Compared to other popular mystery manga, Q.E.D are much simpler and more fun to read. Anyone who loves math and science would exceptionally love this manga. The art looks average, but since it plays the main role in leading reader's perspective. I would like to give a high score in the art not for the style but for the author's ability to use picture as main mystery point. Anyway, for anyone who wants to enjoy both text and picture aspect of manga, this manga is highly recommended.
