Lucy Worsley takes a look into one of Agatha Christie's biggest mysteries of all, not a book, but the events surrounding her mysterious disappearance.
It's a more intriguing episode than the first, perhaps that's just my interest in her disappearance. I'm not sure we'll ever know exactly what happened to her, despite The Daily Mail article, but a few theories are spun here, Edgar Jones puts forward an interesting theory about Agatha being in a fugue state, personally I've always wondered if she wasn't playing the part as research for a book, I'm sure we will never know.
Plenty of interesting insights into mental health treatments at the time, fortunately methods have developed somewhat.
More fascinating footage and images, it really does transport you back in time. Some amazing, personal issues of Agatha with her family.
One interesting observation Lucy makes, about the change in Poirot, his move from physical clues to a more psychological approach, and that is definitely true in the timeline.
It makes me want to read The Mystery of The Blue Train.
8/10.
