Finished this one tonight. I learned some about race, & it was an interesting mystery, although I had a guess about the killer early one. What is up with detectives/police and substance abuse? I guess this trope goes back a long way, even Holmes abuses cocaine. The main character is a flawed man, & there are times when he‘s frustrating, but he‘s a realistic character. I read this for book club, but I think I‘ll continue the series.
