The Psychological Test is an early short story by Edogawa Ranpo, one of the grandmasters of Japanese mystery fiction, featuring his famous detective Akechi Kogoro. This was the first piece of Ranpo I've ever read, so it felt like something of a milestone for me. Overall, reading The Psychological Test was an interesting experience, and I liked it, but I was slightly disappointed because I felt like some minor changes could have greatly improved it.
