This series was a charming but, frankly, over-long series of mysteries based around literature. It was entertaining, and I admired how each episode managed to involve some piece of literary history. But at the same time, while the stories were clever, they didn't really need forty-five minutes.
Episode nine, in particular, should win an award for longest exposition. The mystery was revealed after about twenty-five minutes, followed by twenty minutes of slow reaction shots as each tiny aspect of the story was drip-fed to the viewer piece by piece.
Plus AKIRA, in the lead male role, didn't really have much to do except repeat the last line of the previous speaker, or go "Ah!" at moments of high tension. Gouriki Ayame was very good, though, really quite convincing in the role of timid book-keeper but often the best lines went to the supporting cast. In particular, Suzuki Kosuke as the interfering coffee-shop manager, Fujinami.
It was a nice, warm, cosy piece of drama and it certainly captured the feel of a dusty second-hand book shop. And the stories were interesting, and they certainly made me want to go out and read the books they talked about. This, at least, makes it all worthwhile.
