and which are both. Which means I don't want Flying Squad and is why they won't want me.
- Edwyn Cooper: What is this farrago, George? Come here. Always look the part. The world decides who you are from what you show them.
