Prime Suspect is one of my all-time favorite detective television shows. Helen Mirren stars as Jane Tennison, one of the few female Detective Chief Inspectors in London. The series follows her as she fights against institutionalized sexism, her own destructive personality, and solves some pretty gnarly crimes. It is incredibly well made and Mirren is absolutely brilliant. I highly recommend the show as you can see from the review I wrote of the complete series that came out on Blu-ray a few years back.
