edogawa ranpo book covers

shonen tanteidan / boy detective club

Kobunsha covers

rampo world is an excellent resource! I am obsessed with it!! some of the titles differ between editions, as these versions are older. as far as I am aware, these were (mainly?) illustrated by Kazuo Matsuno

Poplar Publishing covers

primarily illustrated by shigeru yanase (but if you know any more info about the illustrators let me know!!)

shonen tanteidan “rewritten” novels

these were previously published books rewritten to include the boy detectives – I talked about this more here
