I finished 斜め屋敷の犯罪 by Soji Shimada (島田荘司), from the Kiyoshi Mitarai series. It was a really great locked-room mystery in a mansion with a fascinating architecture.
I do prefer murder stories that rely on psychology and motive rather than puzzles and locked-room mysteries, but I enjoyed this one very much. Bonus point for the commentary by Yukito Ayatsuji!
