This is a really well written engaging and fast paced mystery full of skullduggery, crime mobs, high stakes murder, and at the center of it all, the fixer with a heart of gold, rescuing damsels, protecting orphans, righting wrongs, and exposing the bad guys. In a lot of very good ways, this book reminded me of John D. MacDonald's superlative Travis McGee books, with a dash of Robert B. Parker thrown in for good measure. That isn't to say that this book was derivative, it's not, the author has a masterful grasp of plotting and narrative arc and the nuts and bolts of the story work very well.
There's a fair amount of graphic violence and strong language - murder, mob bosses, embezzlement and the like, and readers who find the "f-bomb" problematic might want to give this one a miss. There's also a short but somewhat graphic description of a small-craft airplane crash with attendant death (it's very short and central to the plot).
Despite being the 14th book in the series, this one works perfectly well as a standalone. I hadn't read any of the other books for at least a couple years (my notes before 2018 were sketchy at best) and I had no trouble following any of the action.
Four stars. Well worth a look.
Disclosure: I received an ARC at no cost from the author/publisher for review purposes.
