The fourth Hiro Hattori mystery
By Susan Spann
Available August 2nd from Seventh Street Books (Prometheus Books)
I have not read the previous Hiro Hattori mysteries, but it was easy to catch up on the basics. Hiro is a ninja in disguise as a ronin, following mysterious orders to protect a Portuguese priest. Said priest, Father Mateo, keeps getting him involved in solving crimes when he'd rather focus on protecting his charge.
Their latest mystery hits close to home for Hiro, however. Emi was found strangled on the banks of a river by a young man she had been flirting with. The officials are uninterested in her case since she was just a daughter from an acting family. Secretly, her father is a former ninja and uncle to Hiro. He calls upon their family ties to get Hiro interested in who killed Emi.
You don't have to know much about Japanese history to enjoy THE NINJA'S DAUGHTER, but it does make parts more fun. For instance, there are many nods to famous figures of sixteenth-century Japan. Mostly, the outsider of Father Mateo is used to introduce cultural concepts. One he struggles with is the fact that Emi would've been seen as more respectable as a prostitute than what she was -- an actor's daughter who liked to walk with men by the river. (The book is ambiguous about whether Emi ever actually worked as a prostitute to further her dreams.)
I found Emi a compelling murder victim, a woman out of her time and place, who wanted a career instead of a husband and children. There's a good mix of people with motive to kill her. I came to find the title a bit distasteful, since Emi deserved a title focused more on who she was than her father, especially since many people were interested in finding out who killed her for money or ambition or anything but justice for her. The ending brought me right back around to liking it, fortunately.
There's also an ongoing plot about Hiro and Father Mateo's relationship. Father Mateo reveals a secret past that I found disappointing, and I can't imagine long-time readers would find much more satisfying. But I did enjoy how clearly protecting Father Mateo is more than a job to Hiro, and the bond of mutual respect between the men. I'm curious what will happen to them in the next book, since Father Mateo had to flee the city in fear of the shogun, straight to the home of Hiro's clan.
If you like your mysteries with immersive settings and complex motives, THE NINJA'S DAUGHTER is a good choice. I'm not rushing out to read the earlier books, but I'll certainly pick them up if they cross my path.
