(gentle music) - [Man] Why didn't I see it?

Why didn't I do more to help her?

- [Woman] Cass's death was not your fault.

It was just life.

Random, cruel life.

(loud thudding) - [Reporter] The recent discovery of remains found in a house in Hammersmith.

- Morning, ma'am.

- Where's the body part?

My name is DCI Jessica James.

I am aware of the boots that I'm filling.

I don't intend to run this team like she did.

- If there's an exit wound then somewhere there's gonna be a bullet.

- [Jessica] Her friends, her family?

Any criminal associates?

Drugs, money?

- Revenge.

Unpleasant people.

Capable of anything.

- [Man] Would you say violent?

- Yeah, man.

- [Woman] How did they get away with it?

- [Jessica] Bele?

- Yeah?

- Who did you mean they?

- I'm gonna call the boss.

- Which one?

- Did you apply for this job, DI Khan?

- [Man] I don't like her.

- I'll do the talking.

- I'd say it's game on.

- Game on, indeed.

- [Woman] This isn't therapy, DI Khan.

- She's rude.

She's permanently distracted.

Unpleasant to my team.

- Did you guys always work at this pace?

- It takes as long as it takes, ma'am.

I'm dealing with some personal issues.

- Everything's fine.

We have full on jobs that we love.

You knew that was the deal when you married me.

- That's not enough.

- DI Khan.

- [Man] We found blood.

Lots of blood.

- [Woman] How do we prove that he's telling the truth?

- [Man] We need to be in the room together.

We need to talk.

We need to come up with a thousand theories.

- [Woman] I can't be her.

- [Man] I'm not asking you to be.

- Let's reset.

(dramatic music) - [Man] Why do any of us do things we know are wrong?

- What did you do?

- [Man] There's more to that than he's admitting.

- [Woman] Do you want to tell me why?

- I'm not telling you a thing.
