in this chapter there is 1 red herring and 2 hints. 1 hint is related to the creepy old man murder and the previous murder of tateha. the other hint is related to the murder of ruri. light bulb turn on?
obviously the motive must come after the reveal because if it reversed it wont make a good mystery. but i can tell you what the motive of this case; that motive is "butterfly"
So it has nothing to do with the madam's dead lover then? Ah well, I don't really understand the butterfly thing so I'll just wait for the reveal then. Should be soon hopefully.
