I've been reading Joe Lansdale and Hap & Leonard for over twenty years now, and I expect I'll keep reading him and this series until he stops writing. He's a natural storyteller with a knack for plotting, and even when I read a mediocre Lansdale story, I still enjoy it.
Unfortunately, Jackrabbit Smile is a mediocre book. It's solid enough, but it's hardly the best in the series, nor is it the best Lansdale has to offer. It lacks the zing of his other books, partly because it's missing the wacky characters, partly because the dialogue isn't as snappy, and partly because the story simply isn't that tight. Lansdale has expanded the Hap & Leonard world to include characters from other books (including those from other writers), and Hap and Leonard lean on them in this story. Plus, the relationships they've built over the series are still there, and it helps them get out of a lot of scrapes that were much more perilous earlier in the series. With Marvin Hanson always vouching for them, they're able to get in and out of trouble without any real concern on the reader's part. By the end of the book, it feels more like an ensemble book than a Hap & Leonard book
As for the story itself, Hap and Leonard are hired to investigate a missing person, but the folks who hire them are racist supremacists, and the town they visit is one where anyone not white is allowed to work there, but they aren't allowed to live there. It feels like a rehash of the themes of The Two-Bear Mambo, even if the story itself is different. For all its build-up, it's anticlimactic at its conclusion, and it feels more like Lansdale is reeling in his loose ends instead of tying them up neatly.
Written by any other writer, Jackrabbit Smile is a decent crime novel. The problem is, this is a Lansdale book, and my expectations for one of those are much higher. At the very least, it's not a good place to start on the series, since it begins further into the main characters' development than is best for new readers. The problem with that is that once readers are caught up, they'll be disappointed with this entry into the series. It seems like a no-win read, despite it being entertaining enough. I understand Lansdale will be taking a break from the series after this book, and I think that's a good thing for the readers.
