The last few months I’ve been dipping into the Rabbi Small murder mysteries, which are written by author and professor of English Harry Kemelman (1908–1996). The series is in the Amateur Sleuth sub-genre. In this case the amateur who is constantly solving murders is a Jewish rabbi.
The Tony Hillerman books (Leaphorn and Chee) are filled with Navajo background. The Jonathan Gash books (Lovejoy) are filled with antiques background. The Lawrence Block books (Bernie the burglar) are filled with burglary background. In all cases, this background enriches the reading and can be educational (the Hillerman books especially).
Harry Kemelman’s books are enriched by all the Jewish background.
