I don't really need to review every volume of this series, because it's always the same...
Are the mysteries that good? No, not really. Is it somehow really charming and enjoyable to read? Always yes.
I did find this one a bit more confusing in spots; the editing was really messy, with a number of distractingly sloppy errors. And I wish they'd stop the cliffhanger splits; I get it's supposed to make you anxiously preorder the next volume, but the endings are always so anticlimactic. The pigeon one made so little sense to me, even if the pigeon keeper and his reporter friend were cute. The plot holes are so big it's pointless trying to poke more holes in them.
But the Saku scenes more than made up for the rest. He is so wildly charming, and I adore his adoration of "I'm not interested in a marriage happy ending" Mitsuko. Even though him being in school still makes no sense, when he's hanging out with her at work all the time, or even going on vacation with her!
And he got to meet Mitsuko's mother, too. That was a cute chapter. I...am going to have to look back at the earlier volumes to figure out why her mother kept speaking in French, which was again quite distracting, but I liked the complexity of their relationship.
Mitsuko absolutely hated her father, who shouted to get his way and refused to allow his daughter to do anything that went against his traditional values. Over time, she grew to resent her mother, too, for living exactly the same kind of life that she was trying so hard to defy.
Her mother only did things for her family: buying gifts for her husband and son and nothing for herself, using the same bag and wearing the same clothing for years, and always saying she just wanted other people to be happy. It's genuine, and Mitsuko can't stand it, because she thinks her mother is limiting herself. But it's her mother's choice for her own life.
Different women want different things, and the important part is having the freedom to choose your own path. Mitsuko split away from her family to pursue hers, although she has kept in touch with her mother through letters. So it's not as though she's entirely estranged. But it'll probably still be a long time before she wants to actually visit them.
The rest of the mysteries were one-offs, with new characters and more messages about families and finding your own paths. It's a strong theme for this whole story.
The final one has Mitsuko, Saku, and her boss off on a snowy holiday, where they run into an old man who's devastated by the recent loss of his wife - and the grandson who thinks he might have to give up his life in Tokyo to take care of him.
