Hirai Tarō (平井 太郎), better known by the pseudonym Rampo Edogawa ( 江戸川 乱歩), sometimes romanized as "Ranpo Edogawa", was a Japanese author and critic who played a major role in the development of Japanese mystery fiction.
Well, what can I say about Rampo Edogawa and his "Shounen Tantei" series that I haven't said before? Not much, probably. But I will try.
We get back to our Kobayashi (and his pretty and rosy cheeks) and his army of primary school detectives. We get back to mysterious occurrences that you know from page one where will they lead to. We get the special appearance of famous detective Akechi. We get some of those amazing flights of fancy that are so typical in his novels (here for all the ages). We get some moments that we have seen before and we will see again in other books of the series (the biggest danger in this series is that is basically the same book over and over).
But it is still fun, some moments are really original and surprising, and there is the same cheeky, mischievous fun that permeates the whole novel and that is so typical of Edogawa's writing style and mood creation. It is not a perfect book, but it is a whole lot of fun.
The best: some creative moments; the mood and the tongue-in-cheek writing style; the characters
The worst: You have read all before with just some differences in situations and environments
Other options: any other book in the series, in particular the really funny first one; you can also read "The Three Investigators" for some old style detectives; if you are a little older, I recommend Edogawa for adults (he is just great)
