A few decades ago, a diplomat who'd been to China "updated" some ancient Chinese detective stories and published them. In these stories, a magistrate solves many mysteries at once. In the ancient originals, our hero might solve the mystery by mystical means, but in these more-modern retellings, he uses his brain. Fans abound, and you can find out about as much as these Judge Dee mysteries as you like. I read this book, The Chinese Maze Murders, it was fun... but I don't have as much to say about it as those various other folks on the internet.
