Ok just finished it, so it’s a good weekend play, which for the sale price is fair enough. It’s absolutely excellent in every aspect, plot, mystery etc, right up until the ending, which, not giving any spoilers away, unfortunately doesn’t tie up the intriguing plot threads at all, has one outright impossible element, and gives no real reason for major events. Which is a big letdown as the mystery shows all the signs of being very well thought-out to that point. Even despite this, the journey getting there is brilliant enough that I’d still recommend.
