Could be with Super Junior or any other fandom of course too.

And actually it'd be a game between the writer (the killer) and the reader (the policeman) - as the the writer's role to lie the reader into believing the plot. Also to make it fun I shouldn't use my usual fav characters the way I do - I like Toshiya, so it'd be no fun making him the killer. On the other hand I like Toshiya so I shouldn't leave him out all protected. Hm... interesting :D Pity with my imagination don't go my writing skills... :(
