Tree of Redemption, Jim Davidson, 2022
Chris Harrison travels from suburban Virginia to Laredo, Texas, because Armando, his dear friend and father figure, has died. Armando's family is a very well-respected, and very old, family (maybe going back to the Mayan Indians).
While staying at the family estate, Chris is told that Armando was murdered. There is no chance of Chris going back to Virginia, and forgetting about it. His first stop is at the local police station; they are no help. He learns later that that was a very bad idea. The police are totally corrupt. If they weren't involved in Armando's murder, they probably know who did it and aren't interested in justice.
There are people in Laredo who don't like questions about Armando's murder, and it's only a matter of time before they fight back. Chris has a couple of people on his side, including his estranged father. These are people who know how to get things done. Does Chris find out the truth about Armando's murder? How far does the coverup go? Who is still alive at the end of the story?
This is a gem of a story. Mystery/suspense stories are not limited to New York City or Washington DC; they can happen anywhere. Here is a tale that will very much keep the reader's attention.
