The Perfect Father

Nonfiction about Chris Watts, the guy who had an affair and wanted to start his life over so he murdered his pregnant wife and two young children. He strangled his wife to death and drove for an hour to his work site to bury her, he'd brought along his children who were crying, then he killed them too and stuffed their bodies in oil tanks. Then he went to work like nothing happened.

It got really famous because the wife's friend quickly realized something was wrong mere hours after she was killed, bringing the cops to the house for a welfare check and giving Chris zero time to set the stage for a cover story. There is police body cam footage and you can see Chris behaving guilty as hell and having an internal breakdown of how caught he is.

The Bosch books are really good. I think my favorite might be A Darkness More than Night but The Last Coyote is also great. I fell off the series after awhile because the author has the books set in "real time" so Bosch gets old, retires, comes back, retires, and new characters have to be brought in because he's too old, etc.
