Solid Series Starter. This has pretty much everything one would want in a family based PI / police procedural type drama series starter. Complicated family dynamics, a compelling case - where in this particular instance (series?) family members find themselves on different sides of the case -, an interesting mystery, and the storytelling to put it all together quite well indeed.
As is typical of such a series, this is clearly going to be a "freak of the week" type with an overall lore and mythos, and both look to be compelling going forward.
Fans of the genre generally will find a lot to like here, and those who haven't really dabbled in this kind of tale before will also find a lot to like that could potentially bring in new fans.
Ultimately, this is one of those series starter books that does everything it needs to do and does it all quite well.
Very much recommended.
