This is a very good first novel and series opener. It does a good job of introducing the main character, the setting, telling a decent story with a little mystery and all of that.
Setting: Yellow Springs, Ohio is on the cover, as prominent as the protagonist, Jackson Flint, and it's obvious the author intended Yellow Springs (and Dayton) to be a co-lead character. Repeatedly, Flint and other characters mention their love for Yellow Springs, and author Geisel does a good job of presenting the appropriately quirky village to us.
Detective: Jackson Flint checks all the boxes for a series P.I. He's an ex-cop, work-out freak, gun expert, no frills, quirky and incongruously literate tough guy, with a friend on the other side of the color-line who is all that taken to the next level who is also uber loyal to our lead character and ready and available to join in the mayhem at a moment's notice. Geisel gives us a few glimpses into Jackson Flint's past, as a way of explaining small pieces of his backstory. And there is one piece that is sort of a tragic past.
Mystery: Enjoyable, but fairly transparent. Geisel doesn't provide many options for who the bad guy might be. He was not subtle in dropping hints, and there was little attempt at misdirection. The first two thirds of the book, as the mystery is laid out and Jackson hunts for the missing people, has enough suspense to keep the pages turning. As the strong suspicion of the evildoer's identity was turned to absolute certainty, the momentum slowed during the lead-up to the denouement and the revelation and defeat of the culprit was a little anti-climatic. Enjoyable, but a little punchless. And that's not necessarily a bad thing. I remember reading Elvis Cole books and wondering how Robert Crais managed to be more over-the-top than The A-Team. Some series are barnburners and some are not. Some people like action-packed barnburners, and some like cozies.
I admit, I like my mystery series with some action and danger in them, and I admit that's a limiting flaw of mine. But it's what I want. Despite a couple of action scenes, this was more cozy than violent calamity. This was not as neutered as a Margaret Maron book, but it's not as punchy as a Spenser book either. Although, I'll say Jackson Flint probably manages to be even more of a perfect human than Spenser and Judge Knott combined.
Everything just seemed a little too perfect. The village of Yellow Springs. Jackson Flint being a brawny brainy sensitive Whitman+Shakespeare quoting, healthfood eating, perfect man of a single father. Really, his crap doesn't stink. I'll bet Yellow Springs doesn't even have a dump - they probably dump their stinky trash in a place appropriately somewhere else. And Brick is, in different ways and some similar ways, more perfect than Jackson. They're like the Michael Jackson and Paul McCartney of modern-day PIs.
In the end, I really enjoyed this first novel, series opener. Scott Geisel has a good way with words, a good way of presenting his characters, and an inviting way of spinning a tale. Despite the sheer unrealistic perfection of the regular characters and Yellow Springs, I liked being a part of their world for a couple of days. I'll be around for the next installment, and that's high praise from me. Geisel shows a lot of promise here. I'll be back when Jackson Flint comes back!
