I've always enjoyed Agatha Christie whenever I picked one of her books, though the level fluctuated somewhat. Now I know why this one is held up there with "And then there were none", and it deserves the praise.
The mystery is a good one: closed quarters, and it keeps getting more intricate and tangled with each chapter. This, I expected.
What I did not expect, was the emotional charge. I felt intrigued and amused for most of it.(show spoiler)
I felt awe, kinship and compassion in the end.
So, yeah. Full stars.
