I must have missed the start of episode 2 because suddenly the 3 women were no longer members of the public but civilian assistants (is there such a thing?)
It was all improbable but easy watching and I didn't guess the plot at all!
I had thought it was an Acorn series but searched and found it was co-produced by Masterpiece (whoever they are) and UKTV as beomg released in 2024. Quite a few new series do get shown on UKTV first (Drama is just one of their channels). I think Annika was.
The ad breaks seemed a bit longer in the last episode, but maybe that was in response to good audience ratings.
On a totally trivial note (and have got side tracked in other series by this) but many of the women looked like they had dived through a hedge backwards and / or didn't know what a comb was! And then had it gelled into place.
Apparently there is talk of a series 2.
