Im very disappointed with the resolution.
You expect me to believe that a student got up front heir chair, up the stage, moved the dummy and recreated the crime scene, all in total darkness (while using only one eye, to boot), then went down back to their seat, in like, less than a few minutes, without making any noise and nobody noticing anything?
Man, Japan loves to make these Sherlockian series, but they rarely ever manage to pull the proper cases with good tricks and solid logic to back the story up.
I guess I can give it a few more chapters to redeem itself, but I'm not expecting much.
