Premise: In the post-WWII Japan, a young man has just started writing and publishing detective novels, and then cops and fellow citizens began to ask him for advice to solve mysterious murder cases.
The first story is pretty decent, the explanation of murder mystery is fine, but the rest (characters, the murderer's motivation, etc) is just so-and-so. 3.2 stars.
The second story is doing better, it deals with a mysterious disappearance which takes place in a walled small village, it's your usual 'impossible crime' setting, and turns out the explanation is great! It's really difficult to guess how the disappearance was arranged. 4.5 stars
The third story, which is about a mysterious House of Beasts deep in the mountain, how it can trap visitors and it can change from being an one storey building to a two storey building within 5 minutes, it's a reaaaaaaaaalllly tricky story and the explanation is fine, I like it very much. 4.5 stars.
The fourth story takes place in the early days of the novelist's career, the story is neatly written and the explanation for the mystery is pretty good, but it is a bit disappointing that in the story. 3.8 to 4 stars.
If mind games and 'Impossible Crimes' are your things, go try this one!
