Actress Jane Wilkinson is married to Lord Edgware, but she wants a divorce as soon as possible so she can marry again. Wilkinson asks Poirot to help her convince Lord Edgware to give her a divorce, otherwise she will go to his house and kill him. Things get complicated when Poirot realises Lord Edgware agrees with the divorce, but is still murdered that night.

I enjoyed this story because it is very different from the usual murder plot. We know how the murder will be executed from early on, but the obvious culprit has an alibi, which makes the reader look for other options. Having said that, I think it is easier to understand who did what because of that.
