Aside from my subjective issues with the path Huber chose for these characters, I like this series; you could say I enjoy them in spite of myself. But while this book was a 4 star read on the strength of its plot, it might have been a 4.5/5 star read if not for the weakness of the editing.
The narrative is much longer than it needed to be because Huber, with admirable motivation, spends a lot of time ruminating on the devastation wrought on both the soldiers who fought in WWI, and those left behind to cope in fear and anxiety. She does bring light to many aspects of the horror that is war, especially the first world war, but she spends too much time doing it, and this is a murder mystery, after all. I'm confident a lot of it could have been cut without losing the more important message, and the overall story would have been a lot better for it.
Still, the plot is a strong one, with aspects of scavenger and treasure hunting spicing up what would otherwise be an ordinary nemesis plot running parallel to a murder mystery. I'm still kid enough to enjoy rhyming clues and secret codes, as well as the touch of cloak and dagger when used judiciously, and it is here.
As I opened the post with, I still don't like what Huber is doing with the characters; while there are no love triangles or quadrangles, she has two other men in love with Verity who are dedicated to uncovering the series' plot; there seems to be no plan for this to change and it's tiresome. Luckily, the murder mysteries have so far made up for it. Can't see that lasting much longer though.
