I confess that I had this confused with that great film ‘The Lady Vanishes’ and I didn’t realise this was a play version of the relatively recent film of the same name which starred Emily Blunt.
I overcame my confusion as the play commenced but fortunately didn’t remember ‘who done it’ until that moment when I think we all began to have our suspicions.
Samantha Womack (Eastenders) was very convincing as the drunk protagonist living in a messy flat. A bit too convincing. She really did deserve a standing ovation at the end. We loved her. A stand-out performance.
I had some issues with some unrealistic plot twists, but overall it was a well directed and performed play.
