The Fallen by David Baldacci

 Amos Decker's boss thinks Decker needs a vacation,  but Amos doesn't have any family or friends to visit.  Alex Jamison, his colleague at the FBI, takes pity on him and invites him to come with her as she visits her sister's family in a rundown town in Ohio.  They are not there long before Decker discovers a bizarre murder in the house across the street.  Decker soon learns that there have been a series of strange murders in the town, and decides he is going to help the local police get to the bottom of it all.  As he and Alex investigate, they soon become targets and narrowly escape attempts on their lives. In the economically depressed town, riddled with opiate abuse,  good guys can become bad guys, and no one is as they seem.

This is the fourth in the Memory Man series. I felt like this one had a little different vibe than the earlier ones.  Amos and Alex aren't on an official assignment so there isn't a lot of FBI involvement.  It has more of a small town, cozy mystery feeling.  That being said, I liked it.  Baldacci is really good at laying down clues during the narrative, and then gathering them all up at the end in a way that makes sense.  I also like the Amos and Alex characters, and the way that Amos' unique personality and abilities both tie them together and strain their relationship. I did feel like in the ending of this one there were too many people "conveniently" confessing. I kept thinking of Scooby Doo, "and we would have gotten away with it if it hadn't been for those darn kids." Still, this is another great mystery that a couple might enjoy listening to together on a long road trip, or reading out loud together after dinner each night. (2018, 432 p)
