(dramatic music) (knife clangs) - Miss Eliza Scarlet.

- Mr.

Moses Valentine.

- It's just Moses.

I'm very happy to be back.

I've missed being here, miss being, been able to play Moses and just be in the character.

This is a, it's a real privilege to actually have the chance to come back.

You know what I mean?

You don't always get to come back.

- I love Ansu.

We shot only last week the moment where they're reunited.

- I spoke to Ivy or should I say Mrs.

Potts?

- See what happens when you go away?

I could feel the excitement of the audience members in his reveal and it's, yeah, it's lovely.

- So Moses has started his own company is now independently a private investigator, and so he's investigating for people in Paris.

- Ansu is actually a real pleasure to work with.

His process is slightly specific to a certain extent.

And so that always has, he keeps us on our toes and we can't relax with him because he will ask you some question that you're like, "Wait a second, did I think about this or not?"

But he came in super, super ready and it was so much fun and we did a lot of action stuff with him and we did some funny stuff with him and yeah, it was great.

- He's such a joy to work with.

He's a breath of fresh air and he rocked up and he did not disappoint.

He's just superb to work with.

- Feels very different.

Obviously you have Tom, who's new to me and new in a really good way.

And it's also exactly the same because, you know, the main team is all the same people.

You know, for me, the people are the most kind of important thing.

Official story?

That's not what happened?

- That's what we intend to find out.

- Oh, you think perhaps he was murdered?

What makes you think that?

- Well, we can't go into detail.

Not yet, at least.

- I think having Moses back brings an air of excitement to proceedings.

For Blake, it's just quite interesting because so much of the work that he's used to doing himself, he finds that Moses is normally two steps ahead and is delivering ahead of time.

- Mr.

Lawrence rents a legend room in White Chapel.

- Do you have the address?

- Of course he does.

- If I turn up and I see like basically the family that I've not seen for a couple of years, it's just a joyous situation.
