Black Cherry Blues is the third Dave Robicheaux novel and the second one I read. It starts out in the bayou of southern Louisiana. Rob is still recovering from the murder of his wife some time earlier. He’s quit is law enforcement jobs and runs a fish and tackle business way out in the sticks. His biggest concern is his adopted child Alafair (not by coincident Burke’s real life daughter who’s also a mystery writer).
An old roommate, once famous musician Lee Pugh, now fallen on hard times, visits to enlist Robicheaux’s help. He’s overheard a conversation between two colleagues discussing a murder. Robicheaux isn’t interested, but after Lee begs him for help he intercedes with the employers of the two men. Next thing he knows, the two men threaten Alafair.
