Political intrigue is a great backdrop for a mystery. Look at The Manchurian Candidate, The Third Man or any of Henning Mankell’s wonderful Wallander mysteries. A murder can highlight the struggles for power, the needs of the many versus the needs of the few, and the ways people hurt each other at both the micro and macro levels. If they are written well. If they aren’t, the work feels something like Murder Under the Bridge by Kate Raphael.
