少年探偵団

The Youtube reading differed from the Aozora text in the introduction (adding several extra sentences) but seemed to be largely consistent after that point.

An old fashioned kid's detective's story. I'm a fan of golden era detective novels and also very comfortable with older texts at this point, so I enjoyed this thoroughly, but a few call outs for people not familiar with the genre:

• This is an old text (published 1937) so some of the grammar and words used will not be in common use anymore. You'll especially notice this when the young boys are speaking.
• Part of the plot involves Indian mysticism ("oh, you don't know the secret magics that the people of India have!" kind of thing).
• Because the intended audience is kids, there are fewer kanji than you might expect.

Overall this is a fun detective book, fully the type of spooky kids writing I expect from 江戸川乱歩's boy detective series. The plot twists are VERY predictable, but the writing style is so fun I always enjoy it anyways. His works for adults are much more difficult, so if you tried one of his normal novels or short stories and found it too hard you might still be fine with this.
