Recovering from amnesia, Dr. Arthur Calgary discovers that he alone could have provided an alibi in a scandalous murder trial. It ended in the conviction of Jacko Argyle. The victim was Jacko's own mother, and to make matters worse, he died in prison. But the young man's innocence means that someone else killed the Argyle matriarch, and would certainly kill again to remain in the shadows. Shaded in the moral ambiguity of murder, the provocative psychological puzzler of guilt, vengeance, and blood secrets is among Agatha Christie's personal favorites.
Aww Calgary got his happy ending. Normally would have been a bit annoyed with how it ended but it was just so sweet. And the mystery made a lot of sense. Rounded up from 4.5 stars because of some weird ideas about adoption but that was the time period I guess.
I've also watched the 2018 movie version and it was widely different. Both the book and the movie are thoroughly enjoyable, but they're significantly different.
