@sonoci: HAMMERSPACE? O.O. *checks TV Tropes*. Oh I see, but I still think *pulls things out of nowhere* is more(retardedly) badass. Good example:
Also, stop lying sonoci! We know you secretly are one of Gosho's assistants and each of your 4-Komas are meant to be jokes but contain hints toward future cases. fufufu *Conan's I just found out your trick grin*. >:D
Last thing...which case he did that? I can vaguely remember the case that Saito first appeared on which we all knew who the culprit was but not the method used for the killing. Back then the police didn't have a suspect right away. But it's different here...won't the police think the husband is the culprit? The DB and Agasa witnessed their domestic fights, I bet they will think this case was murder by the husband...until Conan starts meddling as always.
That's my reasoning. I don't think this will be too obvious, unless the police thinks this is a suicide, which would be stupid because the wife was absolutely ready to kill him.
