Mai Mochizuki was born and raised in Hokkaido and now lives in Kyoto, and originally wrote Alice in Kyouraku Forest as a series of novels. She's written numerous other titles, including 4th Kyoto Book Award winner Kyoto Teramachi Sanjou no Holmes which was turned into a manga and anime series.
A story within a story. Aigasa has written a murder mystery and wants Holmes and Aoi's opinion and we read the story with those two. The mechanic did not really work for me. It was a decent enough mystery, and the characters are literally the same since Aigasa purposely copied Holmes as the MC. Still, the author tried to change her writing style which takes some time to get used though, and more importantly for me, the mystery is not the main reason for me to read the series. The tourist guide to Kyoto, and the art history are missing. All in all, not the best of the series for me, but if the main draw to Holmes are the mysteries and the characters, then you will probably enjoy this more than I did.
Every volume of Holmes of Kyoto feels like seeing a new work of art. Each one seems to find a new way to move me as a reader.
For the first chapter, I feel the author does a good job of helping me as the reader to understand and identify with the struggles of Kaori and Ensho.
The second chapter then goes into a totally unexpected but extremely fun and creative direction where we get to read one of Kurisu Aigasa's mystery books. It showed a totally different but still fun, intriguing, and endearing side to not only the characters but also to Kyoto itself and Japanese culture. I feel it worked well. It would be nice to read more of Kurisu Aigasa's books in the future.
