As the title says, what I'm looking for is either Ranpo Edogawa either as a character (e.g. Bungou Stray Dogs) or his works adapted to a manga (e.g. Junji Ito version of The Human Chair). Blame Ranpo Kitan for it - since the novels are old, anything about them would be hard to track down...Aside from the works I used as examples, I haven't read anything else that falls into this category.

P.S. Normally I wouldn't take anything that has sex, but this will be an exception as I know through research The Caterpillar has some.

I know 2 manga/anime that are inspired by Edogawa Ranpo: Detective Conan and The Daughter of Twenty Faces, the latter using characters from Ranpo's works such as Kogoro Akechi and the Fiend with 20 faces

Also, you know a number of Edogawa's novels can be found in English right?

I specifically didn't want works inspired by his stories, so neither of those really fits what I'm looking for. Sorry.

I know some of the novels have been published in English but I already said, since they're kinda old they would be quite hard to track down.
