The Honjin Murders by Seishi Yokomizo
The Honjin Murders, set in 1937 in a rural Japanese village, is told by an unnamed narrator who is telling what he learned from the people close to the crime. The eldest son of a wealthy family was marrying a beautiful, talented, but lower-class, woman. But on the wedding night, the family heard terrible screams coming from the bedroom of the newlywed couple, the door and the windows were locked, and the couple was found stabbed to death. Detective Kindaichi was summoned by the bride's uncle, to investigate the double murders.
While the characters are not well-developed, we get a definite feel for the culture and traditions of the time. The plot was intricate and had several twists. The narrator plays fair with us, even going so far as to point at what is significant and what can be ignored.
I can't say I love a good locked-room mystery. The murder method can get a little overly complicated, which quite honestly was...
