Harry Bosch, Book 17
Okay, I have to say, Bosch has this most annoying habit of keeping all of his theories and suspicious to himself until he can play them out and confirm every little detail with them. I would f---ing hate working with him because of this trait. I want my coworkers to be working WITH me to an end goal, not hoarding knowledge and ideas that could help the rest of us achieve the goal we have set out for ourselves to accomplish.
This particular habit has become tiresome in this detective.
That all said, this was one of the better Bosch books. Oh, we had someone die. We might have even had a bad cop do it. And we most definitely had tunnels, though perhaps not in the most literal of ways.
There are two cases being solved in this book, the second was a bit too clean and, oh, look, one, two, three, follow the trail to the cold case perp. How convenient. Perhaps the whole idea of hiding in plain sight isn't so far fetched, though, really, this is fiction and all.
Yeah, so, it's a Bosch book. Bosch is getting old and I'm nearing the end of the series. Two more books and I'm done, even if there is another Bosch book after 19. After 19 books, ugh, this series is longer than the Dresden series, and THAT is a series I'll actually actively recommend.
The usual, if you're reading Bosch, clearly there's a reason why, so keep reading recommendation.
