- You know what I think?

- I think we can guess.

- It's our civic duty to help the police in every way we can.

- When we open series three, we find our three sleuths in a good place, that their relationship has obviously moved on.

- Their friendship is so solid now.

Here we go.

- What?

- It's not Tanika.

- Oh.

- What?

- And they know each other so well that we give each other confidence to shine, you know, to believe in oneself.

- Come on.

Sophia is not the only person who needs to be somewhere else.

- Of course, your afternoon tea with Darius.

- You're getting nearer to that nightcap.

One meal at a time.

- Oh, stop it, the pair of you.

- As far as the relationship with the three main amateur sleuths with our one professional sleuth, that being Tanika this is the series where they all, and not just Tanika, but Brendan and Jason and Alice, they all begin to appreciate each other's qualities.

- We could help if you liked.

- Get some food in, make a night of it.

Bosh, get the job done.

- That would be amazing.

- There's a joy in terms of seeing them and also an acceptance of they're really useful.

I don't feel ashamed in terms of having them as part of my gang.

- Because we do, the three of us do achieve, I think Tanika has learned to put her trust and faith in us.

- We keep eyes on all our suspects, see who they talk to, let it play out.

There's the occasional eye roll from Brendan, but on the whole, yeah, we're very much a united team.

- Eyes on our key suspects at all times.

(light dramatic music) - That is a lot of money.

- And what drives them on is trying to get to the truth of a situation.

It seems you lied to the police.

And trying to achieve justice.

Oh, that's very clever.

I think I know who the killer is.
