What an interesting view into a mixed world. The brother/husband as a policeman, perhaps intentionally, doesn't see the world in which he married. The sister – narrator and main character – tries hard to find answers to more and more confusing and inconsistent aspects of her sister-in-law's life. It's unclear as to what the goals of that sister-in-law are, but the glimpses and truths all around her paid a varied and intriguing picture.
The author appears to try to become part of the confusion and intrigue. I liked her particular intriguing take on the whole situation. Interesting book. Not specifically a mystery per se, and although it's listing in Audible is as "history", it really doesn't pretend to be a true history. But I enjoyed it.
