(upbeat orchestral music) - Oh, getting a series two was thrilling.

- It was lovely for all of us to find out that we've been recommissioned.

And what is wonderful is that the dynamic and the chemistry are already there.

- It's a great cast.

We've got most of the same crew, same director.

- Coming back this time feels warm and familiar.

When you're on the first series, you're kind of entering the unknown quite a bit.

You're working out what it is, and it's working out what it is.

- What viewers can look forward to in series two is more fun, more joy, more murders, more set pieces of the women doing improbable things.

(car horn honks) (tires screech) - Learn to drive!

- We're catching killers and we're always making sure that there's a glass of champagne at the end of it.

- All mysteries need to be solved, don't they?

- Being reunited with my team, Jo, Cara, and Natalie, it's just lovely.

- It's not just the three of us, it's the four of us women together, and we balance each other out.

We're a really nice mix and we all get on fantastically well.

- It feels like a bit of a sisterhood.

Yeah, definitely.

- Through this series, we see them work closer with the police, so there's less conflict between the police and the super sleuths.

Tanika, who is DS Malik, sort of sees their worth and their value.

They have a lot of fun together.

- Yeah!

- I think it's been really nice to see the journey evolve, that she has a different attitude to getting them on board.

I mean, they're still frustrating, don't get me wrong, I think for Tanika, because sometimes, they seem to always be exactly at the wrong place at the wrong time.

(person screams) - People keep dying in Marlow.

(chuckles) Great.

(Jo laughs) No, that's not so great, but great!

(Jo laughs) We get three sets of killers, three sets of suspects, and also three different writers telling each of the stories.

(camera clicks) - [Judith] This is good!

- Lots of twists.

I love the twists.

- We've got amazing guest stars.

We've got really nice locations.

It's really fun watching the dynamic of the women develop, and I just think it's something that people will enjoy.
