No smiles for Tessa in Grantchester...
What do you get if you cross a priest and a detective? Well, in the case of new series Grantchester - an unlikely crime fighting duo! The six part drama starts tonight on ITV and stars James Norton, Robson Green and Tessa Peake Jones.
A far cry from the bubbly Raquel in Only Fools and Horses, Tessa's character Mrs Maguire doesn't smile once in six episodes. She's here today to tell us why this new drama is good it's the only production Robson Green has ever worked on where he didn't change a single word in the script.
