I was licking my lips at this for about 10 seconds until I saw the name Agatha Christie. I'd like to think I kept an open mind, but yes, typical Christie far fetchedness filled the second half of this. I don't think far fetched twists combine well with a courtroom genre. 6/10 for me with a notable mention for Dietrich's crazy (and dubbed) costume change and cockney accent. I knew I was watching something intentionally weird, but didn't even twig that it was her.
