As it's the anniversary of Agatha Christie's the BBC have decided to revive her lesser known characters from the 'Partners in Crime' series of novels and short stories.
Sunday night seems to be the perfect time to put this kind of drama. not only is it well shot but the stories are just about taxing enough to be interesting, while not too demanding. Stretching one novel into two parts seems to be a smart move too.
As for the casting I know David Walliams divided a lot of opinion in the press but to be honest I was surprised by his performance. He brings a lot of warmth to the character and there was real subtlety in what he did.
The real star of the show though for me is Jessica Raine, who shines as Tuppence in every scene she is in. She makes the dynamic between her and Walliams believable and can play both the drama and the comedy of the stories well.
Overall a good addition to Sunday night telly. Long may it continue.
