Everyone is free to judge, but for my part I feel Grangé reapplies the same pattern seen in other novels.
Always a damn talented but whose privacy investigator takes water from all sides.
Always two surveys (but linked left me skeptical ..).
Always the unexpected twists (or unlikely).
Always an explosive finale with an environment "unchained".
Always mention of the same themes (it still revolves around pregnancies).

The evocation of Japan can not raise this novel over the author's volumes.
Certainly it gives a touch of originality, but it also ends up stopping the rhythm of a story that was not ... not necessarily exciting ...

It's a little problem when we present immediately a serial killer: the reader has the impression to know everything from the first chapter, and I was surprised that on conclusion of the first part of the novel. So after a few hundred pages. For a movie, it's not very troublesome. For a novel, one wonders if the form is relevant.
I mean, Kaiken will probably be a good basis for a new film production - like "Crimson Rivers" .... But for a novel, the shortcomings of the scenario are more apparent and rhythm problems may put off some readers.

Too bad, because the whole always has a smooth writing, rather pleasant to read.
