I picked up this book because it's been recommended by several well-known authors of locked-room murders. It was promising when I started reading because the language was easy to follow (perhaps credits to the translator) and the plot was interesting, straight-to-the point, and fast-paced. In the end, though, I found the solution to the mystery itself unbelievable, and the characters flat. I have a hard time following stories when I can't care less about the characters, and this story barely gave me anything about the bride and groom, who were, after all, the main characters in the mystery (aside from the detective). Maybe this book was groundbreaking in its time, but it's not for me.
