A. Christie is allways good, and the plots follows the books. But they feel a bit like theatre plays. Low budgets, i suspect. But the actors are good, and for Christie lovers it is a must. I hope Tommy and Tuppence will be remade. The stories are worth that.
I know all the Agatha Christie novels pretty well, but have not come across any of the short stories of Tommy and Tuppence 'The affair of the Pink Pear' nor 'Pressng the King' as listed in this collection
