This week spoiler

So we have another suspect called mr. T who isn’t the three-finger man, the bridge of the koto was found into 隠居さん’s kimono sleeve and small message in the cat grave. The end seems close. I still have no idea what’s could have happened during both crimes.



My current theory is:

The koto playing was accomplished by manipulating the thread of the koto with some mechanism - this mechanism or getting rid of the evidence caused the thread to break and a kotoji to come loose. Probably this was used to connect another thread? To the outside. The scratching sound as well can be explained by a semi random movement caused by this trick. The sword getting outside could be accomplished by such a trick as well.
The most suspicious imo right now are 糸子, 隆二, 三郎 (though I’m almost sure 三郎 is at most playing detective in his own right, and that his incident was a copycat thing), and I’m not sure at all what role 田谷 plays in all this. 金田一’s question to the lady at the tabacco shop seems to indicate that the 3 fingered man may have been simply a suspicious looking but innocent guy on his way past the village, used as a convenient scapegoat by whoever orchestrated the crime. I wonder if they’ll actually find someone who matches the new fingerprints.

Please keep in mind I’m no detective. :joy:


Not sure it’s a message, it sounds more like an object but it’s not very clear. We’ll find out soon I guess.

I personally have no clue about anything but I like it this way! I’m quite enjoying the book.
