In this one, I only read 疑惑 (Doubt/Suspicion).
As I didn't read an official translation, there are few things that I couldn't get correctly, but it doesn't really matter.
Edogawa Rampo is, by so far, my favourite author. Despite the principal subject which is resolving a case, he can make us reflect on different other things. In 疑惑, Rampo taught us about subconscious and how it has the power to influence our actions (which is in this case, a murder).
I really loved this one and I know that I could love it even more if there was an official translation, but well.
