Can the well-read owner of a rare book shop use her knowledge to solve mysteries? Biblia Koshodou no Jiken Techou (ビブリア古書堂の事件手帖 – Biblia Rare Books Hall Case Files) seeks to answer that question. That owner, Shinokawa Shioriko (Gouriki Ayame) has already used those deductive skills to win an assistant – Goura Daisuke (AKIRA) – and a solve a couple of other mysteries besides.

This episode starts with Daisuke startled by the manager of his favorite cafe – Fujinami Akio (Suzuki Kosuke).

Shinokawa saves him, telling him to prepare for a house call. Apparently, they go to the homes of customers who want to sell their books to appraise them.

Just as they talk about what Shida (Takahashi Katsumi) is up to . . .

Biblia Koshodo no Jiken Techou Ep 04 003

. . . they hear a woman’s scream from outside and find Shida lying injured on the pavement.

After they get him back inside, though, he tells them it was just a hangover.

But was it really? All he can remember from the previous night is that he popped into a bar. Getting drunk and passing out is the logical Occam’s Razor explanation, but certainly not the only one.

Biblia Koshodo no Jiken Techou Ep 04 005

It sure seems there’s more going on, as Shida doesn’t have the paper bag of books he had with him the previous night, and instead finds a receipt in his back pocket. Could he have sold all the books while he was drunk?

Biblia Koshodo no Jiken Techou Ep 04 006

Since the books were collector’s items and he apparently sold them for a pittance, he needs to find the person he sold them to (though I have no idea what he’s going to do at that point – a sale is a sale). Shinokawa’s brother Fumiya (Jesse) points out that Shida doesn’t have the faintest idea where he went or who he met the previous night.

But Shida does have some clues – he was lying on the ground with a gold medal, a star-shaped stamp on his forehead, and a flying squirrel. Sounds like it was a truly wild night for him.

But Shinokawa and Daisuke don’t have time for all that – they’ve got that house call to make.

It’s the sort of house people pay house calls to – a big one which indicates its occupants can afford serious money.

The woman in charge is Tamaoka, and she explains that her father passed away recently and she’s been trying to find a buyer for his books. His study has an electronic coded lock to it, so it’d be quite a surprise if these books weren’t valuable.

Sure enough, Shinokawa is delighted by what she finds – pretty much the full range of classic Japanese poetry and literature.

Biblia Koshodo no Jiken Techou Ep 04 012

But it turns out that Tamaoka has an ulterior motive for calling Shinokawa over – some of the books were stolen recently. Tamaoka heard of Shinokawa’s recent successes solving mysteries and hoped that the book store owner could help with this one.

And I was so glad to hear that – it’s about time Shinokawa started thinking of herself as a bit of a detective, and that people started coming to her for this kind of help. For now, Shinokawa was surprised to hear that she had gained such a reputation.

Tamaoka hands Shinokawa a book by Miyazawa Kenji – one that he had to finance himself and that didn’t sell well. In other words, it’s extremely rare.

Biblia Koshodo no Jiken Techou Ep 04 016

Tamaoka reveals that her father loved this book, and actually had two copies – buying the second copy even though he already had the first one. When Shinokawa asks if that was because the second copy was in better condition, Tamaoka says no – the second copy was dirty and had a faded cover.

Biblia Koshodo no Jiken Techou Ep 04 018Biblia Koshodo no Jiken Techou Ep 04 019

But Tamaoka eventually became attached to that second copy – either in spite of or because of its condition – and that’s the copy that was stolen. Tamaoka is sure the culprit who stole the book is someone in her own family, which is why she didn’t want to call the police.

Tamaoka says that her brother and sister are trying to get more than their share of the inheritance. They got their father’s company while she got the house and books.

Biblia Koshodo no Jiken Techou Ep 04 022Biblia Koshodo no Jiken Techou Ep 04 023

It was right after a visit from them that she noticed the book was gone.

Biblia Koshodo no Jiken Techou Ep 04 024

Interestingly, Shinokawa asked about what they were wearing, and why they might pass up on the other books in the study.

Biblia Koshodo no Jiken Techou Ep 04 025

With no other leads, Shinokawa and Daisuke head to the company Tamaoka’s brother and sister control – Tamaoka Sports.

Biblia Koshodo no Jiken Techou Ep 04 027

The brother, Ichiro, is there, and he quotes from the book from memory to show that he understands the emotional attachment to it, and therefore wouldn’t steal it (at least, not to sell it). He tries to lay the blame on his other sister – Sayuri. Not exactly the tightest family, but I guess inheritance squabbles will do that. He says Sayuri hated books.

Later, at the cafe, Shinokawa says she believed Ichiro’s story – to Daisuke’s complete disbelief. The lines that he quoted from Miyazawa’s book were changed since the first edition, and he quoted the first edition version. I’m not sure that’s really sufficient evidence of his honesty, but the opposite situation – where he failed to correctly quote the book he was supposedly emotionally attached to – would have been damning.
