(gentle upbeat music) - So in terms of locations, we are in new places again, which has been brilliant.
The first story is around the Marlow Council Chamber.
And there's also a beautiful garden that has lots of wild, very interesting plants growing in it.
We've got a murder in a sort of high-end farm-to-fork foraged restaurant on the river.
- There was one particular location that we used for one of our storylines, and it was an enormous house that had lots of secret passageways and lots of taxidermy animals and kind of imposing, enormous paintings.
(gentle upbeat music continues) I have to say, of all of the locations we've had, I think I found that the kind of spookiest.
(gentle suspenseful music) - We were filming in the High Street the other week in Marlow, and seeing all of the town go about their business.
It was just magical.
You know, this is a real show set in a real town, and that's really what it looks like.
- People of Marlow are so kind to us.
People talk to us in coffee shops and restaurants.
The vibe seems to be very positive about having us, and we know we sort of descend and take over Marlow for the summer.
So we are very grateful to everybody.
- This series continues to resonate with audiences because there's always a deep intrigue with whodunnits.
And also exploring the idea that everybody's got a dark side.
I think that's a really appealing prospect for people.
- This series, it really feels that we've had a really good run at it.
We've had good weather.
I think the scripts are great.
The actors are great.
Our directors are great.
All of the heads of department are amazing.
This is a superb series that I'm super-duper proud of.
