I have mixed feeling about this book: Winged Darkness: The Last Case of The Remarkable Detective.
Again, I got mind-fucked by this author at the very end of the story. To be more particular, basically this book and its ending is mind fuck, mind fuck, more mind fuck. I felt like I was going to die when I turned the very last page.
I do like the explanation for the murderer's motives and how some of the characters met their untimely death. I dare say hardly anyone else has come up with explanation such as this yet!
Hmm, it takes a lot to digest a mystery like this. I ultimately did not like it and would give it a 1/5, but I'll bump it slightly because the translation I read was rough, which definitely might've hurt the experience. Lots to breakdown, so I'll explain, starting with a spoiler-filled summary.
The narrator (who is a Watson) and his detective Kisarazu, come to Blue Raven Castle (run by the Imakagami family) to solve a case. Kisarazu got an invite alongside a threat to not come, so of course he comes to find out who sent the threat and why. This is followed by several beheadings, including one in a locked room and an initial double one with the heads/bodies in reversed rooms, followed by Kisarazu making a deduction at the halfway point that the oldest male patriarch was still alive. But exhuming his coffin shows he's been deceased for about 30 days. Kisarazu leaves in disgrace to the mountains, and the great detective Mercator Ayu arrives at the start of the second half.
Not too dissimilar to the first half, more beheadings ensure. Ayu similarly reaches a far-fetched conclusion deducing Kisarazu being the ultimate culprit. At the end of his explanation, Kisarazu returns and denies being related the Imakagami, which was the whole motive Ayu gave. Toward the end, Mercator's head is beheaded and Kisarazu explains about the case.
Each of the beheadings had an item left nearby. Ex powder, orange seeds (scattered from a whole in the locked room's door), a hat, an American album, one in the 30 day coffin, etc...these are revealed to be references to Ellery Queen's nationality item books: American Gun, Chinese Orange, Roman Hat, Greek Coffin, etc. It culminates in a dead Sugahiko on a cross in the church (Eqyptian Cross), and his daughter Kyrie (the "culprit") beheaded by gulliotine. Kisarazu says the motive was partly insanity - Kyrie wanted to deify her father by having him/her be the last Imakagami family and then putting him on a cross as a reference to Jesus, then her own demise, purifying them in death.
Then this false solution is overturned by the Watson when he enters a secret passage to an underground jail, where he confronts the true culprit, the maid Hisa, who is revealed to be Sugahiko's grandmother and almost ninety years old. She was Russian and fled Russia for political/other reasons and married a Japanese man and started the Imakagami family. But she felt she was impure, mingling her Russian blood with the yellow Japanese and wanted to cleanse them all by murdering her descendents. For a long time, she held off because she was still a mother, but eventually someone else (a Russian composer I believe) was found who would lead eventually back to the Imakagami Family.
After this revelation, the narrator leaves to marry one of the females of the family (an adopted daughter, she didn't share the Russian blood), and it is suggested that the old culprit commits suicide. Hisa/Kinuyo the old lady culprit also sent the original invitation to the detective as well as the threatening letter, as she knew it would entice him to come. She knew the detective would read into the fake clues she planted and arrive at the false solution. (Later, she invited the detective Mercator, since Mercator was also related, and she wanted to purge him too.)
Trick-wise, a lot of swaps were used. Hisa claimed to get the key from a dusty box to open the locked room that had the bodies. But the thing wasn't actually dusty, it was just a duplicate key. Similarly, a head was seen in a room belonging to Unebi. In reality, it was Tajima (Unebi's father)'s head, and Hisa/another guy discovered it. Hisa pretended to faint while the other guy got help and Hisa swapped Unebi/Tajima's heads. There's also some false solutions like having an accomplice and a woman carrying a head upstairs in her skirt, etc. Hisa also intentionally left clues suggesting the culprit couldn't read Japanese, like leaving a letter or writing an invitation to the twin children in very simple English, which all pointed to Kyrie who had been in America until a few months ago.
There's also some mindfucky twists, like the narrator being Hisa's granddaughter and being the twin brother of Mercator. All of this is actually clued at least to some extent as Kisarazu mentions to the main character that he looks similar, and there's discussion of the Russian composer, etc.
============
Alright, now that the summary is out of the way, my own opinion is that this isn't a particularly good mystery. I think some of the logical jumps for the false solutions sucked. False solutions should be believable and reasonable, not incredulous.
Mercator says Kisarazu was the one to throw the head to the upper floor, for his accomplice Sugahiko. But that could be anyone throwing the head up. The idea that Kisarazu is the first to discover the key in the left hand and hence placed it is plausible, but it is equally plausible there's a duplicate key, which is the true solution and is just bland. (This idea is referenced by the detective near the start of the case, but he dismisses it for no reason whatsoever.)
Similarly, Kisarazu's false solution has Kyrie cut off Ito/Arima's heads at the same point, so close together that the nerves of each body interlink by chance. So Ito in Arima's body and Arima in Ito's body happens, and the one left-handed guy runs to the side room to escape the weaponed attacker, locks the door, and passes away. It doesn't mention how the head got on the coat rack hook at all by the way, and it acknowledges this is a one in billions chance for this solution and is unlikely (I'm fairly certain this is BS science anyway). Similarly, there's not really any evidence that Kyrie would want to deify her father or is that crazy.
Then the true solution. I actually DID clue in on how it discussed that Hisa's head looked like a different person. But I didn't know WHO it was, as the idea that Hisa/Kinuyo kept her daughter in a hidden jail for 20 years is very hard to believe. Then she murdered that daughter and substituted the body is just insane. It's 20 years of imprisonment, and she was 90+ years old to be doing all these beheading stunts, getting the jump on everyone, plus cleaning up all the blood that would splatter on herslef.
It felt like the novel was going for shock value more than actual quality at times, especially toward the end. That shock may have worked, but I sure as hell don't like that. I'd prefer a more complete, plausible mystery that isn't so farfetched. Some of the solutions are also pretty bland, like basic "duplicate key", and I don't love the motive either honestly. There's not much we can know to tell that Hisa is a racist against her own family's people. There's definitely things that suggest the Russian connection like the CD/LD/etc and the red carpet, so I do appreciate that, but still, the mystery focused on shock than quality.
The Ellery Queen book references are a neat idea, but that also requires the reader to know EQ's titles. The narrator reads Dutch Shoe, but otherwise, I don't like requiring that knowledge since it's not as well known as, say, children's tales.
The writing itself was eh, and I suspect it's not just because of the translation. A lot of Japanese and Golden Age mysteries are dry, and even shin-honkaku ones from the 80s/90s tend to often be as well. Then I don't care for the characters either - ex, I didn't even realized the main character cared that much about Yugao until it talks about him proposing/marrying her. Yeah, it was partly for the inheritance, but I don't like mysteries that shoehorn marriages/romance in.
I probably have some other nitpicks, and there's definitely some uninteresting sections, but I think that's most of it. Overall, not a mystery I particularly care for. The things I look for in a mystery are to a) well written b) fair play c) hopefully wow me in terms of deduction/impossible crime. This at most scratches just b), and some of the fair play is questionable. And the false solutions are just a waste of time given how dumb they are.
