Discussion Guidelines

Spoiler Courtesy

Please follow these rules to avoid inadvertent ネタバレ. If you’re unsure whether something should have a spoiler tag, err on the side of using one.

  1. Any potential spoiler for the current week’s reading need only be covered by a spoiler tag. Predictions and conjecture made by somebody who has not read ahead still falls into this category.
  2. Any potential spoilers for external sources need to be covered by a spoiler tag and include a label (outside of the spoiler tag) of what might be spoiled. These include but are not limited to: other book club picks, other books, games, movies, anime, etc. I recommend also tagging the severity of the spoiler (for example, I may still look at minor spoilers for something that I don’t intend to read soon).
  3. Any information from later in the book than the current week’s reading (including trigger warnings that haven’t yet manifested) needs to be hidden by spoiler tags and labeled as coming from later sections.
Instructions for Spoiler Tags

Click the cog above the text box and use either the “Hide Details” or “Blur Spoiler” options. The text which says “This text will be hidden” should be replaced with what you are wishing to write. In the case of “Hide Details”, the section in the brackets that is labelled “Summary” can be replaced with whatever you like also (i.e, [details=”Chapter 1, Pg. 1”]).

Hide Details results in the dropdown box like below:

Example

This is an example of the “Hide Details” option.

The “Blur Spoiler” option will simply blur the text it surrounds.

I woke up in the middle of the night and couldn’t fall back to sleep so I decided to read a bit and I got to the 閂 explanation and now I’m so mad that I’ll never sleep again.

I’m suing.

I couldn’t stop reading and I’m already done!

So, let’s go over this:

I liked the way 月夜 went over the first murder and addressed a bunch of hypotheticals I didn’t think about because we already knew what happened there. Like what if the murderer hid in the exhibition room? The exchanges with Kuruma were pretty good and thorough.

For the third murder, I had noticed that 加々見’s room was above the victim’s, so I thought he could maybe have used a rope to climb down and go through the window. I thought it was too goofy to be the explanation however. I’m not sure that the actual explanation is much more realistic though? Why not just leave the body in the kitchen or whatever? I guess it makes for a fun story, so I’ll allow it. I suppose all these lines where the narrator kept telling us that rooms were a quarter turn away from each other was building up to this.

The second murder thing is absolute garbage that makes no sense and I hate it.

Also who pushed 遊馬 down the stairs? Is it 加々見? Why? His room was at the top of the staircase, why not hide in there? And what about the dancing figures?

What if you were reading along with the book club but ended up reading ahead and have now finished the book already? It doesn’t feel like that wording quite fits. Asking for a friend >_>

Impressive! But what are you going to do with your life until next week now? :thinking:

Haha oops. I guess I could add an option “I’ve read this part ahead of the club”.
I could also simplify and remove either “I will catch up later” or “I’m still reading the book but I haven’t reached this part yet”, they are pretty much the same thing..

Wow, I expected something like this for Kuruma because he knows a lot about mysteries, but I was completely in believe that Kagami knows nothing about them! But it all makes sense and I’m happy with the revelations.

But indeed, we still need explanations about dancing figures and who and why pushed Yuma.

Also last time I said that I hope he would get away with it, but he feels so not smart, that I would be shocked if Tsukiyo doesn’t catch him. Especially after this pill case action.

Yeah 遊馬 deserves to be caught at this point.

Oh boy. This week was certainly a ride. I have so many thoughts and things I want to say. Let’s see if I can bring them in an understandable format:

When she retraced the steps of 遊馬s murder, I thought to myself, man, this is real accurate. I liked the chapter being sort of a recap over all. I’m not normally reading much detective fiction, but I feel the genre has great pacing because of these “reveal” chapters.
I liked the explanation of the ash being the indication that the key wasn’t there from the beginning.
But after the explanation that fit perfectly, I was half expecting the author to pull the rug out of under us and the explanations for the other 2 murders to be false leads :frowning: .

I so feel you. First, I remember 遊馬 proposed something really similar to this and 月夜 dismissed it. Second, how many fucking centimeters are behind the moving piece? A sugar cube has quite the volume.

At least the fire start was similar to what I envisioned. I didn’t think the blood writing had any effect, but instead thought that maybe a glass or similar, from setting up the table for breakfast, was used to focus the light even more and start the fire with the 綿毛.

But what I couldn’t live even more with was the explanation for the third murder. You want to make me believe that after the fire alarm started, he lifted the dead body out of a window that was 45 degrees tilted at the top? And the body then slips perfectly down? I made a picture to show how I think you “could” possible throw the body out.

window191×153 528 Bytes

But given this picture, you wouldn’t be able to hit the window directly below! And even if you did, the body would just land folded up in a pile instead of spread out on the bed like the text let me believe when they found her :frowning:
And lifting the body out of the window takes time and a lot of energy. So afterward, he sprinted to the first floor and was faster there than other people (I had a look back, and he arrived second).
I find that all a little too unbelievable.

What I did like was his motive. It ties the story back to the other stories and makes sense in my eyes. That the police station didn’t want to to investigate just because of a hunch is also relatable.

What doesn’t make much sense is that he always feigned not knowing anything about mystery novels? He did it from the beginning and according to his own testimony he only took the chance to kill the other two after the first murder had already happened… So why did he have any need to hide this passion?

Also, we finally have definite proof that the pill case still had poison in it. I’m happy I got that one right. But oh boy, that death was horrendous to read. Not something that I wished on 加々見.
That reminds me, somebody in the beginning said the names are strange and 加々見=鏡. Well played, realizing it so early. But the connection to her being his daughter was something so 月夜 and a bit out of left field.

Still not at the point of the prologue. But given everything that happened, it wouldn’t surprise me if 月夜 would realize her mistake for the first murder.

Also, what is up with Japanese and their bug obsession? 虫眼鏡、苦虫を噛み潰しように o_O

Looking forward to what other people thought of this week…

EDIT: Oh, I forgot to write it. But I was also a little disappointed by him only having a hunch that they are involved. I was hoping for something more substantial. I mean, he murdered oita and tortured madoka without having proof. Puuhh, hard pill to swallow. All the people in the story I wouldn’t want to be friends with…

The third murders gets points for creativity so I’m willing to forgive the goofiness of the scenario, but the second is just complete nonsense for me.

The first crime had to be a 密室, it was integral to the plan in order to make it look like an accident or possibly a suicide and not raise suspicion.

The third crime was effectively an accidental 密室: he didn’t know where the key was and needed to get the body out of his room one way or another.

But the second one? Even ignoring the absurdity of the “trick”, what was the point? If he had just killed the butler and left immediately, what would be the difference? Taking the time to stage all that and risk being discovered by somebody randomly entering the dining room for no discernible gain.

Week 8

The second murder explained was not very surprising to me. I had seen the trick with the sugar in Ninzaburo (in hindsight maybe I could have thought about it, since it was obvious that water had been used to make something disappear), and the trick with the light we also figured out.

However I really wasn’t expecting the explaination for 巴’s murder. The fact that she landed on the bed in the way that doesn’t show that she just landed from the window is a bit hard to believe (and also, lucky that the speed didn’t pick up and that she didn’t go crashing on the ground), but otherwise great reveal.

Also the fact that “pearl” in greek is said “margaritari”, and mirror = ミラー = Millar were really WTF. I, the reader, would have never guessed that in a million year. But maybe a mystery novel fan, knowing the name Margaret Millar, would have managed to find that connection? I wonder though, why on earth 加々見 and 月夜 would know any greek.

There’s definitely more stuff to come, after all this wasn’t the last chapter. We don’t even know if 加々見 was the one putting the dancing figures there (beyond not knowing what they mean)

The same trick was also used in Ninzaburo to prove that someone was killed and didn’t commit suicide (spoilers on that Ninzaburo episode: someone was killed at their desk, and the gunshot made paper from a stack on the desk flow on the ground. The killer put a critical object on the pile of paper, not noticing the few pages that flew on the floor, so the detective figured out that the object was put down after the person died).
So if anyone wants to commit a murder one day (or write about one), take notes, you should always check what is under what you put down on the crime scene.

I like your point but not sure it stands. My understanding is that the top part of the window opens automatically, but maybe he can just open the bottom part of the window normally? Also Japanese women are not that heavy, according to my serious research from reading manga:

It’s 加々見 by the way :stuck_out_tongue: but 加々美 would have been great for a lady’s name

I wonder if there’s more. They haven’t talked about the taser gun. Maybe he had a friendly talk with 老田 first and tried to get some info out of him. Then framed it as a mystery murder so that 巴 wouldn’t be tipped of that he was after them (though I think writing 蝶ヶ岳神隠し would definitely tip her off, so I don’t know)

Fixed :smiley:. My IME isn’t the best for names and if I don’t concentrate stuff like that happens ^^
And thanks for your views on the murders.

Just a few pages in this week, but I went back and looked at the prologue again, and it’s pretty explicit about Yuma being the criminal who was exposed. So I guess Tsukiyo won’t pin it on a third person, but she could have framed Yuma for all 3 murders (especially since in this chapter she referred to one culprit that’s killed 3 people).

This week

Aha, so when 加々見 followed 巴 to her room in the earlier chapters it was for the murder! And that explains why it felt like he was so harsh to her when 老田 died - he clearly already knew she was involved.

I was dying at the scene where he just drops the pill case into 加々見’s coat. I can’t believe that actually worked, come on! And no one saw?!

I really doubt it was him, he was quite clear on wanting to have been the one to finish off 神津島 but not having done it… I doubt he would have gone as far as to revisit the corpse after all that.

I definitely think there’s definitely something more to both 老田 and 巴’s murder. Also the fact that 月夜 hasn’t mentioned either the taser nor the figures/knife on 神津島 is really suspicious. And, of course, whoever pushed 遊馬 down the stairs.

Btw, I have to admire 酒泉’s single-mindedness. Sure, you’re pissed that 加々見 killed 巴, but did you just forget the fact that she’s also a criminal responsible for torturing and assisting in performing human experiments? Come on my dude :sweat_smile:
