A really good mystery novel by a great Japanese writer. The translation for this book is done pretty well. Nisioisin is notorious for is puns and portmanteaus in Japanese, which don't always translate well to English. I was able to pick out several instances of where the translator had to take creative liberty with the original text, but they weren't jarring or out-of-place, which is refreshing compared to some other translations out there. The characters are all fun and quirky and there is plenty of personality to go around. The locked room mysteries are well laid-out and the resolutions are satisfying. It's also quite long so it's a lot of book for the money, too.
