Jukkakukan no Satsujin
couldn't believe ellery died... he was set up like the main character, but then he also died.... sigh. i have to admit, the trick was brilliant, and the mangaka utilized the advantage of manga format, readers's dismissive attention to details, and a bunch of red herrings to pull the wool over our eyes. the storytelling/panelling is pretty simplistic but the art is really gorgeous. the motive ended up kinda cliche, but the reveal that it was all for nothing made it even more bitter and sad. it'll probably torment him forever.

holy shit that plot twist on ch 37 rendered me breathless. did not need to feel sadder than i already did for those two. it also finally gives a rough timeline of both settings.
