Detectives have always been a popular subject in manga, but what is the best detective manga of all time? Is the hit series Case Closed the top title on this interactive poll of manga about detectives and mystery? It's hard to say it isn't, given that the series has been running since 1994! But maybe you prefer heavier stories like that of Monster or Death Note? The latter of those two isn't strictly about detectives, but there is a lot of police work and investigating that is central to the manga's plot. No matter what your preferences are, vote for all the good detective manga on this list that you feel others should definitely read.
Feel free to add any manga with detectives that may have been overlooked, too. If you're going to downvote a title, please only do so if you've actually read it.
